Although the luster is not quite as bright and the crystals are slightly darker gray, this is my favorite bournonite specimen of this lot. Two, equant crystals, to 2 cm form a divergent "V" pattern. I particularly like the crystallography of these crystals. They are short prismatic, bi-pyramidal with large basal pinacoids. SO FEW clusters come from here!
