Calaverite is a gold telluride. Unlike krennerite or sylvanite, silver is not essential to the crystal structure of calaverite (Bindi et al., 2009). The mineral name refers to Calaveras County, California, wherein the type locality lies (Genth, 1868).
Calaverite here forms a foliated crystalline mass on matrix, 2.4 by 1.2 cm. Elsewhere on the specimen are incomplete calaverite crystals to 4 mm in a quartz crystal lined cavity, and a 6 mm frozen bleb of calaverite. In this specimen, calaverite has a pale yellow color. An American classic.
