Soft, sectile mass of Acanthite with many crude forms of cubic crystals. The cluster at the tip is 7mm across. The specimen comes from the historic cobalt/silver Keeley-Frontier mine located in one of the largest silver mining districts in the world. The mine produced an incredible 3.3 million pounds of cobalt and 19.1 million ounce of silver. There is associated Calcite in mass and as crystals, a clear indication that the specimen was never etched.

This is a cut and microprobed specimen from the stock of Dr. Jaroslv Hyrsl. The Berryite can be seen as the black, slender blades. The Pavonite crystals are also the blakes blades so they cannot be distinguished visually. Aikinite is also present which further complicates the issue. Both Berryite and Pavonite are rare silver-bismuth sulfides.

Freibergite is the Ag-dominant analogue of Tetrahedrite. This is a very large and heavy specimen and may require additional postage. One side of the specimen is sawed and polished. The Freibergite can be seen on the polished end as nearly engulfing the entire host rock. Freibergite typically contains anywhere from 22 to 46% Copper and up to 17% Silver.
There are some fantastic crystals to 0.75mm in one area.
