Olmiite (Kalahari Manganese Fields, South Africa)
N'Chwaning 2 Mine, Kalahari Manganese Fields, South Africa. 50mm x 40mm x 30mm.
Had it not been for the small knick on the one side this specimen would have been a classic museum specimen. The Olmiites are surrounded by small clear calcites and this is one of the gemmy specimens. It will all depend on how one displayes this specimen but the price certainly makes up for it either way.
