Descloizite

Unknown Owner
A crystallized calcite matrix, this hosting many lustrous sharp crystals of descloizite measuring to 0.5 cm in size. The calcite is fluorescent under longwave ultraviolet light. This is in terrific condition. A neat example from this classic locality.

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.
