Amethyst is a violet variety of quartz often used in jewelry. The name originates in Ancient Greece, where it was believed that the stone protected its owner from drunkenness. The ancient Greeks and Romans wore amethyst and made drinking vessels from it in the belief that it would prevent intoxication. It is one of several forms of quartz. Amethyst is also the traditional birthstone for February. We are offering a 3.75x5.75x2.25" deep specimen covered w/a layer of fine, lilac-colored amethyst crystals that have three large white calcite crystals scattered throughout, giving this specimen a spectacular contrast.
