Rosarita Matched Cabochon Pair 20x26mm
Rosarita (also known as gold slag glass) is a rare man-made glass material created as a by-product of mid-20th-century gold smelting. Although it is frequently cut and polished for jewelry like a natural gemstone, it is actually silica-based glass infused with microscopic traces of gold that give it a vibrant red, orange, yellow or burgundy color.
