Elegant ball of gemmy Olmiite set atop matrix!
The ball is complete all the way around, although the back side is somewhat flattened from matrix influence. Olmiite is named for Filippo Olmi, mineralogist at Centre di Studio per la Minerogenesi ela Geochimica Applicata, Florence, Italy. This sample is from the N’Chwaning II Mine, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa.
