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.
Lithiophorite

Olesna, Horovice, Beroun District
Central Bohemia Region,
Czech Republic
7.1 x 6 x 4.4 CM (cabinet)
price: $40
A black ugly, nearly pure, globular Lithiophorite that is a very good example of the specie and the locality. From an old Czech collection, this Manganese Oxide mineral (with Aluminum and Lithium) is never a "pretty" mineral, but it is uncommon and this a rich specimen.
A fine and sizable classic silver psudo in outstanding condition. Very esthetic, a dense cluster of wires and branches cover the top side of the matrix which has been artfully etched from the enclosing calcite. Presents perfectly, this is an older piece from one of the greatest silver localities in Europe.
