A GORGEOUS, RICHLY-COVERED matrix festooned with gemmy and lustrous, cadmium-rich, yellow smithsonite crystals to 8 mm from Tsumeb. Cadmium smithsonite is the rarest of the smithsonite varietals from Tsumeb and finding a piece of this quality and coverage is very difficult. Very nearly damage-free from the Rob Smith Collection. 9.7 x 6.0 x 3.3 cm
