Blue Goldstone 8mm Round - 15-16 Inch R0445 potassium or bariumBlue Goldstone is an opaque, midnight blue glass with flecks of copper suspended within it. These flecks glitter as they catch the light and may appear white against the dark blue of the 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.
