Tazna Mine (Tasna Mine; Tazna-Rosario Mine), Cerro Tazna, Atocha-Quechisla District, Nor Chichas Province, Potosi Department, Bolivia
Cabinet, 12.0 x 8.8 x 6.7 cm
This is a very impressive, display specimen of Ferberite from Bolivia. The piece features several sharp, lustrous, aesthetic, jet-black crystals measuring up to 4.0 cm forming a beautiful display specimen. The crystals are sitting on bladed grey Arsenopyrite matrix with a few small gem Quartz crystals. These Bolivian Ferberites are often underrated and stand up well against any other Ferberites from China or Panasqueira. This piece was from the famous find in 1999 at Tasna.
