A glassy and lustrous, 7 x 4 mm crystal of the very rare lead arsenate Schultenite sits prominently at one end of a magnificent bed of superbly crystallised, mid to deep emerald-green Zincolivenite (formerly named Cuproadamite). Tsumeb mine is the type locality for Schultenite. The Zincolivenite forms sharp pointed gemmy crystals to around 8 to 10 mm. Also occurring on top of the Zincolivenite is a small cluster of milky Quartz crystals and very minor, micro-granular, grey Leadhillite. The Schultenite is semi-transparent and although colourless, does give occasional internal flashes of iridescent light-blue. The underlying matrix is a dark grey fine-textured mixed ore. This specimen comes with a University of Delaware Mineralogical Museum label. On the back of the label someone has written “look for keyite” as this is commonly associated with this assemblage; however, no keyite can be seen.
