This is a fantastic specimen of Cuprosklodowskite with Vandenbrandeite from the Type Locality for BOTH species. The very good Cuprosklodowskite crystals are very large for the locality. The Vandenbrandeite builds sheaves to 8 mm, what is also huge for the locality. Vaes discovered these minerals in the early 1930s in this remote area of Katanga. Kalongwe is located 60 km south of Kolwezi and was not very well accessible in that time because it lies in full jungle. This is why the deposit has never been mined, and will probably never be, so very few specimens reached the collectors. Outstanding and rich locality piece. Take advantage of this offer because nothing is coming out of Katanga anymore since more than 15 years, except for Malachite and Chrysocolla. And almsot nobody can provide a valid Kalongwe piece except those who dealt with the original exploration geologists and their collections.
