Description

Very interesting specimen of the rare corvusite and rossite from this famous American mine. Possibly other rare vanadium and uranium minerals are also present, such as coffinite, pascoite, carnotite, fervanite, etc. some of these minerals are TL.
Note. These minerals are presented as impregnations in a matrix of sandstone and clay, so they are very disintegrable. I can pulverize the minerals and put them in silicone ampoules but I have preferred to offer them as they are, but I want to warn that, due to their nature, during transport they can suffer damages, if someone does not want to take the risk, please don't bid for this piece.
