Item Description

The Siete Suyos mine (Seven Servants mine) is sometimes considered to be part of the Animas mine, and it is often difficult to know where specimens are from because several mines in the area share the same vein system. The good news is that I directly obtained this specimen from the miner who collected it, so I know for certain where it came from. I honestly have never seen any specimens from this locality before, but I was happy to purchase the pieces I obtained. This piece features a few sharp, translucent, greenish-brown hexagonal crystals of Siderite measuring up to 7 mm which are sitting upon crystals of lustrous Pyrite (pseudomorphs after compressed rhombohedra of Siderite) which are associated with minor grey crystals of the rare sulfide, Stannite. So far, this find was very limited, so if you're a collector of Bolivian minerals, be sure to pick this one up.
