Amber - The precious stone
Amber was formed up to 260 million years ago from viscous tree resin. Over the years, it became a solid substance. The name amber comes from the Low German börnen meaning to burn, as amber burns. Amber is very rarely found in the clear quality that is commercially available; this clarity is achieved by so-called clear boiling in rapeseed oil. This flushes out the trapped liquids, air bubbles and plant parts and the stone becomes clear. These stones are usually made into necklaces. However, amber pieces with enclosed insects or larger plant parts are also sought after. If you rub amber on a cloth, it becomes electrically charged and then attracts dust particles or even paper shreds. Even in ancient times, people took advantage of this property and used a large piece of amber as a clothes brush. The world's largest find site is in former East Prussia near Königsberg, now Kaliningrad. There are also large amber deposits on the bottom of the Baltic Sea. After a strong storm, you can certainly find one or the other amber washed up by the churning sea during a walk on the beach, for example on the island of Rügen. Today, amber is mostly processed into necklaces, rings, pendants or brooches.
