Siderite with Pyrite and Stannite

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 several excellent quality, sharp, gemmy, greenish-brown crystals of Siderite measuring up to 14 mm which are aesthetically "stacked" on top of one another, and are associated with lustrous bladed Pyrite (pseudomorphs after Siderite) and minor grey crystals of the rare sulfide, Stannite. For Siderite, the quality is impressive for Bolivia, as I rarely have seen such sharp and gemmy crystals from any Bolivian locality. The back side of the specimen is not complete, but looks beautiful from the display side. So far, this find was very limited, so if you're a collector of Bolivian minerals, be sure to pick this one up.
