Loose lustrous crystal grouping of descloizite. In good condition. Classic locality for the species.Berg Aukas, located near Grootfontein in the Otjozondjupa Region of Namibia, is a historic base metal mining district with operations that officially began in the early 20th century, around 1913, and continued through various phases until its eventual closure in the late 20th century. Geologically, the deposit is hosted within complex Neoproterozoic carbonate sequences of the Otavi Group, where extensive hydrothermal activity and supergene oxidation formed rich orebodies containing lead, zinc, and vanadium mineralization. Historically, the mine gained worldwide renown among mineralogists and collectors for producing some of the finest and most diverse secondary mineral specimens ever discovered, most notably world-class crystals of descloizite, vanadinite, and smithsonite.

Descloizite from Berg Aukas Mine, Namibia
Berg Aukas descloizite is one of the great “species-defining” classics: the locality by which serious collectors judge descloizite. The best pieces have a sculptural, almost architectural presence—dark brown to nearly black spear-point crystals, glossy blades, jackstraw bundles, radiating rosettes, and sharply terminated clusters that can look metallic under a show lamp yet glow warm reddish brown along thinner edges. Many specimens sit in pleasing contrast on pale calcite, dolomite, smithsonite, or willemite-bearing matrix, giving the dark vanadate crystals the visual authority of black lacquer against limestone.
