The Musonoi Mine produces the worlds supply of the finest cuprosklodowskite specimens. Sklodowskite and uranophane are two closely related minerals that have similar chemistry, structure and crystal habits. Cuprosklodowskite's bright green velvety tufts of hair-like crystals are very attractive and make an impressive mineral specimen. With its rarity and beauty, cuprosklodowskite is much sought after by rare mineral collectors. Remember, this is a radioactive mineral and should be stored away from other minerals that are affected by radioactivity and human exposure should be limited.
