Bolivian Ametrine: From
Mine to
Market by
GIA. Learn more about Bolivian ametrine from
Robert Weldon, GIA's photography and visual communications manager. He discusses the amethyst gemstone, the mines and the marketing of the gem. He also explains the rarity of Bolivian ametrine, and offers some personal insights about the time he spent in
Bolivia as a young man. Ametrine is
the rare and unique amethyst gemstone that is half amethyst (purple) and half citrine (yellow). Only 10 percent of Bolivian mined amethyst rock and amethyst crystals produce jewelry-quality ametrine. This video depicts the amethyst geode mine that is very difficult to access, and shows the amethyst rock and amethyst crystal mining process to produce amethyst gemstones. Robert Weldon offers a rare and valuable perspective on Bolivian ametrine, while shedding light on its unique gem-mining process.
