This is a very sculptural Descloizite specimen, a killer miniature dominated by divergent sprays of relatively large Descloizite crystals from the classic Berg Aukas Mine in Namibia, the best locality in the world for the species! The piece consists of numerous, elongated, bronze-red, lustrous, fan-like aggregates of Descloizite to nearly 2 cm in size. These super-sharp, super lustrous, spearpoint-shaped crystals are well terminated and have no damage, and are of exceptional quality. There are at least two dozen showy crystals that make up this cluster. Most Descloizite pieces we see are dark colored maybe with a hint of red and perhaps a moderate luster, but this one is richly colored and bright; its form is both exquisite and artistic! It is one of the finest miniatures of this material we have seen, and dates to the 1960s. This comes with an old label noting "tsumeb" as was common in those days, when minerals from Grootfontein were sold by dealers in Tsumeb to foreigners, and mislabelled.

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.
