Sengierite on Dolomite

Rich specimen of green Sengierite on Dolomite from the iconic Shinkolobwe mine in the DR Congo. Good for this very hard-to-get uranium and vanadium mineral. This is from a small set of specimens kept intact from the 1950’s and thought to have originally perhaps been property of the United States Atomic Energy Commission, who was closely involved with mining at Shinkolobwe in the WWII (and later) period due to the importance of Congolese uranium ore in the Manhattan Project as well as the development of nuclear energy. Ex. New Mexico Mineral Museum. Rare!!
