Arsentsumebite

Unknown Owner

This thumbnail specimen is an extremely richly crystallized Arsentsumebite from the Type Locality at Tsumeb mine, Namibia. Under magnification the vibrant green coatings of Arsentsumebite are seen to be composed of a myriad of bladed microcrystals and these extend into the specimen as intergrowths and within other smaller cavities. Ex Dr Hans-Jurgen Wilke collection who acquired it in October 1976, and ex Dr Eduard Lopatka coll.
