description:
Quite good for the species, a loose metallic bright crystal of native bismuth. In good condition all around. The specimen comes with a previous label from the collection of Ray DeMark. He acquired the piece while in China and 1982.

The province of Jiangxi in southeastern China is renowned for its rich polymetallic ore deposits, formed primarily through intense Mesozoic magmatic activity and hydrothermal fluid circulation associated with granite intrusions. Hydrothermal veins cut through local sedimentary and metamorphic strata, depositing significant concentrations of tungsten, tin, bismuth, and associated minerals, most notably across the famous South Jiangxi tungsten district. Mining in the region has a long history, expanding dramatically during the twentieth century to establish Jiangxi as a global hub for non-ferrous metal production. For mineral collectors, Jiangxi is famous for producing exceptional native bismuth specimens, often occurring as distinct metallic tin-white to iridescent skeletal or hopper-like crystals embedded within quartz matrices or alongside wolframite and molybdenite.
