Berryite crystals from the Clara Mine, Black Forest, Germany – miniature specimen as unique piece
This miniature specimen features Berryite on a light-colored quartz and barite matrix from the famous Clara Mine in Germany's Black Forest region. The pale, partly translucent crystal aggregates are accompanied by numerous small ore minerals, creating an attractive and varied texture. Berryite is clearly present on the specimen, although the crystals are mostly small and closely intergrown with the matrix. The specimen is especially appealing because of its classic locality and the interesting association of typical Clara Mine minerals.
Geology & Origin
Berryite is a rare lead bismuth sulfosalt that forms in hydrothermal ore veins and commonly occurs together with other lead, silver, copper and bismuth minerals. The Clara Mine in the Black Forest is one of Germany's most important mineral localities and is internationally renowned for its extraordinary mineral diversity. Over centuries, hydrothermal processes produced numerous rare mineral species at this locality. Because of its scientific significance and remarkable variety of minerals, specimens from the Clara Mine are highly regarded by collectors around the world.
