Smithsonite with cerussite, Tsumeb; 10" Across

This may be the best cobaltian smithsonite in existence. It was formerly in the renowned Tsumeb mineral collection of Marshall Sussman.  Smithsonite is zinc carbonate.  Cations of copper, cobalt, manganese, cadmium, calcium, lead and probably other divalent cations replace zinc cations.  Zinc cations are the only species present in the "uncontaminated" smithsonite crystal lattice but when some of these cations are substituted for by cobalt cations, the smithsonite is pink and described as cobaltian smithsonite.
