Green Goldstone 10mm Round - 15-16 Inch Skin with indigo being the mostGreen Goldstone is an opaque, almost black glass with flecks of copper suspended within it. These flecks glitter as they catch the light and appear green against the dark glass. Goldstone was first created during the Italian Renaissance when, as legend has it, a Venetian monk tipped molten copper into a vat of molten glass. When this combination crystallized, the result was glass permeated with thousands of tiny metallic sparkles.
