Amethyst is a violet variety of quartz. Ancient Greeks wore amethyst and carved drinking vessels from it in the belief that it would prevent intoxification.Amethyst is a purple variety of quartz and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions. Amethyst occurs in primary hues from a light lavender or pale violet to a deep purple. Amethyst may exhibit one or both secondary hues, red and blue.
