Amethyst is a type of quartz that owes its purple color to background radiation. The latter is primarily from the naturally occurring potassium-40 and members of the uranium and thorium decay series found in rocks and soil. For the radiation to turn quartz purple, the quartz must contain trace amounts of iron.
