Goldstone is a man-made colored glass that contains abundant, flat-faced, highly reflective inclusions. The reflective inclusions have a bright metallic luster, and their glittering appearance immediately attracts attention. This exciting appearance has made goldstone a popular man-made gem and sculptural material. It is often cut into cabochons, hearts, beads, spheres, pendulums, arrowheads, and small sculptures. It is a popular material for making tumbled stones.

Goldstone is produced in a variety of colors. Reddish brown, the original color, is the least expensive and the most commonly encountered variety of goldstone. Dark green, dark blue, and dark purple goldstone are also produced.
