Origin: BRAZIL Pieces measure approximately 3.0" - 6.0" (AVERAGE SIZE) Amethyst is a violet gemstone that occurs when quartz containing significant iron impurities and other trace elements undergoes natural geological irradiation over long periods of time, altering the color. Color variations occur based on the amount of iron and the specific trace elements present in the original quartz. Handmade items vary in size, shape, and color when selected randomly (the highest quality items are chosen first). They'll be as beautiful as those in the photos.
