Item Description
A seldom seen Calcite from the Osceola mine near Silverton. This specimen is filled with sharp, Calcite scalenohedra which have a dark chocolate brown coating of an unknown manganese oxide. The crystals have a matte luster and are clearly coated as the underside of the piece shows white/colorless Calcite crystals. A very attractive Calcite specimen to add to a Colorado collection.
