Nice specimen of Sturmanite crystals from the famous NChwaning Mines, South Africa. It comes from the collection of Sandro Maggia, Italy with label. It displays orange-brown colored crystals. The Sturmanite has good shape and luster. The black sparkling background gives good contrast. For references see the 2017 issue of The Mineralogical Record vol. 48, # 1. In good condition – some contacts.

Pleasing Sturmanite!
