An extremely rare and showy Tsumeb pseudomorph of sparkly, greenish-gray dolomite over plancheite pseudomorphing a sharp, 2.9 cm, flattened azurite crystal. The crystal is nicely placed on plancheite-covered matrix. The bit of periphery damage is certainly not a detraction. An OLD specimen, very seldom on the market in this quality. Ex. George Elling Collection.
