Demesmaekerite With Uranophane (??)
Musonoi Mine, Kolwezi, Western area, Shaba Cu belt, Shaba (Katanga), Congo (Zaire)
Miniature, 4.3 x 3.9 x 2.9 cm
Superb, unusually large Demesmaekerite crystals with micro-crystalline yellow mineral in association. (6 mm crystal). At a guess, the micro-sized acicular yellow crystals are almost certainly Uranophane but this has not been analyzed to prove it and they may be somethign more rare
