Calcite var Manganoan

I bought this specimen during my trip to SA/Namibia in 2006. It likely came out in the 1970’s, Similar in appearance to the Kutnohorites from this area, the mangano calcites fluoresce intensly while Kutnohorite does not. A lovely pink color with a chalky luster and complex form. If not for having another, similar one this would be a keeper.

Locality: Nchwaning 1 Mine, Kalahari Manganese Fields, Northern Cape Province, South Africa

Composition: calcium carbonate
