Tsumeb, Otjikoto (Oshikoto) Region, Namibia
Thumbnail, 1.5 x 1.2 x 0.6 cm
As extremely rare as this mineral is, to find it in such fine crystals (exceeding 1.2 cm in size) AND aesthetically put together makes this virtually incomparable as a display thumbnail. Just look at how lustrous and sharp these crystals are, and how aesthetic the cluster is! This is a killer specimen for the species, no matter what size you are talking about. 1.5 x 1.2 x .6 cm
