Amethyst is the best known and most valuable form of quartz. The light-to-dark purple 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. A single stone will often show color zoning—angular zones of light and dark colors.
