Ametrine (natural bi-color Quartz) Datolite This attractive thumbnail specimen hostsAmetrine is the naturally occurring bi colored variety of Quartz that is only found at the Anahi Mine in Bolivia. Some material is marked as coming from Brazil, but in reality, the rough is sometimes shipped from Bolivia across the border (which is only about 40 km away) to be processed in Brazil. There is no reported discovery of Ametrine anywhere in Brazil, and the Bolivian Ametrine remains the best and frankly ONLY commercially available material
