This specimen has more than a dozen extremely dark blue crystals of azurite on a matrix which itself is a conglomerate of many minerals. The azurite is so dark that even the edges are opaque and essentially black, but there are many internal fractures which reflect the deep blue color of azurite, and a few places reflect bright blue colors when the sunlight hits them. Only two of the azurites have an exposed length greater than 1cm.
