Kolwezite after Cuprite on Cobaltian Calcite
available$550
Dark olive green crystals of Kolwezite that have pseudomorphed Cuprite crystals atop vivid pink Cobaltoan Calcite (or possibly Cobaltoan Dolomite) creating a stunning mixture of colors and forms. Both mineralogically interesting and aesthetic. Kolwezite is a Copper Cobalt Carbonate Hydroxide and this is the type locality for the species.
