This is an incomplete cluster/crystal of chacocite. I suspect that the original specimen was fractured into two roughly equal parts, and this piece is essentially complete and undamaged except for the smooth, conchoidal fracture that terminates one side of the specimen. The original surfaces have the typicalmetallic luster and suface pattern due to thousands of crystal faces, all deeply striated, that provide the appealing texture of good chalcocite crystals. The fracture surface, however, is relatively smooth (but not perfectly so). All of the surfaces are irridescent in various hues. One side of the crystal is primarily blues/yellows/greens, while the opposite side primarily displays reds, violets, and purples. The fracture surface shows all colors, including brassy hues. There is a small area with a thin white coating that looks like calcite.
