Description:This is an 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 several good, sharp, lustrous, aesthetic, jet-black, bladed crystals measuring up to 2.7 cm long with minor silvery-grey blades of Arsenopyrite on matrix. Overall, the specimen is in great shape, (only a littel bit of notable damage) especially compared to the vast majority of specimens which are badly broken. 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. Valued at $350 retail.
