Calcite on Hausmanite, (kalahari Manganese Fields, South Africa)
N'Chwaning 2 Mine, Kalahari Manganese Fields, South Africa. 45mm x 25mm x 10mm.
We have not seen a stricking combination like this in a long time. The shining jet black Hausmanites being offset by these wonderful white calcites. This is a very pretty specimen indeed, it is also a real challenge to photograph!!
