Goethite Ps Pyrite with Calcite (Kalahari Manganese Fields)
N'Chwaning 2 Mine, Kalahari Manganese Fields, South Africa. 60mm x 35mm x 30mm.
These specific specimens where discovered in 2000 at the N'Chwaning 2 Mine. They have the typical curvilinear faces typical to the pyrite from the mine and of course the associated bright yellow Calcite is important. (The 2000 find was the only one associated with the bright yellow calcite hence the importance of this)
