This is a super aesthetic and very impressive, display specimen of Ferberite from Bolivia. The piece features several sharp, lustrous, aesthetic, jet-black crystals measuring up to 3,5 cm forming a beautiful display piece. The crystals are sitting on glistening metallic Arsenopyrite matrix with some small gem Quartz crystals. These Bolivian Ferberites are often underrated and stand up well against any other Ferberites from China or Panasqueira. And this specimen is suitable for highest aesthetic demands. The specimen was from the famous find in 1999 at Tasna. Ex Dietrich Meier collection.
