Amethyst is the most valuable variety of Quartz. It gets its violet color from irradiated iron impurities. You may have heard of other colors of Amethyst, but by definition, it can only be purple. When there is a higher iron content with hematite inclusions, it appears black. Pink Amethyst is simply a lighter lavender version. Green Amethyst is technically not an Amethyst but actually another type of quartz called Prasiolite. I can't honestly say how it ever became commonly known as Green Amethyst. Possibly, because its an easier name to remember than Prasiolite.
Amethyst derived its name from the Greek word "amethystos". The Greeks believed amethyst gems could prevent intoxication which is why many of their wine goblets were carved from the stone. Medieval European soldiers wore amethyst amulets as protection in battle in the belief that amethysts heal people and keep them cool-headed. Tibetans consider amethyst sacred to the Buddha and make prayer beads from it.
