Native silver is VERY RARE in Tsumeb despite its ore percentages, and specimens even more so. This is a relatively pretty example with contrasting silver on green matrix. Clusters of lustrous, iridescent silver combine with a druse of prismatic, light emerald green cuproadamite and blocky, forest green crystals of olivenite, to 5 mm across. This is an uncommon and rather interesting combo specimen. Ex Chris Amo collection
