GoldStone 10mm Round - 15-16 Inch R0968 and much of the blackGoldstone is a manmade material, consisting of opaque rust red glass with tiny flecks of glittering copper suspended within it. 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.
