Hübnerite – Adams Claim, Silverton, Colorado, USA
 A particularly aesthetic and well-preserved hübnerite specimen of a wonderful size from the USA. Specimens from the Adams Claim differ significantly from the more common hübnerites from Peru. The crystals are particularly flat and form a fan-like sculpture.
 The bronze-colored hübnerites contrast vividly with the white quartz matrix.
 Specimens of this quality and size are extremely rare and highly sought after by collectors.
