Ex. Henri Vandormael Collection

Excellent specimen of well-formed rutherfordine crystals on crystallized uranophane with sparse green cuprosklodowskite tufts from the famous Musonoi mine, Kolwezi, DR Congo. This is a great specimen for this rare uranium species, from the noted collection of Henri Vandormael, former mine geologist at the Musonoi mine and other Congolese mines for the Union Miniere Haut Katanga (UMHK) company in the 1960’s, 70’s and 80’s. This was later in the collection of noted uranium mineral specialist Eric Quinter. Very good for this species (rutherfordine) at the Musonoi mine! Measures ~125,000 CPM on my Ludlum Model 3 Counter with the 44-9 probe. Good crystallized uranium minerals from Musonoi are very hard to come by these days and this is a great specimen with a superb provenance. Rare!
