A beautiful and large manganoan calcite with minor manganese from the Kalahari Manganese Fields in South Africa. The specimen is a lovely pastel pink, with little black microcrystals of manganese on its surface. On the back side are spikes of tan kutnohorite. Good Wessels Mine specimens are now very hard to obtain! This pretty piece came out of the collection of Ed David.
