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 a brassy mass in matrix. Associated are greener chalcopyrite and also grayer coloradoite. Kalgoorlie is noted for its rich masses of calaverite, which may reach 40 cm across.
