Amethyst in Agate Geode with Calcite Crystal, Uruguay

Amethyst (SiO2) is a purple variety of quartz. The characteristic purple color is created when trace amounts of iron are irradiated (from the natural radiation in surrounding rock). Price is based upon three factors: weight, shape & color. This natural specimen has NOT been heat-treated, unlike artificially enhanced (Brazilian) amethyst; It was mined in the northern region of Uruguay’s Artigas Department, the premier source of fine quality amethyst. Metal Stand Included.
