Ferberite

A classic “V”-shaped twin (twinned along the {100} face) of Ferberite from the famous Tasna mine in far southern Bolivia. This locality has produced what must be the finest twinned Ferberite crystals extant. Ferberite, as a species, is not known in well-crystallized examples worldwide, and the twins from Tasna are a favorite among collectors. This twin is a great example of the material as it shows a fairly “open” twin, with aesthetic form. Along with the amazingly sharp faces, good luster and minimal damage, it’s a very worthwhile representation of these classic specimens.
