From : Clara mine, Wolfach, Black Forest, Germany
About ten years ago there was a find in Clara mine of heavy massive Fahlore rocks (=Tennantite), with a grey metallic lustre. There is only a little content of Quartz, Fluorite, Barite and Chalcopyrite and so it is worth to cut and polish this massive Fahlore. This is a polished slab from this find, the backside is left in natural condition.
