This is a very attractive display specimen of Ferberite from Bolivia. This species was sometimes previously referred to as "Wolframite", which was supposed to be an intermediary species between Ferberite and Hubnerite but has since been discredited. The piece features rather large, sharp, lustrous, aesthetic, jet-black, tabular crystals of Ferberite with thin gem quality prismatic Quartz crystals on matrix. The specimen is is great shape overall, and allows for multiple angles to display the piece. These Bolivian Ferberites are often underrated and stand up very well against any other Ferberites from China or Panasqueira. This piece is from a find in 2007 which produced some of the finest Bolivian Ferberites in recent memory.
