One of the most colorful and attractive of the Uranium minerals, the Copper rich version of Sklowdowskite. This one has the brilliant green needle crystals protected in a vug. The associated species are best seen with magnification but do add some contrast and color. From the famed mine of Musonoi in the Katanga Copper region that produced what are certainly the best examples of the specie more than 20 years ago, this is a good example that will not break the bank.
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.
