Cuprosklodowskite, Metatorbernite
Musonoi Mine, Kolwezi, Western area, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaire)
Small Cabinet, 6.5 x 4.5 x 4.0 cm
This gorgeous specimen features EXCEPTIONAL crystals of both species, but in particular the Cuprosklodowskite! The Cuprosklodowskite crystals reach almost 1 inch in length and have an amazing metallic green brilliance to them, which contrasts with the darker transparent green of the torbernites (which are so sharp you can see why sometimes they turn up labeled as "green wulfenite!"). This is from old finds of this material, and dates to the 1970s I am told, in contrast to recent finds (admittedly, in quantity), much of which just didn't quite have the brilliant iridescence combined with length of the best of these older crystals. I also cannot recall seeing as fine an association of the two species in the recent finds of CS from this locality, come to think of it, clearly confirming this as an older specimen. 6.5 x 4.5 x 4 cm
