Item Description

Plancheite is a rare secondary copper silicate. Striking and beautiful, powder-blue, matte-luster, plancheite botryoids with complimentary calcite crystals RICHLY cover the sculptural matrix on this very showy and excellent specimen from the famous and now-closed Tsumeb Mine. The color is powder-blue, and the piece displays several angles to shwo there is a LOT of it present. This is an exceptionally rich and large specimen for the species and renowned locale. You do not see much of it, that is for sure, from Tsumeb. Because the mineral now comes in modern times from Kaokoveld too, this could be said in cando to be valued $750-ish to normal people; but perhaps to $1500 for Tsumeb nuts who must have one to complete a suite. And in this size and quality, its aesthetic and worth those kind of numbers, I think. Ex Rob Smith Collection.
