Spherocobaltite is a very rare (and thankfully beautiful!) cobalt carbonate, NOT to be confused with cobaltian calcite or dolomite which do not have as much cobalt in them. This is one of two beautiful specimens I obtained, from a find of the 1980s, with glittering, sugary, intensely colored maroon crystals of Spherocobaltite perched on matrix of rhomdohedral calcite. The druse underneath the crystals is probably acrystalline Spherocobaltite adhering to the matrix. The color is just...JUICY, for lack of a better word. I love these specimens and buy every one I see turn up, which is not very many these days.
