Mineral Specimen #2011    Carrollite, Calcite, Chalcopyrite

Kamoya South II Mine, Kamoya, Kambove District, Katanga Copper Crescent, Katanga, Democratic Republic of Congo

Cu(Co,Ni)2S4

On this specimen, there is a single well formed Carrollite crystal which measures 16 x 14 x 11 mm (as measured on the flat side of the crystal). On one side of this crystal, there is a triangular flat face with a very high luster. On the three sides of this triangular face there are beveled, striated sides which also have a high luster and at the apex of this triangular face, there is another flat face with high luster. On the other side of the crystal, the surface is flat with growth lines. On this side, there are some voids in the crystal which are missing. These are either damage or due to how the crystal grew. It does seem likely that this side of the crystal was in contact with a now missing Calcite crystal. Overall, this main crystal is in good condition. It appears that most of the surfaces of the Calcite are cleavage planes. Most of the rest of the Carrollite and the minor Chalcopyrite are crudely formed crystals or are damaged.
