Dark olive green Kolwezite atop vivid pink Cobaltoan Calcite (or possibly Cobaltoan Dolomite) creating a stunning mixture of colors and forms. The Kolwezite forms two angular masses (as opposed to the normal spherical masses) and are possibly pseudomorphs. Kolwezite is a Copper Cobalt Carbonate Hydroxide and this is the type locality for the species.
