A very well-crystallized classic specimen from the ancient mining district of Pribram. The silver-rich Tetrahedrites had been called Freibergite but this is now a discredited specie name but exists as a subgroup tin the Tetrahedrite family. This is a superb piece with well-defined crystals on sizable Siderite crystals. The cluster of Freibergite/Tetrahedrite crystals is 3.2 CM across and is overall in good condition though there are some bruises to mention. despite that this is still a killer for the locality and specie. Silver was chased in this zone going back for centuries, later lead and finally Uranium were sought. Silver species are quite prized and well-crystalized specimens are now rare from this famed mine.
