Cuprosklodowskite is a rare, vibrant green, radioactive mineral composed primarily of copper and uranium. It forms as a secondary mineral in the oxidation zones of uranium deposits, often associated with other uranium minerals like uraninite and autunite.

Cuprosklodowskite is primarily a collector’s mineral due to its striking green color and rarity. It has no significant industrial use because of its fragility and radioactivity. Collectors prize well-formed crystals, especially those with vibrant color and good transparency.
