Amethyst is the most well-known purple gemstone. It has been highly esteemed throughout the ages for its stunning beauty and legendary powers to stimulate, and soothe, the mind and emotions. Amethyst ranges in hue from pale red-violet to deep violet, and can be transparent or opaque. It is also sometimes layered with white Quartz, which is known as Chevron Amethyst. Throughout history the special virtue of Amethyst has been that of preventing drunkenness and overindulgence. Ancient Greeks and Romans routinely studded their goblets with Amethyst believing wine drunk from an Amethyst cup was powerless to intoxicate. Catholic bishops also wore Amethyst in a ring to protect from mystical intoxication. Kissing the ring kept others from similar mystical intoxication and kept them grounded in spiritual thought. Whether its crystals are left natural, polished as tumblestones or faceted, Amethyst is a gem whose beauty transcends its commonality. It is actually a variety of Quartz and is found in many locations around the world.
