Owyheeite - Sold

Owyheeite is a complex silver lead antimony sulfosalt (Moëlo et al., 2008). Shannon (1920) originally described this mineral as silver-jamesonite, but in his review Wherry (1921) deemed the mineral sufficiently distinct to assign it a separate species name. The name owyheeite recognizes that the type locality within Owyhee County, Idaho.

Owyheeite here forms fibrous masses in a cavities in a quartz vein. Two larger pockets, both filled with lead gray fibers, each measure 8 by 5 mm across.
