Digenite with enargite and quartz. The digenite is the dark, crudely crystallized mineral with a steel blue tinge. The crystal at the lower right of the closeup is quite sharp for the species. Additionally, the "blob" in the center shows wonderful growth patterns on its underside. The enargite shows its typical prismatic, striated forms in the many gray lustrous crystals. Some scattered, corroded chalcopyrite is also present.
Origin: Leonard Mine, Butte, Silver Bow County, Montana, U.S.A.
