The very first traces of marcasite were found in ancient Greece, during the Inca period and it is reported that Cleopatra herself used to favour this style of jewellrey! A royal theme continues with marcasite's popularity increasing throughout the 18th and 19th century, reaching a pinnacle during Queen Victorias reign where they were adorned by the queen herself. A perfect substitute for diamonds,marcasite jewellrey is normally a reference to iron pyrite, fools gold's silver toned twin. True marcasite itself is of the same composition as pyrite but is too brittle to be used within jewellrey, often crumbling to dust. Marcasite was also popular within the 1920's, often used within art deco designs. Theodo Fahrner was a renowned producer of sought after art deco pieces set with marcasite and other coloured stones. The factory was unfortunately bombed and destroyed during the second world war, along with the factory's historical archives, making details about his jewellrey hard to come by!
