Green gold

What actually is "green gold" or "green gold"?

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 "green gold" in the sense of fair trade gold. Interestingly, CBD products, i.e. dietary supplements made from hemp or cannabis, are also referred to as "green gold".

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.

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's response regarding toxic components in green gold

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 "soft" 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.
