Ferberite with Pyrite, Quartz, Muscovite, and Arsenopyrite: Very aerial and well-defined groups of Ferberite crystals of black color and metallic luster, accompanied by hyaline Quartz crystals, as well as small Pyrite crystals partially coating the Ferberite. To complete the association, Muscovite and Arsenopyrite crystals are present—a classic combination in specimens from Minas da Panasqueira.
The specimen, of exceptional quality both in the definition and perfection of the Ferberite crystals, as well as in the overall aesthetics, is numbered and comes from an old exchange in the Folch collection. It is accompanied by a typewritten card and a handwritten note, which will be provided together to the purchaser of the piece.
