Freibergite crystals littering the entire specimen, though it is hard to tell from the photos. They have the triangular outline. The crystals are to 3mm and smaller associated with large plates of Pyrhhotite covered by other sulfides including Sphalerite and Boulangerite (acicular matts). The Semseyite occurs as weird sheaves or plates (as some describe them). Overall a cool study specimen you'll love to look at under the scope and admire in your hand.
