Choice, 1.8 cm cluster of bright, silvery Stephanite crystals from the historic mines at St. Andreasberg. The metallic luster is excellent, and the tabular crystal habit with classic notches is attractive and interesting. This is a very fine thumbnail, and it was just published in the Mineralogical Record's new special issue on St. Andreasberg as a nice bonus validation (MR May-June, 2017)!
