Minerals / Sphalerite, Origin unknown.

Sphalerite   is ZnS, Zinc sulphide, a major ore of zinc. The specimens location is unknown, but included in my collection as a "type specimen" The crystals are small, only two mm on average. They are well formed tetrahedral crystals which on first inspection appear black in colour, however, when viewed under high magnification the crystals are an intensely deep red in colour. There are also minor amounts of calcite, and quartz scattered around the specimen.
