RM2984   Mangan-diaspore

Glosam Mine, Western Belt, Northern Cape, South Africa

Rare and good sized mangan-diaspore (diaspore with manganese) specimen showing brilliant, transparent to translucent, burgundy red tabular crystals disposed in an arc on matrix. We can also observe small geodes full of crystals. The Glosam Mine specimens are the only ones in the Kalahari area in which the manganese diaspore shows this intense color and brilliance. An exceptional specimen for a little-seen species.

Size: 10.2 x 8 x 6.2 cm.
Main crystal: 12 mm.
