A large cluster of dark brown ferberite crystals from one of the primo localities. The front of the specimen shows a large partial crystal of ferberite with slightly diverging, sub-parallel crystals. It has another partial ferberite crystal attached to the back of it. On the back, the ferberite crystals are partially coated by small siderite crystals. The large crystal is partial because the edge that it is resting on, in the photo, is a cleavage plane -part of the crystal is missing. Still a very impressive piece. R
