Manganoan Calcite (fl) on Tennantite and Sphalerite, with Pyrite
Atacocha mine, Cerro de Pasco, Pasco department, Peru
Cabinet, 13.9 x 11.5 x 5.0 cm
Ex. Dr. Art Soregaroli

From the mines of Peru we have a very good, representative combination piece. The matrix is predominantly intergrown, crystalline Tennantite, and it is draped with Sphalerites and decorative Manganoan Calcites. The Calcites themselves are adorned with hundreds of lustrous Pyrite pyritohedrons. The light pink Calcite crystals are about 2 mm in size and they number in the thousands as they cover half the specimen in ridges and mounds. Of course, the Manganoan Calcite has a rich orange-pink fluorescence. This cabinet specimen is in excellent condition, and the balance and aesthetics are very good.
