Sharp spears shaped crystal grouping of lustrous slightly translucent descloizite crystals. The backside mostly coated with white sparkling small rhombohedral calcite crystals. In very good condition, the specimen comes with several labels from the collection of Rock Currier. The Berg Aukas Mine near Grootfontein in the Otjozondjupa region of Namibia is situated within the mineralized Otavi Mountain Land, a geological district famous for carbonate-hosted hydrothermal deposits and ancient solution cavities. Historically operated as a major underground producer of lead, zinc, and vanadium, the mine achieved worldwide renown among mineral collectors for producing world-class descloizite specimens. These secondary lead-zinc vanadate minerals typically developed in oxidized ore zones, forming dark brown, black, or reddish crystal crusts, druzy coatings, and sharp blade-like aggregates lining cavities within the local dolomite matrix. Although commercial mining operations have ended, Berg Aukas remains a premier historic locality celebrated for its remarkable descloizite treasures.

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.
