An extremely sharp and well-terminated, 1.3 cm, metallic-gray "schwatzite" or mercurian tetrahedrite crystal aesthetically centered on quartz matrix from the Type Locality - Schwaz, Inn valley, Tyrol, Austria. This was briefly considered a separate species for some time. This is a very LARGE crystal for this RARE species and locality, which is not diminished by trivial termination edge wear. Ex. George Elling Collection.
