                 Why the rising gold price has a direct impact on our work as goldsmiths 
 The price of gold has reached a historically high level in a short space of time. For many, this is a topic in the news - for us as goldsmiths, it is a daily reality. Because rising gold prices not only influence the market, but also design, planning and advice on high-quality jewelry. 
 We would like to show you  what the current gold price trend means for our work at Wiesner Schmuck  - and what it means for our customers. 
 Gold: stable in value, coveted and limited 
 Gold has accompanied mankind for thousands of years. Its special material stability, warm color and emotional value make it unique to this day. At the same time, gold is a finite resource. The amount of gold mined worldwide is limited and the extraction of new deposits is costly. 
 If demand increases - for example in times of economic uncertainty - this has a direct impact on the price. This is exactly what we are currently experiencing: gold is increasingly in demand as an investment, which is driving up the price of the material significantly. 
 What the high price of gold means for our work 
 As goldsmiths, we often plan pieces of jewelry months in advance. A strongly fluctuating gold price makes this planning more challenging. Material costs change, while our quality standards remain the same - or even increase. 
 At Wiesner Jewelry, we respond to this with 
 
 
  thoughtful design  that uses materials efficiently 
 
 
  precise craftsmanship , where every gram counts 
 
 
  honest advice  so that prices remain transparent 
 
 
 Our aim is to create jewelry that lives from  design, quality craftsmanship and personal meaning , not from the materials used. 
 When gold is more expensive than expected 
 Many customers are surprised at how much the price of gold has risen recently - especially in comparison to other precious metals such as platinum. This change in the price ratio is an important topic for us to advise on. 
 We take the time to explain 
 
 
 why prices look different today than they did a few years ago 
 
 
 what design alternatives are available 
 
 
 how budget and desired design can be sensibly harmonized 
 
 
 Because high-quality pieces of jewelry are not created by mass production, but by smart decisions. 
 Old gold: personal, sustainable and more relevant than ever 
 With rising gold prices, interest in old gold is also growing. Many of our customers bring in existing pieces of jewelry or leftover gold and have something new made from it. 
 This has several advantages: 
 
 
 existing material is put to good use 
 
 
 emotional memories are preserved 
 
 
 the material value is optimally utilized 
 
 
 Right now, it is becoming clear how valuable this approach is. Jewelry and    Wedding rings made from old gold    combines sustainability with individuality - and goes perfectly with handmade goldsmithing. 
 Quality remains - regardless of the gold price 
 No one can reliably predict how the price of gold will develop. Whether it stabilizes or declines, we are certain that real jewelry is always more than just a material value. 
 At Wiesner Jewelry, we focus on: 
 
 
 long-lasting design 
 
 
 timeless aesthetics 
 
 
 honest craftsmanship 
 
 
 This results in pieces of jewelry that retain their value - emotionally and materially.

                 Gold, platinum or palladium - which precious metal suits your piece of jewelry? 
 Choosing the right precious metal is one of the most important decisions when making or selecting a piece of jewelry. Gold, platinum and palladium differ not only in price, but also in color, weight, suitability for everyday use and craftsmanship. From the jewelry workshop&#039;s point of view, there is no general &quot;best&quot; precious metal - the decisive factor is which material suits your wearing habits and the planned piece of jewelry. 
 Gold - the versatile classic 
 Gold is almost exclusively alloyed in jewelry. This results in different colors such as yellow gold, white gold or rose gold. Gold alloys are very easy to shape and repair, which makes them particularly suitable for many pieces of jewelry. 
 In the workshop, we value gold for its versatility and long tradition. The hardness and therefore suitability for everyday wear varies depending on the fineness. 
 Platinum - durable and particularly resistant 
 Platinum is a very dense and resistant precious metal. It is usually processed with a high fineness (e.g. 950) and is ideal for jewelry that is worn every day. 
 Signs of wear on platinum usually appear as a fine patina, not as a loss of material. From a technical point of view, platinum is more difficult to work with, but offers exceptional longevity. 
 Palladium - a light-colored precious metal from the platinum group 
 Palladium belongs to the platinum group and is often used in jewelry as an alternative to white gold. It has a natural, light color and is lighter than platinum. 
 Whether palladium is the right choice depends heavily on the specific alloy and the desired design. Expert advice is particularly important here. 
 Knowledge from the workshop 
 Gold, platinum and palladium each have their own strengths. The best choice results from the interplay of design, wearability, budget and craftsmanship. 
 In our overview of   precious metals in the jewelry trade  , you will find the most important basics on materials, properties and processing.

                 What do 585, 750 and 950 mean? Fineness simply explained 
 Numbers such as 585, 750 or 950 can be found on many pieces of jewelry. These figures are referred to as  fineness  and provide information on how much pure precious metal is contained in an alloy. 
 What is a fineness? 
 The fineness describes the proportion of precious metal in thousandths. For example, a fineness of 585 means that 585 out of 1000 parts consist of pure gold. 
 Typical fineness in jewelry 
 
  Gold 585  - 58.5 % gold 
  Gold 750  - 75.0 % gold 
  Platinum 950  - 95.0 % platinum 
  Silver 925  - 92.5 % silver 
 
 Why are precious metals alloyed? 
 Pure precious metals are often too soft for everyday use. By adding other metals, hardness, color and durability are specifically influenced. 
 Workshop tip 
 A higher fineness does not automatically mean a &quot;better&quot; piece of jewelry. The decisive factor is the right alloy for the intended purpose. 
 Further information on   precious metals and alloys   can be found in our central guide.

                 Which precious metal does not tarnish? 
 Many jewelry wearers sooner or later ask themselves this question:  Which precious metal does not tarnish?  Discoloration, dull surfaces or dark spots are often perceived as a quality defect. In practice, however, these are usually  natural surface reactions  that vary depending on the precious metal. 
 The decisive factor is therefore not only the precious metal itself, but also its  alloy ,  surface treatment ,  wearing habits  and contact with environmental substances. From the perspective of the jewelry workshop, it is easy to explain which metals can tarnish - and which cannot. 
 
 What does &quot;tarnishing&quot; mean in jewelry? 
 Tarnishing is a chemical reaction on the surface of a metal in which compounds form with oxygen or sulphur. This reaction usually only affects the outermost layer and has no influence on the stability or value of the piece of jewelry. 
 Typical triggers for tarnishing are 
 
 Air and humidity 
 Sweat and skin contact 
 Cosmetics, perfume or hairspray 
 Household chemicals 
 certain environmental influences (e.g. sulphur compounds) 
 
 Important: Tarnishing is  not a sign of inferior quality , but a typical property of certain precious metals. 
 
 Silver - why it tarnishes particularly often 
  Silver  is the precious metal most frequently associated with tarnishing.  Sterling silver (925) , which consists of 92.5% silver, is usually used in jewelry production. 
 Silver reacts particularly sensitively to sulphur compounds in the air. This produces silver sulphide, which appears as a dark coating on the surface. This reaction can already occur during normal storage - even if the jewelry is not worn. 
 It is important to know from a workshop perspective: 
 
 Tarnishing is  superficial  
 It can be  easily removed  
 The substance of the piece of jewelry remains completely intact 
 
 With suitable cleaning or professional refurbishment, silver jewelry can be restored to its original condition at any time. 
 
 Gold - very durable, depending on the alloy 
  Gold  is one of the most chemically stable metals. Pure gold (fine gold 999) does not tarnish and does not change its surface. In jewelry, however, gold is almost always  alloyed , as fine gold would be too soft for everyday use. 
 Whether gold tarnishes therefore depends primarily on the  fineness  and the  metals added : 
 
  Gold 750  and  gold 585  are very stable 
 Very low purity (e.g. 333) may show slight changes 
 White gold can react somewhat more sensitively due to alloy components 
 
 In practice, gold jewelry is usually extremely easy to care for. Changes are caused more by  mechanical stress  (scratches, loss of shine) than by chemical tarnishing. 
 
 Platinum - extremely resistant and non-tarnishable 
  Platinum  is one of the most resistant precious metals of all. It does not react with oxygen or sulphur and therefore  does not tarnish . 
 In jewelry, platinum is usually processed with a very high fineness (e.g. 950). The material is dense, heavy and extremely durable. Changes to the surface are only caused by  mechanical action . 
 These are expressed as a so-called  patina : a fine, even surface structure that many wearers even find particularly precious. 
 
 Palladium - a light-colored precious metal with high stability 
  Palladium  belongs to the platinum group and has similar properties to platinum. It is chemically very stable and also  does not tarnish . 
 Palladium is often used in jewelry as an alternative to white gold. The natural, light color is permanently retained without the need for additional surface finishing. 
 Palladium also shows signs of wear exclusively through mechanical stress, not through chemical reactions. 
 
 What role does the surface finish play? 
 Whether changes are visible depends not only on the precious metal, but also on the chosen surface finish: 
 
  Polished surfaces  show scratches more quickly 
  Matt surfaces  appear more even 
  Textured surfaces  conceal signs of wear 
 
 From the workshop&#039;s point of view, the surface can be selected in such a way that it optimally matches the wearing behavior. 
 
 Conclusion from the jewelry workshop 
 The question &quot;Which precious metal does not tarnish?&quot; can be answered clearly: 
 
 Silver can tarnish - but is easy to clean 
 Gold is very stable, depending on the fineness and alloy 
 Platinum and palladium do not tarnish 
 
 The decisive factor is always the interplay of material, alloy, surface and everyday use. Expert advice will help you choose the right precious metal for long-term enjoyment of your jewelry. 
 We have summarized basic information on   precious metals in everyday life   for you in our central guide from the perspective of the jewelry workshop.

                                            A fascinating psychological look at why people wear gold or silver: while silver often stands for restraint and learned invisibility, gold symbolizes self-worth, visibility and inner permission. Jewelry as a mirror of the nervous system - instead of just a question of style.

                 Jewelry is not an accessory - it is a statement of your nervous system 
 Many people believe they choose gold or silver for purely aesthetic reasons. A stylist who has worked with Italian executives for years strongly disagrees:   &quot;Jewelry is never just decoration - it&#039;s a revelation.&quot;  
 What sounds like a fashionable slogan turns out, on closer inspection, to be an astonishingly consistent observation about personality patterns, psychological imprints - and about how visible we want to make ourselves in life. 
 Silver: the metal of invisibility 
 &quot;Gold reflects. Silver absorbs,&quot; explains the stylist.  And this difference is not just physical, but psychological. 
 In an evaluation of 120 clients, a remarkable pattern emerged: 
 
 
  Each  of those who consistently wore silver 
 
 
  grew up in an environment  where standing out led to problems.  For example, due to loud parents, changing criticism or the family rule:   &quot;Don&#039;t make trouble. Don&#039;t stand out.&quot;  
 
 
 The nervous system of these people learned early on:   Invisibility is safety.  
 Silver thus becomes an unconscious protective shield - elegant, stylish, but restrained. A metal that leaves space instead of taking it. 
  &quot;Silver is the metal of self-harmlessness.&quot;  
 A CEO who only wore silver involuntarily put it in a nutshell. Despite a seven-figure income, he said: 
 
  &quot;Gold feels like I have to justify myself.&quot;  
 
 His father, he continues, always mocked expensive things.  Silver became an aesthetic compromise: beauty - without the responsibility of being seen. 
 Gold: the metal of permission 
 It becomes interesting when the stylist observes her clients who changed their jewelry habits after therapeutic work. 
 Many switched from silver to gold - and gave the same explanation almost word for word: 
 
  &quot;I no longer feel guilty when I take up space.&quot;  
 
 Here it becomes clear:   Gold is less a symbol of wealth than one of self-worth . 
 Gold reflects - literally and figuratively.  It doesn&#039;t say:  &quot;Look, I&#039;m rich.&quot;   It says:  &quot;I exist - and I don&#039;t apologize for it.&quot;  
 Those who wear gold allow themselves visibility.  No exaggeration, no ostentation - but presence. 
 Gold and silver as an emotional compass 
 The stylist&#039;s statement sums up the phenomenon perfectly: 
  &quot;Silver is chosen by people who have learned to make themselves small. Gold is chosen by people who have learned to assert themselves.&quot;  
 This does not mean that every silver fan has low self-esteem or that every gold wearer is self-confident. But it does show: 
 
  The choice of metal is often less a question of style - but a message from the nervous system.  
 
 Jewelry not only shows how we want to look.  It shows how we feel inside.

                  Ruthenium - The discreet precious metal with great potential  
  What is ruthenium?   Ruthenium is a rare, silvery-white transition metal from the platinum group of metals. It was discovered in 1844 by the Russian chemist Karl Ernst Claus and is named after Russia (&quot;Ruthenia&quot;). Chemically, it is very resistant to corrosion and has an extremely high melting point of around 2,300 °C. 
  Use in industry   Ruthenium is used in many high-tech applications. These include the hardening of platinum and palladium alloys, the production of electrical contacts and its role as a catalyst in chemistry. Its properties make it a versatile but previously underestimated metal. 
  Ruthenium in jewelry production   Ruthenium is still a niche material in the jewelry sector. It is mainly used as an alloy additive to make white gold or platinum darker, harder and more abrasion-resistant. Ruthenium is particularly popular as a coating for silver or stainless steel, as it gives them an anthracite to black-grey, elegant surface. 
  Design and trends   Pure ruthenium jewelry is extremely rare, as the metal is difficult to work with. In recent years, however, the demand for black or dark jewelry has increased - especially for men&#039;s rings or modern wedding rings. Ruthenium coatings provide a striking look with high wearing comfort. 
  Care and value   Coated ruthenium jewelry is relatively easy to care for and resistant to scratches. Nevertheless, gentle cleaning with a soft cloth is recommended. The material value is comparatively low, which does not make ruthenium a classic investment precious metal - but it does offer long-term potential due to its technical properties. 
     Ruthenium is a precious metal for individualists. If you are interested in dark, modern pieces of jewelry, ruthenium-coated jewelry is a stylish choice with added technical value.

                 Osmium - The most exclusive precious metal in the world 
 The rarest and heaviest precious metal on earth 
  Osmium &amp;nbsp;is considered the densest and rarest precious metal in the world. It belongs to the platinum group of metals and is only found in tiny quantities in the earth&#039;s crust - only around one tonne of osmium is extracted worldwide each year.&amp;nbsp; 
 With its  silvery-blue sheen  and unique  crystalline surface , osmium stands out clearly from gold, silver or platinum. No other metal reflects light in such an intense, almost diamond-like way. 
 From raw material to work of art: crystalline osmium 
 In its original, powdered form, osmium is unstable and harmful to health. It is only through a complex  crystallization process  that it becomes the fascinating material that is used today in luxurious jewelry. 
 Each crystal is naturally unique -  no two structures are the same . This makes every piece of osmium jewelry truly unique. 
 Osmium in the world of jewelry 
  Crystalline osmium  has found its place in the world of high-end jewelry. Whether  rings, pendants, cufflinks or watch dials  - designers and collectors appreciate the unmistakable shine and extreme rarity of the metal. 
 With a price that is  higher than gold and platinum , osmium is considered the  precious metal of superlatives . It symbolizes luxury, exclusivity and individuality - perfect for people who are looking for the extraordinary.

                 Was ist wertvoller, Gold oder Platin? 
 In der Welt der Edelmetalle haben sowohl    Gold    als auch    Platin    seit Jahrhunderten ihren festen Platz als Symbole für Reichtum und Luxus. Doch wenn es darum geht, zu entscheiden, welches der beiden wertvoller ist, gibt es keine einfache Antwort. Verschiedene Faktoren wie Preis, Seltenheit, industrielle Nutzung und kulturelle Bedeutung spielen eine Rolle bei der Bestimmung des Wertes dieser Metalle. In diesem Blogbeitrag werden wir diese Aspekte genauer betrachten und versuchen, ein klareres Bild davon zu zeichnen, welches Metall in welchem Kontext als wertvoller angesehen werden kann. 
 Historische und kulturelle Bedeutung 
 Gold hat eine tief verwurzelte historische und kulturelle Bedeutung, die bis in die Antike zurückreicht. In vielen Kulturen wurde Gold als Symbol für göttliche Macht und unvergänglichen Reichtum verehrt. Es diente als Währung, Schmuck und sogar als religiöses Symbol. Auch heute noch hat Gold eine bedeutende Rolle in der Finanzwelt, sei es als Anlageform oder als Währungsreserve für Zentralbanken. 
 Platin hingegen wurde erst im 18. Jahrhundert in Südamerika entdeckt und als eigenständiges Edelmetall erkannt. Seine Verwendung und sein Ruf wuchsen im Laufe der Zeit, und heute ist Platin ebenfalls ein Symbol für Luxus und Exklusivität, besonders in der Schmuckindustrie. Platin wird jedoch auch wegen seiner industriellen Anwendungen hoch geschätzt, was ihm einen zusätzlichen Wert verleiht.

 Preis und Marktwert 
 Der Marktwert von Gold und Platin schwankt im Laufe der Zeit und wird von verschiedenen wirtschaftlichen und geopolitischen Faktoren beeinflusst. Traditionell war Platin teurer als Gold, da es seltener ist und eine höhere Schmelztemperatur hat, was seine Verarbeitung aufwendiger macht. In den letzten Jahren haben sich die Preise jedoch angenähert, und es gab sogar Phasen, in denen Gold teurer war als Platin. 
 Aktuelle Marktdaten zeigen, dass der Preis für Platin oft stark von der Nachfrage in der Automobilindustrie abhängt, wo es als Katalysatormaterial verwendet wird. Gold hingegen wird hauptsächlich als Anlage und Währungsreserve betrachtet, was es besonders in wirtschaftlich unsicheren Zeiten begehrt macht. Somit kann der Wert von Gold und Platin stark variieren, abhängig von den aktuellen Marktbedingungen und der globalen wirtschaftlichen Lage. 
 Industrielle Anwendungen 
 Ein wesentlicher Unterschied zwischen Gold und Platin liegt in ihren industriellen Anwendungen. Gold wird aufgrund seiner hervorragenden Leitfähigkeit und Korrosionsbeständigkeit in der Elektronikindustrie verwendet, etwa in Verbindungselementen, Schaltern und Leiterplatten. Seine Anwendungen sind jedoch im Vergleich zu Platin begrenzt. 
 Platin hingegen hat umfangreiche industrielle Anwendungen. Es wird in Katalysatoren für Autos verwendet, um schädliche Emissionen zu reduzieren, in der Chemieindustrie als Katalysator für verschiedene Prozesse und in der Medizin für Geräte wie Herzschrittmacher und Krebsmedikamente. Diese breite Palette an Anwendungen trägt dazu bei, dass Platin in vielen Bereichen als unverzichtbar gilt. 
 Seltenheit und Verfügbarkeit 
 Platin ist seltener als Gold. Die jährliche Produktion von Platin beträgt nur einen Bruchteil der Goldproduktion, was es zu einem der seltensten Metalle der Erde macht. Diese Seltenheit trägt erheblich zu seinem Wert bei, besonders in Industrien, die auf seine einzigartigen Eigenschaften angewiesen sind. 
 Gold ist zwar häufiger als Platin, aber immer noch sehr selten. Seine weite Verbreitung und die lange Geschichte als Währungs- und Wertaufbewahrungsmittel machen es jedoch zu einem beständigen und begehrten Gut. 
 Umwelt- und Sozialaspekte 
 Die Gewinnung von Edelmetallen hat erhebliche Umwelt- und Sozialauswirkungen. Der Abbau von Gold und Platin erfordert oft große Mengen an Energie und Wasser und kann zur Verschmutzung von Böden und Gewässern führen. Zudem sind die Arbeitsbedingungen in den Minen oft hart und gefährlich. 
 In jüngster Zeit gibt es jedoch Bemühungen, nachhaltigere und fairere Praktiken in der Edelmetallindustrie zu fördern. Zertifizierungen wie Fairtrade und umweltfreundlichere Abbaumethoden gewinnen an Bedeutung und können den wahren Wert dieser Metalle in einer zunehmend umweltbewussten Welt beeinflussen.

                 The origin and significance of white gold in the jewelry industry 
 White gold, an almost colorless gold alloy, was first developed in Pforzheim in 1912/13. It was created as an inexpensive and punchable substitute for platinum and quickly found its way into the world of jewelry. White gold became known as &quot;or gris&quot; (grey gold) in the French-speaking world and became the material of choice for jewelry designed to show off colorless diamonds. Before the development of white gold, silver, platinum and the slightly darker and lighter palladium were the materials of choice, but each had its own disadvantages. 
 The history and development of white gold 
 White gold arose from the need for a material for jewelry that was easy to work with and resistant to tarnishing. Before 1912, there were no pieces of jewelry made from white gold, as it simply did not exist. Silver, although inexpensive and easy to work with, tends to tarnish and lose its shine as a result. Platinum, on the other hand, was more expensive and more difficult to work with. Palladium, a platinum by-product metal, was a good alternative, but also darker and lighter than platinum. 
 The jewelry industry was looking for a material that combined the advantages of these metals without their disadvantages. Thus white gold was born. This new alloy made it possible to display colorless diamonds in all their glory without the material itself tarnishing or discoloring. 
 What is white gold? 
 White gold is a gold alloy that is given a pale white color by the addition of decolorizing metals. These metals, which are added to the gold to give it its characteristic color, are mainly palladium, nickel or, if the gold content is low, silver. The decoloration of the naturally yellow gold occurs continuously and requires a certain amount of these decolorizing additives. 
 Palladium is a platinum by-product metal that is often used to give white gold its color. Nickel used to be widely used but is less common nowadays due to its allergenic properties and legal regulations. Silver is used at lower gold contents to achieve the desired color. The remaining part of the alloy, which is still missing up to the calculated total volume, is often completed from a mixture of copper and silver. 
 The properties of white gold 
 White gold has several advantageous properties that make it a popular choice for jewelry: 
 
  Tarnish resistance:  unlike silver, white gold does not tarnish and retains its shine over long periods of time. 
  Hardness and durability : White gold is harder than pure gold and is therefore ideal for making jewelry that is worn every day. 
  Elegant appearance:  The almost colorless appearance of white gold allows diamonds and other precious stones to stand out particularly well. 
  Versatility:  White gold is easy to work with and can be incorporated into a variety of jewelry designs. 
 
 The use of white gold in the jewelry industry 
 White gold is used in a variety of jewelry, including rings, necklaces, bracelets and earrings. It is particularly popular for engagement and wedding rings, as its neutral color enhances the brilliance of diamonds while being durable and easy to care for. 
 In the manufacture of white gold jewelry, rhodium plating is often applied to give the jewelry an additional shine and increase the surface hardness. However, this rhodium plating needs to be renewed occasionally as it wears off over time. 
     
   Here is an example of white gold wedding rings from Gerstner   
 Advantages and challenges of white gold 
 White gold offers many advantages, but there are also some challenges that need to be considered. The rhodium plating that is often applied to white gold to give it extra shine can wear off over time and needs to be renewed. In addition, white gold is more expensive to produce than yellow gold, as the decolorizing additives and the manufacturing process are more costly. 
 Despite these challenges, white gold remains one of the most popular choices for high-end jewelry due to its unique properties and elegant appearance. 
 All in all... 
 White gold has become one of the most important materials in the jewelry industry since its introduction over a century ago. Its tarnish-resistant, elegant appearance and ability to show off diamonds particularly well make it a popular choice for jewelry lovers around the world. The addition of decolourizing metals such as palladium, nickel or silver gives the originally yellow gold its characteristic white-pale color, which sets it apart from other gold alloys.

                 Historical facts about platinum: 
 It must be assumed that&amp;nbsp; Platinum &amp;nbsp;was first used around 3000 BC. Today, metallic platinum is practically no longer mined. There are only mines in South Africa. In the production of non-ferrous metals such as copper and nickel, platinum metals are a by-product of nickel refining. There are five by-metals in the platinum group. Rhodium, osmium, iridium, palladium and ruthenium. These by-metals are so similar to platinum that they initially caused great difficulties in the extraction of pure platinum. Platinum is a corrosion-resistant, soft and malleable precious metal. It is also suitable for the production of high-quality wedding rings and&amp;nbsp; engagement rings  due to its high tarnish resistance, durability and rarity. We process platinum in both the&amp;nbsp;  Mokume Gane wedding rings Seraya  as well as in our&amp;nbsp; zodiac rings , but also in engagement rings.&amp;nbsp; 
 General description of platinum: 
 Platinum is a rare, dense and corrosion-resistant metal that is used in the jewelry industry, electrical engineering and the automotive industry. It has a high electrical and thermal conductivity and is an important catalyst in chemistry. Platinum is a precious metal and is valued as an investment and jewelry metal. The largest deposits are found in South Africa, Russia and Canada.&amp;nbsp; 
 What role does platinum play in the jewelry industry&amp;nbsp; 
 In the jewelry industry, platinum is valued for its hardness, density and resistance to impurities and wear. It is a popular material for wedding rings and jewelry because it is durable and less prone to scratching than other precious metals. Platinum gives jewelry an elegant and sophisticated look and is particularly sought after because it is rare and more expensive than gold.&amp;nbsp;&amp;nbsp; 
     
 Example of the use of platinum in the jewelry industry.  Here rings made of platinum and yellow gold.  
 However, the price of platinum is lower than that of gold. Why is it still more expensive?&amp;nbsp; 
 Although the price of platinum is generally lower than the price of gold, it is still more expensive because it is rarer and more difficult to mine than gold. Platinum deposits are less common and more difficult to extract than gold deposits, which increases the cost of mining. In addition, the demand for platinum as a jewelry and investment metal is high, which also influences the price. All these factors mean that platinum is more expensive than gold, despite its lower price per ounce.&amp;nbsp; 
 Hm, not quite conclusive. Is platinum jewelry possibly more expensive than gold jewelry due to the difficult processing?&amp;nbsp; 
 Yes, platinum is indeed more difficult to work with than gold due to its hardness and density. This means that more time and special skills are required to make platinum jewelry. This results in a higher cost to produce platinum jewelry, which affects the final price. As platinum is rarer and harder than gold, it is also more durable and stays in good condition for longer, which many customers appreciate and are willing to pay a higher price for.&amp;nbsp; 
 What about the specific weight of platinum? It weighs significantly more than gold for the same volume!&amp;nbsp; 
 That is correct. The specific weight of platinum is higher than that of gold. This means that an equal amount of platinum has a higher weight than an equal amount of gold. The specific weight of platinum is 21.45 g/cm³, while that of gold is 19.3 g/cm³. Therefore, a piece of jewelry of the same size made of platinum weighs more than a piece of the same size made of gold. This is another reason why platinum jewelry can be more expensive than gold jewelry.&amp;nbsp;&amp;nbsp; 
 Why is platinum jewelry and platinum wedding rings so popular with bridal couples and jewelry enthusiasts?&amp;nbsp; 
 Platinum jewelry and platinum wedding rings are popular with bridal couples and jewelry enthusiasts because of their hardness, density, beauty and durability. 
 
 
 Durability: Platinum is a very robust and durable metal that is less susceptible to scratches and wear than other metals. This makes it a good choice for wedding rings and jewelry that are meant to last. 
 
 
 Elegance: Platinum has a shiny, white color that looks particularly elegant and sophisticated. It gives pieces of jewelry a high-quality look and goes well with diamonds and other precious stones. 
 
 
 Rarity: Platinum is a rare and sought-after metal that is more expensive than gold. Many customers appreciate its rarity and are prepared to pay a higher price for platinum jewelry. 
 
 
 Appreciation: Platinum is a precious metal that can increase in value over time. It is a good choice for investors and collectors. 
 
 
 Overall, platinum offers a combination of longevity, elegance, rarity and appreciation that makes it a popular choice for wedding rings and jewelry.

                 Historical facts about palladium: 
 discovered in 1803 by William Hyde Wollaston, he named palladium after the asteroid Pallas. 
 He found it in South African platinum ore in samples obtained by dissolving it in aqua regia. Metallic  palladium  and alloys containing palladium come from the Urals, North and South America, Ethiopia and Australia. However, they have been exploited there, but are still extracted from nickel and copper ores. in contrast to silver, for example, palladium does not react with oxygen, i.e. it does not tarnish. If palladium is cold-formed, for example in the manufacture of&amp;nbsp;  Mokume Gane wedding rings  &amp;nbsp;palladium is much more reactive than the related element platinum, but still belongs to the precious metals. It dissolves in nitric acid. It dissolves slowly in hydrochloric acid with the addition of air. The precious metal character of palladium is comparable to that of silver, a neighboring element in the periodic table. It is the more noble metal in many acids. In hydrochloric acid, however, it is the less noble metal. 
 What is palladium actually? 
 Palladium is a chemical element with the symbol Pd and atomic number 46. It belongs to the platinum metals and is used in the jewelry and electronics industries as well as in automotive catalysis.&amp;nbsp; 
 How is palladium extracted&amp;nbsp; 
 Palladium is extracted from nickel and copper ores using a combination of pyrometallurgical and hydrometallurgical processes. The first step is to smelt and refine the ore to separate the palladium. It is then extracted in a pure form.&amp;nbsp; 
 What special properties does palladium have&amp;nbsp; 
 Palladium has the following special properties: 
 
 
 Low density: palladium is the sixth densest metal and has a lower density than platinum. 
 
 
 High corrosion resistance: It is resistant to corrosion and oxidation, which makes it ideal for applications in the electronics and jewelry industry. 
 
 
 Catalytic properties: Palladium is an excellent catalyst and is used in automotive catalysis and petrochemicals. 
 
 
 Good electrical conductivity: It has good electrical conductivity and can be used as a conductor in electronic devices. 
 
 
 Good thermal conductivity: Palladium also has good thermal conductivity, which makes it suitable for applications in high temperatures. 
 
 
 What role does palladium play in the jewelry industry&amp;nbsp; 
 In the jewelry industry, palladium plays an important role due to its following properties:&amp;nbsp; 
 
 
 Hypoallergenic: It is hypoallergenic and is therefore suitable for people with nickel allergies who may be allergic to other jewelry metals such as gold or white gold. 
 
 
 Bright appearance: Palladium has a bright, white appearance that is comparable to platinum. 
 
 
 Tough: It is robust and corrosion resistant, making it ideal for use in jewelry such as rings, necklaces and bracelets. 
 
 
 Easy to work with: It is easy to work with and can therefore be molded into different shapes and designs. 
 
 
     
 Example of the    Use of palladium    in contrasting wedding rings, together with    Silver.    
 Isn&#039;t palladium mainly used for jewelry alloys such as white gold?&amp;nbsp; 
 Yes, that is true. Palladium is often used for jewelry alloys such as white gold. It is combined with other metals such as gold, nickel or copper to create an alloy with specific properties. The addition of palladium, for example, improves the corrosion resistance and the bright appearance of the alloy. White gold jewelry alloyed with palladium often has better durability and a bright, white appearance similar to platinum.&amp;nbsp; 
 However, nickel has been banned since 1982 and is subject to a declaration requirement. Therefore, nickel is no longer used in jewelry alloys.&amp;nbsp; 
 That&#039;s right, thanks for pointing that out. Nickel has indeed been banned in the EU since 1982 and is subject to identification if it comes into contact with skin. It is therefore no longer used in many jewelry alloys, especially in Europe. Instead, alternative alloys are used that are hypoallergenic and meet customer requirements. 
 Isn&#039;t palladium predominantly used here instead of nickel to alloy white gold?&amp;nbsp; 
 Yes, that is correct. Palladium is used instead of nickel in many white gold jewelry alloys because it is hypoallergenic and has a bright, white appearance. The addition of palladium also improves the robustness and corrosion resistance of the alloy. Therefore, it is a popular alternative to nickel in white gold jewelry alloys. 
 Well, not only an alternative, but nickel is no longer used in jewelry alloys in Europe, but at least not in Germany.&amp;nbsp; 
 Thank you for pointing this out. You are absolutely right, nickel is no longer used in jewelry alloys in Europe, including Germany, because it is banned and requires identification if it comes into contact with skin. Instead, palladium is often used in white gold jewelry alloys to create hypoallergenic and robust pieces of jewelry

                 What actually is &quot;green gold&quot; or &quot;green gold&quot;? 
 If you search for green gold on Google, you will notice that the precious metal alloy with a slightly greenish shimmering color can be found here. On the other hand, the term green gold now also seems to be used with the term &quot;green gold&quot; in the sense of fair trade gold. Interestingly, CBD products, i.e. dietary supplements made from hemp or cannabis, are also referred to as &quot;green gold&quot;. 
 Green gold looked up on Wikipedia 
 Green gold is a greenish-yellow gold alloy with no added copper. 
 The color is created by approximating the atomic ratio of gold : silver 1:1, which in the best case corresponds to a gold content of 646, at which the clearest shade of green occurs. As the silver content in this case is already over 40 %, the color is relatively light. Up to a third of the silver can be replaced by cadmium, which intensifies the green tone but reduces the favorable tarnishing properties and the melting temperature. The alloys are very soft and not very strong in color. Green gold is rarely used, usually e.g. to depict foliage or similar. 
  Today I asked the OpenAI about green gold 
  ... and got contradictory statements to Wikipedia.  
  Namely:  Green gold is an alloy of gold and copper, so named because of its green color. The alloy is often used in jewelry applications because it is more resistant than pure gold and has a unique color. The exact composition of green gold can vary, but it usually consists of 75-85% gold and 15-25% copper. 
  Here is the AI&#039;s response regarding toxic components in green gold 
 Yes, in some cases toxic metals such as cadmium or lead may be present in green gold alloys. To ensure that you are not getting toxic metals, you should buy green gold jewelry from a reliable manufacturer who performs regular tests to guarantee the quality and safety of the jewelry. 
 What does master goldsmith Markus Wiesner and the jewelry industry know about green gold? 
 First a few characteristics: 
 
 Unsatisfactory green color 
 slightly stronger color with toxic additional metals 
 Rather unattractive as a single jewelry color 
 If then as a contrasting color in e.g. Mokume Gane wedding rings 
 
 If only gold and silver are alloyed, as described in Wikipedia, the result is a &quot;soft&quot; precious metal alloy. Its properties must therefore be improved by adding copper. Incidentally, this applies to almost all gold alloys used in the jewelry industry and by goldsmiths.

                 Fine gold: The pure gold in jewelry making 
 Gold, a symbol of wealth and stability, has a long and fascinating history in human history. Fine gold in particular, which is almost pure gold, plays an important role in jewelry making. This article sheds light on the properties, use and special features of fine gold and gold alloys in the jewelry industry. 
 What is fine gold? 
 Fine gold is gold in its purest form, with a purity of 999.9 parts per thousand or 24 carats. It is virtually free of other metals, which gives it an incomparable purity and radiant shine. Due to its softness, fine gold is rarely used on its own for jewelry, but usually in the form of alloys to increase its hardness and resistance. 
 History and alloys of gold 
 The importance of gold alloys 
 Gold alloys consist of gold mixed with other metals such as silver and copper. These alloys are necessary to improve the mechanical properties of gold, as pure gold is too soft to be used for jewelry that is in daily use. 
 Until the 19th century, it was forbidden to alloy gold with other metals in Europe. It was only later that gold, silver and copper were used together, as these metals often occur together in nature. This three-metal system has established itself as the standard for classic jewelry alloys and is still used today. 
 Variety of colors through alloys 
 By combining gold with silver and copper, different shades of color can be created. Here are a few examples: 
 
  Rich yellow : This classic color is achieved through a balanced mixture of gold, silver and copper, as in the Mokume Gane wedding rings Abura. 
  Light green : A higher proportion of silver creates a greenish hue.  Green gold.  
  Salmon pink : A higher proportion of copper produces a reddish or pinkish hue. 
  Silver white : With a very high proportion of silver, a whitish shade is achieved. 
 
 In addition, the properties of the alloys can be further influenced by the addition of other metals such as palladium or nickel, depending on the requirements. 
 Fineness of gold alloys 
 The fineness of gold alloys is given in parts per thousand and describes the proportion of pure gold in the total weight of the alloy. Common finenesses in jewelry production are 
 
  333 : Contains 33.3% gold, often used in industrially manufactured jewelry. 
  585 : Contains 58.5% gold, a common alloy for high-quality jewelry. 
  750 : Contains 75% gold, often used for luxury jewelry. 
  999 : Pure gold or fine gold, rarely used on its own, but important for special applications and investments. 
 
 In Germany, jewelry and equipment may be alloyed and offered in any gold purity. The stamping of the fineness is not mandatory, but in the case of stamping, the legal regulations must be observed. The exact fineness can only be determined by laboratory analysis. In everyday life, a random sample is often used to determine the approximate fineness. 
 Use of fine gold in jewelry production 
 Mokume Gane technique 
 A special application of gold alloys, including fine gold, is the  mokume gane technique . This traditional Japanese forging technique creates unique patterns reminiscent of wood grains. Mokume Gane wedding rings, such as the Abura rings, use the variety of colors and properties of different gold alloys to create stunning and individual pieces of jewelry.  More about Mokume Gane . 
 Wedding rings and engagement rings 
 Fine gold is often used in wedding bands and engagement rings, either alone or in alloys, to ensure the durability and resistance of the jewelry. The warm, yellow color of gold symbolizes love, constancy and prosperity, making it perfect for these meaningful pieces of jewelry. 
 Luxury jewelry 
 750 gold is often used for luxury jewelry as it offers an excellent balance between purity and durability. This alloy is ideal for elaborate designs and pieces of jewelry that require a high fineness to emphasize the luxurious character.

In Japan, the term shakudo is derived from the words ‘Shaku’ meaning ‘to make’ and ‘Do’ meaning ‘copper’. Since its creation many centuries ago, it has been used to create beautiful pieces of art ranging from jewelry to sculptures. The history of shakudo can be traced back to the Edo period in Japan (1603-1868). At this time, it was mainly used by samurai warriors as decoration on their armour and swords. The metal was highly valued by the elite classes due to its strong tonal qualities, which were believed to have spiritual powers. As a result, shakudo became increasingly popular among those who sought good fortune and luck. The use of shakudo in crafts also began to spread beyond samurai circles during the Edo period. Artisans began using this metal alloy to create intricate works of art such as statues and jewelry. They took advantage of its ability to take on different colours when mixed with other metals, resulting in a beautiful range of tones from light blues to deep purples. Today, shakudo is still being used for decorative purposes but also for practical applications such as medical implants and electrical components. The tonal qualities that made it so popular centuries ago are still admired today, often being referred to as &#039;shakudo&#039;s persuasive tonality&#039;. Its enduring popularity makes shakudo one of the oldest metals still being used in art today.    
 
 
 
 
    3. The benefits of Shakudo    
 
 
 
 
    Tonality Shakudo tonality is a technique used in Japanese metalwork and is known for its beauty and elegance. The art of Shakudo was first developed during the Edo period, when craftsmen used copper and gold alloy to create intricate designs on armour, swords, and other metal goods. This method of working with metals has since been adopted by modern craftsmen and jewellers to create unique pieces with stunning visual appeal. The use of Shakudo tonality can be traced back to the ancient practice of using different metals to create contrasting colours. By combining copper and gold alloys, craftsmen were able to achieve subtle colour variations that could be used to create beautiful patterns and designs. This allowed them to create art with a range of shades from dark blues through to light yellows - giving each piece an individualistic appearance. Today, Shakudo tonality is still widely used by jewellers for its unique aesthetic qualities. It can be used to add depth and texture to a piece, making it appear more striking than if it had been made with only one metal. The technique also provides an interesting contrast between two or more metal tones - creating a subtle yet eye-catching effect. In addition to its visual appeal, Shakudo tonality also offers persuasive tonality advantages. By combining different metals in various ways, the pieces created will have their own unique sound qualities - whether they are intended as musical instruments or simply decorative objects. This means that any piece created using this technique will have its own distinctive voice - one which can draw the attention of listeners or viewers alike. For these reasons, Shakudo tonality is increasingly being used by contemporary jewellers who are looking for something special in their creations. Not only does it provide a captivating visual appeal but also adds an extra layer of persuasive tonality that can easily draw people in. With so many benefits, it’s easy to understand why this centuries-old technique continues to be so popular today!    
 
 
 
 
    4. How to care for your Shakudo jewelry    
 
 
 
 
    Shakudo jewelry is made with a unique alloy that gives it a beautiful, deep blue colour. The metal is very soft and delicate, so it&#039;s important to take special care when cleaning and storing your Shakudo jewelry. Here are some tips on how to keep your Shakudo jewelry looking its best: - Avoid exposing your Shakudo jewelry to harsh chemicals or cleaners. Stick to using mild soap and water to clean your jewelry. - When you&#039;re not wearing your Shakudo jewelry, store it in a soft, dry place. A good option is a lined jewelry box or pouch. - Be careful not to scratch or damage your Shakudo jewelry. The metal is quite soft, so it&#039;s easy to accidentally scratch it. If you do scratch your jewelry, you can try buffing out the scratch with a soft cloth.    
 
 
 
 
    5. Why Shakudo is the perfect gift    
 
 
 
 
    Shakudo is a beautiful metal that looks like gold but has a subtle blue undertone. It&#039;s perfect for anyone who loves the look of gold but wants something a bit different. It&#039;s also a great gift for someone who loves Japanese culture or is interested in trying out a new metal.

                <![CDATA[
                 Wiesner Mokume Gane Trauringe verwendet Recycling Gold. 
 Bereits seit 15 Jahren kaufen wir direkt in unserer Goldschmiede mehr Altschmuck, Barren und Münzen an, wie wir eigentlich für unsere Trauringproduktion benötigen. Aus diesem Grund sprechen wir von 100% Recycling Gold und Silber in unserer Fertigung. Da dem Thema Recycling manchmal der Mythos von schlechterer Qualität anhaftet, möchten wir nachfolgend darüber aufklären, warum Recyclinggold primär die gleiche Qualität, bei genauem hinsehen, sogar eine höhere Qualität besitzt. (Bei Einbezug von Umwelt und sozialen Faktoren) 
 Zunächst: Welche Mythen kursieren über Recycling Gold&amp;nbsp; 
 ❌Mythos 1: Recyceltes Gold ist minderwertig. ✔️Fakt: Recyceltes Gold durchläuft rigorose Raffinationsprozesse, die seine Qualität sicherstellen. Es ist chemisch und physisch nicht von neu gewonnenem Gold zu unterscheiden.  ❌Mythos 2: Recyceltes Gold ist nicht wirklich nachhaltig ✔️Fakt: Die Verwendung von recyceltem Gold reduziert den Bedarf an neuem Goldabbau, der oft mit erheblichen ökologischen und sozialen Kosten verbunden ist. Bei Wiesner Trauringe verwenden wir 100% recyceltes Gold, was zu kurzen Transportwegen, lokaler Wertschöpfung und weniger CO2-Emissionen führt.  ❌Mythos 3: Recyceltes Gold ist nur für &quot;einfache&quot; Schmuckstücke geeignet ✔️Fakt: Die Qualität von recyceltem Gold ermöglicht seine Verwendung in allen Arten von Schmuck, einschließlich hochwertiger Trauringe und Verlobungsringe. 
   Die Fakten sprechen klar für recyceltes Gold 
 Es ist qualitativ hochwertig, umweltfreundlicher und wirtschaftlich sinnvoll. Bei Wiesner Mokume Gane Trauringe ist die Verwendung von 100% recyceltem Gold und Silber nicht nur eine Wahl, sondern ein klares Bekenntnis zu Nachhaltigkeit und erstklassiger Qualität. 
  Goldene Zeiten für die Umwelt: Die Vorteile von Recycling Gold in Trauringen  
 In der rasanten Welt der Mode und des Konsums ist die Nachfrage nach Edelmetallen, insbesondere Gold, kontinuierlich gestiegen. Ein glänzender Star inmitten dieser Szene ist das &quot;Recycling Gold&quot;. Vor allem, wenn es um etwas so Wertvolles und Symbolisches wie Trauringe geht, stellt sich oft die Frage nach der Herkunft und Qualität des Goldes.&amp;nbsp; 
  1. Qualitätsgarantie von Recycling Gold  
 
 
  Die Wahrheit hinter dem Mythos: &amp;nbsp;Ein weit verbreiteter Irrglaube ist, dass recyceltes Gold minderwertig ist. In Wahrheit durchläuft recyceltes Gold strenge Raffinationsprozesse, die sämtliche Verunreinigungen beseitigen. Das Resultat? Gold, das in Qualität und Reinheit neu gewonnenem Gold in nichts nachsteht. 
 
 
  Recycling Gold in Trauringen: &amp;nbsp;Die makellose Qualität von recyceltem Gold macht es zur idealen Wahl für Schmuckstücke, die ein Leben lang getragen werden sollen, wie Eheringe und Trauringe. Die Beständigkeit und Langlebigkeit von Recycling Gold steht außer Frage. 
 
 
  2. Der ökologische Fußabdruck von Gold  
 
 
  Nachhaltigkeitsfaktor: &amp;nbsp;Ein bedeutender Vorteil von recyceltem Gold ist seine positive Auswirkung auf die Umwelt. Indem der Bedarf an neuem Goldabbau reduziert wird, werden erhebliche ökologische und soziale Kosten vermieden. 
 
 
  CO2-Emissionen und Goldabbau: &amp;nbsp;Der primäre Goldabbau hat mehrere umweltbelastende Aspekte, von der Entwaldung über erheblichen Energieverbrauch bis hin zur Verwendung schädlicher Chemikalien. Laut einigen Studien kann der Abbau von nur einem Gramm Gold bis zu 1.000 Gramm CO2 freisetzen. Im Gegensatz dazu liegt der CO2-Fußabdruck beim Recycling von Gold wesentlich niedriger. 
 
 
  Lokale Wertschöpfung: &amp;nbsp;Neben den ökologischen Vorteilen fördert die Verwendung von Recycling Gold auch die lokale Wirtschaft, indem Transportwege verkürzt und CO2-Emissionen reduziert werden. 
 
 
  3. Vielseitige Anwendungen von Recycling Gold  
 
 
  Nicht nur für &quot;einfachen&quot; Schmuck: &amp;nbsp;Ein weiterer Mythos ist die Annahme, dass recyceltes Gold nur für weniger aufwändige Schmuckstücke geeignet sei. In Wahrheit ist Recycling Gold genauso vielseitig und anwendbar wie neu gewonnenes Gold – ob für prachtvolle Halsketten, elegante Ohrringe oder symbolträchtige Eheringe. 
 
 
 &amp;nbsp; 
  Welche sozialen und ökologische folgen hat oft der Abbau von Gold in herkömmlichen Minen.  
 Der Abbau von Gold, insbesondere in Entwicklungsländern, hat erhebliche soziale und gesundheitliche Auswirkungen auf die Arbeiter und die Gemeinschaften in der Umgebung der Minen sowie auf die Umwelt. Hier sind einige der wichtigsten Punkte: 
  1. Gesundheitliche Risiken für Arbeiter:  
 
 
  Gefährliche Arbeitsbedingungen: &amp;nbsp;Viele Goldminen, insbesondere kleinere, nicht regulierte, haben unsichere Arbeitsbedingungen. Einstürzende Minen, fehlende Schutzausrüstung und unsachgemäßer Umgang mit Maschinen können zu Verletzungen oder gar zum Tod führen. 
 
 
  Exposition gegenüber Chemikalien: &amp;nbsp;Die Goldgewinnung erfordert oft den Einsatz von hochgiftigen Chemikalien wie Quecksilber und Zyanid. Bei unsachgemäßer Handhabung können diese Chemikalien schwere gesundheitliche Probleme verursachen, darunter neurologische Schäden, Atemwegserkrankungen und Fortpflanzungsprobleme. 
 
 
  Langzeiteffekte: &amp;nbsp;Viele Arbeiter in Goldminen sind chronischen Gesundheitsproblemen ausgesetzt, die sich über Jahre hinweg entwickeln, beispielsweise durch das Einatmen von Staub oder den dauerhaften Kontakt mit giftigen Chemikalien. 
 
 
  2. Soziale Auswirkungen:  
 
 
  Ausbeutung und Kinderarbeit: &amp;nbsp;In vielen Minen, besonders in nicht regulierten Bereichen, sind Kinderarbeit und die Ausbeutung von Arbeitern weit verbreitet. Die Bezahlung ist oft minimal und reicht kaum zum Überleben. 
 
 
  Enteignung und Vertreibung: &amp;nbsp;Der Goldabbau kann zur Vertreibung lokaler Gemeinschaften führen, wenn ihr Land für den Bergbau benötigt wird, oft ohne angemessene Entschädigung oder Berücksichtigung der Rechte indigener Völker. 
 
 
  Soziale Spannungen: &amp;nbsp;Der Zustrom von Arbeitern und das schnelle Wachstum von Bergbaustädten kann zu sozialen Spannungen, erhöhten Kriminalitätsraten und anderen sozialen Problemen führen. 
 
 
  3. Umweltauswirkungen vor Ort:  
 
 
  Wasserverschmutzung: &amp;nbsp;Die Verwendung giftiger Chemikalien, insbesondere Zyanid und Quecksilber, kann zu schwerer Wasserverschmutzung führen, die sowohl die Tierwelt als auch die menschliche Gesundheit beeinträchtigt. 
 
 
  Entwaldung: &amp;nbsp;Große Waldgebiete werden oft gerodet, um Platz für Minen zu schaffen, was zum Verlust von Biodiversität und zum Bruch des natürlichen Wasserhaushalts führt. 
 
 
  Bodenverschmutzung: &amp;nbsp;Der Abbau hinterlässt oft riesige Mengen an Abraum und Abfall, die den Boden verschmutzen und für die Landwirtschaft unbrauchbar machen. 
 
 
  Eingriffe in den natürlichen Wasserfluss: &amp;nbsp;Der Bergbau kann den natürlichen Wasserfluss stören, wodurch Gemeinschaften stromabwärts von ihrer Wasserquelle abgeschnitten werden können. 
 
 
 Die Nachfrage nach ethisch gewonnenem Gold und das Bewusstsein für diese Probleme nehmen zu, und viele Organisationen und Unternehmen setzen sich für einen verantwortungsbewussteren Goldabbau ein. Das Recycling von Gold kann dabei eine entscheidende Rolle spielen, indem es den Bedarf an neuem Goldabbau reduziert und die damit verbundenen sozialen und umweltbezogenen Probleme vermindert. 
 &amp;nbsp; 
  Wie ist denn die Faktenlage dazu, dass die Arbeiter in den Minen immerhin eine Arbeit haben, und sonst evtl. Hunger leiden würden?  
 Es ist eine komplexe Angelegenheit, die sowohl ethische als auch wirtschaftliche Fragen aufwirft. Hier sind einige Fakten und Perspektiven, die das Dilemma rund um die Arbeit in Minen in Entwicklungsländern beleuchten: 
  1. Wirtschaftliche Notwendigkeit:  
 
 
  Einkommensquelle: &amp;nbsp;Für viele Menschen in Bergbauregionen ist die Arbeit in Minen oft die einzige verfügbare Einkommensquelle. In einigen Fällen können diese Jobs besser bezahlt sein als andere verfügbare Arbeiten, vor allem in Gebieten mit wenigen wirtschaftlichen Alternativen. 
 
 
  Wirtschaftlicher Beitrag: &amp;nbsp;Der Bergbau kann einen bedeutenden Anteil am Bruttoinlandsprodukt (BIP) einiger Länder haben. Dies bedeutet, dass die Wirtschaft und die öffentlichen Finanzen des Landes von den Einnahmen aus dem Bergbau profitieren können. 
 
 
  2. Qualität der Arbeitsplätze:  
 
 
  Arbeitsbedingungen: &amp;nbsp;Auch wenn die Minenarbeit eine Einkommensquelle bietet, sind die Arbeitsbedingungen oft prekär. Unsichere Arbeitsumgebungen, lange Arbeitszeiten und fehlende Schutzausrüstung sind häufige Probleme. 
 
 
  Temporäre Natur der Arbeit: &amp;nbsp;Minen haben oft eine begrenzte Lebensdauer. Wenn sie erschöpft sind, werden sie geschlossen, und die Arbeitsplätze verschwinden, was zu wirtschaftlichen Herausforderungen für die Arbeiter und ihre Gemeinschaften führt. 
 
 
  3. Abhängigkeit und Vulnerabilität:  
 
 
  Mangel an Diversifizierung: &amp;nbsp;Eine übermäßige Abhängigkeit von der Bergbauindustrie kann problematisch sein, insbesondere wenn es keine Bemühungen gibt, die Wirtschaft zu diversifizieren. Wenn der Bergbausektor durch externe Faktoren wie fallende Weltmarktpreise betroffen ist, kann dies zu wirtschaftlichen Krisen führen. 
 
 
  Soziale Probleme: &amp;nbsp;Der Zustrom von Arbeitern in Bergbaugemeinschaften kann zu sozialen Spannungen und erhöhten Kriminalitätsraten führen. Außerdem können lokale Gemeinschaften von ihrem Land vertrieben werden, um Platz für Bergbauaktivitäten zu schaffen. 
 
 
  4. Langfristige Perspektive:  
 
 
  Brauchen wir einen Paradigmenwechsel? &amp;nbsp;Einige argumentieren, dass eine kurzfristige Abhängigkeit vom Bergbau akzeptabel ist, wenn die Einnahmen dazu verwendet werden, langfristige Entwicklungsziele zu fördern und eine diversifizierte Wirtschaft aufzubauen. 
 
 
  Ethik vs. Wirtschaft: &amp;nbsp;Es ist ein Balanceakt zwischen der Anerkennung der wirtschaftlichen Vorteile des Bergbaus und der Notwendigkeit, ethische Fragen der Arbeitsbedingungen und Umweltauswirkungen anzusprechen. 
 
 
 Es ist wichtig zu erkennen, dass während die Bergbauindustrie Arbeitsplätze bietet und in vielen Fällen eine wesentliche Einkommensquelle für viele Menschen darstellt, die Arbeitsbedingungen und langfristigen Auswirkungen auf die Gemeinschaften und die Umwelt nicht ignoriert werden sollten. Eine umfassende, auf Nachhaltigkeit ausgerichtete Herangehensweise ist notwendig, um sicherzustellen, dass die Vorteile des Bergbaus die damit verbundenen Kosten überwiegen. 
 &amp;nbsp; 
  Verschiedene Organisationen, die etische und nachhaltige Praktiken in Schmuckindustrie fördern  
 Ja, es gibt verschiedene Organisationen und Initiativen, die darauf abzielen, ethische und nachhaltige Praktiken in der Schmuck- und Edelmetallindustrie zu fördern. Eine prominente Organisation ist der&amp;nbsp; Responsible Jewellery Council (RJC) . Es ist zu beachten, dass es keinen &quot;European Jewellery Council&quot; gibt, aber der Responsible Jewellery Council ist eine internationale Organisation, die Standards für die gesamte Schmucklieferkette festlegt, von der Mine bis zum Einzelhandel. 
  Responsible Jewellery Council (RJC):  
 
 
  Ziele: &amp;nbsp;Der RJC wurde gegründet, um verantwortungsvolle ethische, soziale und ökologische Praktiken in der Schmucklieferkette zu fördern. Dies beinhaltet auch die Gewinnung von Edelmetallen und Diamanten. 
 
 
  Zertifizierung: &amp;nbsp;Der RJC bietet ein Zertifizierungsprogramm für seine Mitglieder an, das auf dem RJC-Code of Practices basiert. Dieser Code legt Standards für Geschäftspraktiken, Menschenrechte, Arbeitsrechte, Umweltbelange und Managementpraktiken fest. 
 
 
  Transparenz: &amp;nbsp;Einer der Hauptvorteile der RJC-Zertifizierung ist die Transparenz. Unternehmen, die sich zertifizieren lassen, müssen unabhängige Audits durchführen lassen, um sicherzustellen, dass sie die festgelegten Standards einhalten. 
 
 
  Anerkennung: &amp;nbsp;Der RJC wird von vielen großen Unternehmen in der Schmuckindustrie sowie von NGOs und anderen Stakeholdern anerkannt und unterstützt. 
 
 
 Es ist wichtig zu beachten, dass während Zertifizierungen wie die des RJC dazu beitragen können, höhere Standards in der Industrie durchzusetzen, sie nicht alle Probleme im Zusammenhang mit der Goldgewinnung und der Schmuckproduktion beseitigen. Verbraucher, die ethisch produzierte Schmuckstücke kaufen möchten, sollten sich über die Zertifizierungen und die Praktiken der Unternehmen informieren und gegebenenfalls weitere Fragen stellen, um sicherzustellen, dass ihre Käufe mit ihren Werten übereinstimmen.

                 What actually is Shibuichi 
   
 An artfully crafted mokume gane ring with shibuichi and copper. 
 Shibuichi is a traditional Japanese alloy that is mainly used in the manufacture of art and jewelry. It consists of a mixture of silver and copper and can be further refined by gold plating or patination. The origins of this technique date back to the Nara period in the 7th century. Although Shibuichi was used in the manufacture of    Mokume gane rings   &amp;nbsp;, it is worth taking a look at this fascinating material. 
 Who invented shibuichi and when? 
 &quot;Shibuichi is not the work of one person, but the result of centuries of experience and dedication.&quot; 
 The origins of Shibuichi cannot be attributed to a specific person or a specific point in time. Rather, the alloy was created over the course of centuries through the continuous development of Japanese craftsmanship. Shibuichi was first used as early as the Nara period - since then it has been part of the permanent repertoire of traditional Japanese craftsmen. 
 What role does shibuichi play in handicrafts 
  An elegant choker made from mokume gane with shakudo, silver and copper. 
 Shibuichi has been used in Japanese art for centuries to make precious objects such as sword fittings, caskets and tea vessels. It is particularly valued for its ability to produce subtle color nuances, which are created through targeted patination. Over time, a natural, darker patina develops, giving the material a special depth and character. 
  Did you know?   The name &quot;Shibuichi&quot; translates as &quot;a quarter&quot; - originally this referred to the ratio of silver to copper (25% silver, 75% copper). 
 Today&#039;s artisans also like to use shibuichi. It is easy to work with and allows a wide range of color and texture effects thanks to different patination techniques. 
 What substances can it be stained with and what colors does this produce? 
 Shibuichi can be stained with various substances to achieve a wide range of color variations and patina effects. Here is an overview of common staining agents and the possible color results: 
 
  Hydrogen peroxide:  produces a greenish patina. 
  Salt:  produces blue to greenish tones. 
  Ammonia:  produces a reddish to brown patina. 
  Acetic acid:  produces brown discoloration. 
  Wine:  can produce reddish color nuances. 
 
  Note:  The color effect depends heavily on the environment, the metal mixture and the duration of the stain - therefore no two results are the same. 
 What was Shibuichi used for in the past and today? 
 Historically, shibuichi was mainly used in Japanese art and in the forging of luxury items. The alloy&#039;s diverse color properties were particularly appreciated in sword handles, fine vessels and small art objects. 
  Diogo Romeiro, a contemporary jewelry designer who uses Shibuichi in his creations. 
 Today, Shibuichi is experiencing a new heyday: in modern jewelry design, it is often used to create extraordinary pieces with surfaces full of character. The combination of old technology with contemporary design language makes the material particularly exciting for designers. 
 Does shibuichi also play a role in mokume gane? 
 Yes, Shibuichi is an important material in the Mokume Gane technique. This artistic Japanese method combines different metals in layers that are bonded together under pressure and then worked to create a marble-like structure. 
 In the Mokume Gane process, the interplay of metals and subsequent patination creates complex, lively textures. Shibuichi contributes to the depth and variety of colors here, especially through its ability to create a variety of patina effects during the staining process.

  Frequently asked questions  
 
 What exactly is mokume gane? 
      
 A beautiful example of mokume gane as a sophisticated pearl clasp. 
 Mokume gane is an artistic forging technique from Japan in which several layers of metal are fused together and worked in such a way that wood-like grains are created. The result: unique patterns that can never be reproduced exactly. This technique is traditionally used to make jewelry, knives and decorative works of art - and is also used in the production of  mokume gane rings . 
 Historical background 
 The roots of mokume gane go back to the 17th century. The technique was originally developed to create ornate decorations for katana sword handles. During the Edo period, Japanese blacksmiths perfected this method and used it to create not only weapons, but also pieces of jewelry that are both functional and aesthetically pleasing. 
 &quot;Mokume gane embodies the Japanese aesthetic of beauty in simplicity and imperfection - wabi-sabi in metallic form.&quot; 
 The technique reached its heyday in the 19th century. To this day, it is regarded as an expression of the highest level of precision craftsmanship and artistic sophistication. 
 Who invented this technique in Japan? 
 The exact origin is not clearly documented, but according to tradition, the blacksmith  Denbai Shoami  was one of the first to practice mokume gane in the 17th century. He lived during the Edo period and was known for his innovative spirit. Even though no reliable records exist, his works are still highly valued today and form part of many museum collections. 
 Mokume Gane outside Japan 
 Today, mokume gane is no longer just a Japanese phenomenon. The technique has experienced a renaissance in North America and Europe. Many goldsmiths, designers and artisans have reinterpreted mokume gane. The knowledge is passed on in workshops and at art academies - and finds its place in modern jewelry collections as well as in unusual knife blades or design objects. 
  Tip:  In Germany, Wiesner Schmuck is one of the leading addresses for mokume gane rings with unique design and precision craftsmanship.

The combination of different metals creates unique patterns - no two rings are the same. Mokume Gane rings are an expression of individuality and solidarity, making them ideal companions for a life together. 
 Precious metals for mokume gane wedding rings

                 The fascinating world of pearls 
 Introduction 
 Pearls have always been coveted pieces of jewelry that captivate with their natural beauty and elegance. These precious jewels are created in shells and have a fascinating history. In this article, we delve into the world of pearls and discover the different types of cultured pearls, their origins and unique characteristics. 
 Akoya pearls 
  Origin and creation:  
 Akoya pearls are classic cultured pearls that originated around 1900. These pearls are cultivated in saltwater mussels, particularly in the waters of Japan and China. During cultivation, a mother-of-pearl nucleus is implanted into the mussel, whereupon the mussel coats this foreign body with layers of mother-of-pearl. After around 3 to 4 years, a pearl with a nacre thickness of 0.8 to 1.2 mm has formed. 
  Properties and colors:  
 Akoya pearls are characterized by their mostly round shape, which is given by the insertion of mother-of-pearl spheres. They are available in various colors, including cream, gold, green-white and grey. However, the most expensive and sought-after color is white-rosé. Akoya pearls are cultivated in sizes up to 9 mm in diameter, with larger pearls being rare and therefore particularly valuable. 
 South Sea pearls 
  Origin and formation:  
 South Sea pearls are among the most expensive cultured pearls and are grown in the silver-lipped pearl oyster. These oysters are mainly found in the waters of the South Seas, particularly on the north coast of Australia. South Sea pearls are characterized by their impressive size and natural beauty. 
  Characteristics and colors:  
 The color of South Sea pearls varies from silver-gray to rose and gold to gray and black. These pearls are often cultivated in sizes over 10 mm, which makes them particularly rare and valuable. Due to their size and value, they are often processed as single pearls. 
 Keshi pearls 
  Origin and creation:  
 Keshi pearls are seedless saltwater cultured pearls that originate in Japanese waters as well as in the South Seas. These pearls are an accidental product of nature, as they are formed when implanted mother-of-pearl nuclei are shed by the mussel. The remaining particles are then encased in the shell&#039;s mantle. 
  Properties and colors:  
 Keshi pearls are characterized by their irregular, often bizarre shapes. They come in delicate natural colors such as grey, white, rose and gold. Each Keshi pearl is unique and has an individual shape, which makes them particularly attractive pieces of jewelry. 
 Freshwater pearls 
  Origin and creation:  
 Freshwater pearls are cultivated in freshwater mussels, particularly in China. They are cultivated in the Biwa pearl mussel, a relative of the well-known Biwa pearl from Japan. Due to environmental pollution, cultivation in Lake Biwa has no longer been possible since the 1980s, which is why most freshwater pearls now come from China. 
  Properties and colors:  
 Freshwater pearls are available in a variety of shapes and colors. They come in delicate natural colors such as white-rose, salmon-orange, golden-brown and grey. In addition to the seedless freshwater pearls, there are also those with a core, which are cultivated in sizes over 8 mm.

 History and economic significance of silver 
 Silver as a means of payment 
 In earlier times, silver was particularly important for the production of silver coins, which were used as a means of payment. Until 1871, silver coins, also known as thalers, were the predominant means of payment in Germany. This currency was backed by silver reserves. After that, the so-called silver standard was replaced by the gold standard. The reason for using silver as a means of payment was its low reactivity and high stability of value. These properties made it an ideal material for coins that were to remain in circulation for a long time. 
 The transition to the gold standard 
 With the introduction of the gold standard, silver lost its importance as a means of payment.
