Berg Aukas, Namibia has produced the world's finest descloizite specimens and this is an excellent and aesthetic specimen. Highly lustrous, two-toned, brown, spear-point-shaped crystals comprise this fine specimen. The deep chocolate-brown crystals have a complimentary, preferential, secondary overgrowth of tan calcite or dolomite. The largest spear-point is 2.3 cm. This fine piece is a very highly representative example of the species and locality, which closed in 1978. Ex. Jaime Bird Collection, obtained in January 1974.

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.
