About

Crystals from Bolivia Bolivia is the world's only natural source of ametrine — a remarkable quartz variety where amethyst and citrine occur together in a single crystal, with purple and golden zones meeting in sharp geometric boundaries. All natural ametrine comes from the Anahi Mine in eastern Bolivia, which has been producing gem-quality material since the 17th century. The mine is located in the Pantanal wetlands region near the Brazilian border. Beyond ametrine, Bolivia produces deep-purple amethyst with exceptional clarity from mines in the eastern lowlands. The country's complex geology — spanning the Andes mountains, the Altiplano plateau, and ancient Precambrian shield rock — creates diverse mineralogical environments.
