A rare and exceptional combination from the Kalahari that was unknown to me personally: of Cinnabar on Manganite. The Cinnabars are sub-mm crystals of an attractive cherry-pink color, spread liberally on the lush velvety surface of the Manganite. Charlie said he had never seen this material but in one pocket, and had it analyzed at Harvard as he was not sure what it was at the time. Ex. Charlie Key Collection.
