This is a very attractive display specimen of Ferberite from Bolivia. The piece features several sharp, lustrous, aesthetic, jet-black, tabular crystals of Ferberite forming beautiful "flower"-like crystal group. There are only a few minor spots of damage on the specimen, and for the overall appeal and dramatic impact of the piece, the damage does not detract. These Bolivian Ferberites are often underrated and stand up very well against any other Ferberites from China or Panasqueira. Ex. Brian Kosnar.
