Miargyrite - Sold

Miargyrite is a silver antimony sulfide. The mineral name comes from the Greek roots for less and silver, since the mineral is relatively poor in silver compared to traditional silver ores (acanthite, proustite and pyrargyrite). The mineral miargyrite was one of the first minerals to undergo crystal structure solution (Hoffman, 1938), which was later refined by Knowles (1964). Hecla operates the Rosebud mine, which occasionally yields fine specimens of miargyrite as seen here. This specimen shows bladed crystals to 5 mm on contrasting white quartz. Good but small piece.
