Dark grey, bladed crystals to about 1mm intergrown with acicular Boulangerite, Tetrahedrite, and Chalcopyrite. There are numerous crystals of Chalcostibite, but all at angles I could not photograph well. Generally the Chalcopyrite occurs as divergent, free-standing groups and always with the other sulfides mentioned. Of course all of the white crystals are needle Quartz.
