Dark olive green botryoidal Kolwezite atop rhombs of vivid pink Cobaltoan Calcite (or possibly Cobaltoan Dolomite) creating a stunning mixture of colors and forms. The large central crystal group is partially etched and reveals alternating layers of varying intensities of pink coloration. Kolwezite is a Copper Cobalt Carbonate Hydroxide and this is the type locality for the species. A beautiful large display piece and combination specimen of two desireable species together.
