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 i n 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 excellent quality, sharp, gemmy, greenish brown modified rhombic/hexagonal crystals of Siderite which are associated with crystals of lustrous, metallic Pyrite (pseudomorphs after compressed rhombohedra of Siderite). For Siderite, the quality is impressive for Bolivia, as I rarely have seen such sharp and gemmy crystals from any Bolivian locality. So far, this find was very limited, so if you're a collector of Bolivian minerals, be sure to pick this one up. Specimen # BOL711B238 Show more
