The only significant source of natural ametrine is the Anahí mine, in eastern Bolivia, Santa Cruz, Bolivia, and employs about 70 workers at the mine site. It is the source of all the natural ametrine currently on the world's market. In the early days of production, there was much mis-information about the locality with Brazil and Uruguay frequently being mentioned as the source of ametrine. Citrine is a term applied to a variety of different quartzes that range from yellowish green to orange brown. These colors have a number of different origins. Some are due to changes brought about by exposure to naturally occuring gamma rays and some are due to minor differences in the chemical composition. The citrine color in Bolivian ametrine appears to come from the incorporation of very small aggregates in the form of a hydrous iron oxide. With this gem you will enjoy the best of both worlds amethyst and citrine combined If you have any questions please don't hesitate to contact me, thank you for your interest on this item Roberto   Place a Bid!
