Gold & Purple Sandstone
****
Goldstone is actually a man-made glass! It is made from silica, copper oxide, and other metal oxides, which is heated, allowed to crystallize, and then cooled. It is during the heating process that the metallic copper crystals are formed
Goldstone is a type of glittering glass made in a low-oxygen reducing atmosphere. The finished product can take a smooth polish and be carved into beads, figurines, or other artifacts suitable for semiprecious stone, and in fact goldstone is often mistaken for or misrepresented as a natural material.
