  • A large, impressive mineral specimen featuring a dense coverage of shiny, dark reddish-brown to black descloizite crystals in distinctive spearhead formations. The crystals, which show amber translucency, are arranged in a complex, overlapping pattern across the entire surface of the specimen. The piece is roughly triangular in shape when viewed from above, with the crystals forming dramatic, three-dimensional projections that create a textured, sculptural appearance.

This is a truly grand - and significant - statement piece of descloizite from the Berg Aukas Mine, long regarded as the undisputed best for the species! Berg Aukas was mined between 1913 and 1978, so even the most recently discovered pieces are almost half a century old. It's rare that one ever comes across a specimen this large from any locale. Not only does the size make it stand out, the whole face is covered with ‘spearheads’, the most desirable form of the mineral (most large pieces consist of much less attractive habits), and strong amber translucency also stands out in many of these blades. The combination of size, form, color, and visual impact make this one of the best pieces of Berg Aukas descloizite that I've seen anywhere. With the size of this piece, there's naturally some damage present, yet there are just so many quality crystals covering the face of it. This is a truly important and irreplaceable piece that speaks for itself!

 

 

More info:

Descloizite from the Berg Aukas deposit occurs within dolomite-hosted vanadium-lead mineralization zones, where it forms as a secondary mineral in oxidized portions of the ore body. The crystals display characteristic dipyramidal habits reaching 2 cm, exhibiting colors ranging from dark red-brown to orange-brown depending on minor element content. Well-formed crystals typically develop in vugs and along fracture surfaces, often associated with calcite and other secondary minerals. The mineral formed through oxidation of primary vanadinite and galena, where mobilized lead and vanadium combined under oxidizing conditions. Variation in crystal morphology and color intensity reflects local changes in fluid chemistry during precipitation, while systematic zonation patterns within individual crystals indicate fluctuating oxidation conditions during growth.
