Perfect and sharp Ferberite crystals from the famous Panasqueira mine. Displays tabular crystals with black color and good luster. They are very well shaped with oblique tips and are twinned. Ferberite is partially covered by Muscovite on the front side and white Calcite on the back. That gives super contrast. Some metallic yellow Arsenopyrite is seen too. For references see the 2014 issue of The Mineralogical Record vol. 45, # 1. In excellent condition – some small nicks and base contacts. On acrylic base.

Superb Ferberite!
