Blue Goldstone Necklace

A blue goldstone gemstone in a sterling silver pendant set on an adjustable black leather necklace. When copper is added to molten glass, the copper crystallizes. Sometime during the early 1800's, an Italian monk was making glass at his monastery. He accidentally spilled some copper filings into his molten glass and goldstone was born. The recipe for making goldstone was kept secret by the monks, but was handed down through time.
