A fine, 3-dimensional Tsumeb specimen with several vugs on 3 sides richly lined with scintillating, gemmy, emerald-green dioptase crystals. Several of the vugs are lined with sparkly pink, cobaltoan dolomite microcrystals, adding a very nice contrast to the dioptase crystals. Ex. Rob Smith Collection.
