N'Chwaning II Mine, N'Chwaning Mines, Kuruman, Kalahari manganese field, Northern Cape Province, South Africa
A stunning olmiite with bultfonteinite from the N’chwaning II Mine, near Kuruman, in South Africa’s Northern Cape Province! The olmiite has brownish color that is contrasted beautifully by the snow-white bultfonteinite. The arrangement of the crystals is quite aesthetic and the crystallography of the olmiite is very intriguing. Ex. Jacques van den Berg Collection.
