Goldstone 4mm Microfaceted Round - 15-16 Inch Rocky Butte with red vinyl handlesGoldstone is a manmade material, consisting of opaque rust to 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.
