Located in the jungle approximately 30 miles away from the border with Brazil and worked by a team of approximately 70 miners, the Anahi Mine is the premier locality for Ametrine, an unusual gemstone combining the rich purple and orange colors of the amethyst and citrine that give the stone its name.
Whereas pure quartz contains only silicon and oxygen, Ametrine derives its two-toned color from the segregated distribution of two separate iron ions in the crystal structure.
This crystal is predominantly amethystine in nature, though contains some areas of orange citrine. The main crystal is exceptionally distinct and stands freely above a secondary point. The Anahi mine is particularly notable for the size of its amethyst crystals, and this piece, is a clear example of why the location is so well known to mineral and gem collectors alike.
