Seligmannite, Sphalerite, Tetrahedrite

This is an interesting specimen. The largest crystals are twinned sphalerite that have a very thin veneer of chalcopyrite that gives them a golden look. There small clusters of seligmannite crystals on the sphalerite and are on, what I think, were once small galena crystals. There are also some sharp tetrahedrite crystals on the piece. Very interesting!
