An unusually rich specimen of Carnotite crystals up to 1 mm on a bed of blue Chrysocolla. Carnotite is a rare mineral at Mashamba and the specimens where recovered in the mid 80's. As the Mashamba mine is flooded and most probably exhausted, no specimens will perhaps never reach the market again. Crystallized carnotite is rare from any locality, and the aesthetics of this piece are particularly nice. Superb under a scope, too!
