Calcite (Kalahari Manganese Fields, South Africa)
N'Chwaning 2 Mine, Kalahari Manganese Fields, South Africa. 50mm x 20mm x 5mm.
A lovely and oddly shaped Calcite from N'Chwaning 2. These where also referd to as "Hydrocalcites" at a stage, how accurate that is we are not sure but they ar certainly very different to the run of the mill calcite from the mine with the white coating the semi translucent calcites.
