Item Description

This is a very impressive, 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 superb, sharp, lustrous, aesthetic, jet-black crystals measuring up to 4.2 cm across forming a beautiful "flower"-like crystal group associated with a gem Quartz crystal and minor Arsenopyrite crystals. The piece is great shape overall especially compared to the vast majority of specimens which are badly damaged. 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 $950 retail.
