Perhaps the most beautiful and richly colored U mineral, Cuprosklodowskite from the Musonoi mine is revered by collectors, a "must have" specie. This specimen is quite fine, well crystallized with a dense mass of brilliant green needles protruding from a shallow vug. Several other rare minerals are also present including bright yellow Kasolite in balls and slender crystals. Except for this find in the Congo some decades ago these rare minerals are usually far from esthetic. This specimen is from that older era and quite a bit above average. Now very uncommon on the market in such quality.
