Ametrine (natural bi-color Quartz)Ametrine 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

There are only two places in the world where I've seen crystals of Apatite with these beautiful green "Byssolite" inclusions

the color is a dark purple hue

white to off-white color Hopeite crystals which vary in habit from slender “blades” to incredibly well-formed blocky orthorhombic crystals

a single pocket of what is considered to be the finest discovery of the species known took place in one of the most unlikely of localities
