Here's an old-time specimen of simple selenite Gypsum. I showed this to G. Gebhard a few years ago and he agreed with the previous Prosper Willaims tag (prov tab) that it is indeed Tsumeb. It is a very nice, water clear crystal 3.5cm long with good luster and pretty much damage and scratch free. The matrix is probably tennantite.

Collected by Robert J. Waidler as a geologist at the mine, this is one of the finest selenite clusters found at Morenci. The crystals are long, slender to over 1cm and are waterclear. There are two very nice divergent sprays. The specimen presents very well and very little if any damage.
