_ Amethyst, a transparent purple variety of quartz, is one of the most popular of the colored stones. In contemporary times, recognized as the birthstone of February, it was once believed to bring peace of mind to the wearer. It was also believed to prevent the wearer from getting drunk, and if the circle of the sun or moon was engraved thereon, it was believed to prevent death from poison.
Amethyst is available in shades from light to dark purple, it is relatively hard, fairly brilliant, and overall a good versatile wearable stone. Amethyst is available in good supply even in large sizes. Note that large sizes with deep color are becoming scarcer. Amethyst is probably one of the most beautiful stones available at a moderate price, although one must be careful because "fine" amethyst is being produced synthetically. Synthetic amethyst exhibits color zoning often looking like chevrons.
Amethyst may fade from heat and strong sunshine. Guard your amethyst from these conditions and it will retain its color indefinitely.
