This is a beautiful specimen of irridescent chalcocite - the pictures can't do it justice. The individual crystals can be identified because each of them displays a different irridescent color, according to their orientation. These colors include blues, violets, purples, and golds. There is one crystal that is pseudo-hexagonal, looking a little bit like a shallow tetrahedron (upside down), but with the points replaced with short faces.
