Olmiite (Kalahari Manganese Fields, South Africa)
N'Chwaning 2 Mine, Kalahari Manganese Fields, South Africa. 30mm x 30mm x 10mm.
This Olmiite clearly formed in a thin wedge - it has what looks like a contact on the one side, the opposite still has the Manganese orbody attached to it. Note the colour is less saturated than shown, when photographing these the colour inexplicably deepens. Estimates shipping weight including packaging +/- 90gr.
