About Amethyst
Amethyst is a purple variety of quartz, and probably the most recognizable and commonly collected mineral on earth.  Most amethyst comes from the prolific amethyst mines in Brazil, but can also be found in many other countries such as Mexico, China, Uruguay, USA, Turkey Canada, India, Zimbabwe, and more.   The color comes from iron impurities and natural radiation.  It can come in a wide variety of shades of purple, and can also occur with other associated minerals, notably calcite.  The incredible calcite and amethyst combos from Uruguay are, in our opinion, some of the most incredible mineral specimens to collect and treasure.  You can find multiple examples of amethyst in our online shop!
