Amethyst has a longhistory in lore and its name is derived from the Greek word amethystos whichtranslates to not drunk, as it was commonly believed in those days thatamethyst crystals can guard against drunkenness. As such, ancient Greeks oftencarved drinking vessels from large amethyst crystals.
This gem has lost someof its historical popularity in modern times, though as recently as the 18thand 19th centuries, amethyst was considered one of the most valuable anddesirable gems, worn by royalty and often included in expensive hautejoaillerie suites. Today, the light pinkish-lavender shades areextremely popular, which are referred to as Rose de France, and areoften favoured by artisan lapidaries to show off their cutting skills.
Though amethystcrystals are abundant, very clear, gem quality crystals with even colouring anda deep violet hue are not, and clear gems of this colour can fetch prices closeto a hundred dollars per carat. Amethyst has historically been prized by the CatholicChurch, featuring in many jewellery items worn by high church officials.
Amethyst is a variantof quartz, with iron atoms acting as the colouring agent. Other variants ofquartz include: ametrine, aventurine, citrine, prasiolite, rock crystal, rosequartz, rutilated quartz, smokey quartz & tigers eye.
