Berg Aukas is world-renowned for its extraordinary Descloizite (zinc analogue of Mottramite) specimens, and this piece is no exception to that. This superb small cabinet specimen has excellent spear-point crystals of Descloizite with fabulous luster and sharp, beveled edges. The translucent to gemmy crystals have stepped faces, and the largest is about 1.4 cm. The back side, if you can call it the back it is so good, is populated with over a hundred sharp mm-size rhombs of sparkly brown calcite specks. It is, in my opinion, just a tremendous small cabinet-sized crystal specimen for a species which is usually dismissed as dull, earthy, and ugly out of hand. Well, not this piece - the aesthetics are truly great on this competition-level specimen.

Regional guide
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.
