Superb thumbnail of thick, elongated scalenedrons of very light Cobaltian Smithsonite. Such well-developed crystals, in this size (up to an amazing 2 cm) and thickness (4 mm) are quite unusual. These Smithsonites are lustrous, gemmy, and the cluster is quite aesthetic. Rarely will you find one this good. Ex. Georg Gebhard.
