This was one of the very few multi-twinned pieces from the find of these amazing specimens in June of 2010. 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. This beautiful piece features a few sharp, highly lustrous, jet black blades of Ferberite which are twinned along the a {100} face. It is not a simple twin consisting of two blades, but rather a few blades in parallel growth twinned together. The piece has a small contact towards one of the corners but, overall, is in great shape and displays well from a few angles. The luster is better than most of the Ferberites from this mine, and the piece is complete on both the top and bottom, and is not cleaved, which is impressive as most of the Ferberite twins are broken on one end. Bolivian Ferberites (especially those from Tasna) are often and sadly underrated/overlooked, but in many instances will surpass other Ferberites from Yaogangxian or Panasqueira for size and quality. BETTER in person, and difficult to photograph, as is the case with the majority of Ferberites from Tasna, they don’t like the camera, and take my word for it, this is good for the size and the fact that it’s a multi-twinned specimen. Specimen # BOL711B69
