Amethyst is a fine stone (formerly called half-precious stone), a violet variety of quartz. Its intense purple color is rare and sought after because most amethysts are very pale. These exceptional quality amethyst stones often originate in Brazil or Uruguay. It has a hardness of 7 on the Mohs scale.
Amethyst gets its name from its use against drunkenness and excess. In the past, it was sometimes used as a chalice to protect against possible poisoning attempts during banquets. It is the stone of the popes, symbolically representing spirituality and abstinence from vices.
