Variations of Amethyst
Through heating, Amethyst can produce Citrine, a beautiful yellow-hued quartz. Prasiolite, a green variation, is said to be found by hot springs, though it is most often created through the heating of Amethyst as well. Heat treatment at high temperatures, between 878 and 1382 degrees F, produce green, yellow, red, brown, or colorless varieties of Amethyst.
