Smithsonite With Copper (Rare Association)
Small Cabinet, 7.3 x 5.9 x 4.5 cm
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia
Ex. Charlie Key
Unusual in many respects, because native copper is rare at Tsumeb and when found, is usually not associated with the lead minerals there, this is a very interesting combination piece: In a vug lined with a thick sheet of native copper are emplaced well-formed rhombohedrons of lustrous and translucent, colorless to ivory-colored smithsonite, to 1.25 cm in length. The copper bubbles up in parts through the smithsonite coverage, and is composed of hackly masses that offset the luster and form of the smithsonite. An old specimen, from the noted collection of Tsumeb specialist Charlie Key. a rare copper specimen from a rich copper mine, that produced paradoxically few examples of specimen-quality native copper!
