Calaverite - Sold

Calaverite is a gold telluride. The mineral name refers to Calaveras County, California, wherein the type locality lies (Genth, 1868). Unlike krennerite or sylvanite, silver is not essential to the crystal structure of calaverite (Bindi et al., 2009).

Calaverite here forms foliated and striated crystals on matrix. The largest crystals reach 5 mm long. Large crystals for the species. An American classic.
