Blue Goldstone 1x2mm Square Rondelle - 15-16 Inch Size_3-5mm one of the first fluorescentBlue 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.
