Stephanite

Aesthetic 3.5 mm long and 1 mm wide crystal of stefanite with metallic luster dominates this Příbram specimen. In addition to stefanite, we see small dark crystals of sphalerite covering pyrite and sparkling tiny crystals of quartz. Apart from the dominant cluster of stefanite crystals, there are more shiny stefanite crystals in the cavity, about 1 mm in size.
