Very aesthetic lustrous and translucent crystals of this rare lithium-rich red mica, ephesite. This specimen, from the famous Postmasburg finds on a farm in the early 1980s, shows tabular micaceous shape, showing the classic hexagonal cross-section of mica. Translucent to transparent, excellent color. A good representative for the species.

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.
