Amethyst is the best known and most valuable form of quartz. The color of natural amethyst is caused by iron or manganese compound impurities in the mineral and can range from a watercolor pale pink to a dark, almost opaque, purple. Named for the Greek word for “sober,” amethyst was believed to remedy drunkenness. As a crystal, amethyst is credited with relieving stress and promoting peace of mind. The emerald-cut has a rectangle shape and cut corners. Its facets are concentric planes that resemble stair-steps around the circumference of the gemstone, above and below the girdle.
