Sharp pseudo-hexagonal crystals of pyrrhotite to 2.5 cm in size, these coated with lustrous crystallized galena and set nicely on matrix. This is in good condition.
Dalnegorsk, located in the Primorsky Krai of the Russian Far East, is a world-famous mining district with a history of industrial metal extraction dating back to the late 19th century under the entrepreneur Julius Brynner. Geologically, the area is dominated by complex skarn deposits formed through the intrusion of Cretaceous and Paleogene magmatic rocks into Triassic and Jurassic carbonate and sedimentary sequences, creating ideal conditions for large-scale hydrothermal mineralization. Mineralogically, the district is celebrated globally for its stunning, large-scale specimen production, most notably pristine crystals of calcite, quartz, sphalerite, galena, and a wide variety of borate and skarn minerals that remain staples of major museum collections worldwide.
