The bulk of this specimen consists of a few intergrown Galena crystals. Like most Galena, these crystals are opaque, have a dark gray color and a metallic luster, and occur in the cubic form. They are all intergrown, and the two largest crystals are interpenetrating at a shallow angle to each other. Two well-formed but incomplete hexagonal prismatic calcite crystals span the distance between two perpendicular faces of the specimen, so that only their prisms are visible. A small amount of their dirty limestone matrix is visible, and contains small and misshapen Galena, calcite, and pyrite crystals. None of the Galena faces seem to be cleaved- I am pretty sure that this is the natural form of the crystals.
