Edwardian 9ct Gold & Goldstone Round Pendant

621N
655 Admirers
Written by Olly Gerrish

A striking 9ct gold pendant that was made circa 1900. It has been set with a round goldstone. The manufacturing process for goldstone was invented in seventeenth-century Venice by the Miotti family, which was granted an exclusive license by the Doge. The most common form of goldstone is reddish-brown, containing tiny crystals of metallic copper that require special conditions to form properly. The initial batch is melted together from silica, copper oxide, and other metal oxides to chemically reduce the copper ions to elemental copper. The vat is then sealed off from the air and maintained within a narrow temperature range, keeping the glass hot enough to remain liquid while allowing metallic crystals to precipitate from solution without melting or oxidizing. Quite a process but what a beautiful result!
