Cabochons are cut and polished from natural green nephrite jade, used for centuries for its green color, true-grit hardness and classic beauty. Cabochons can include green shades ranging from medium to dark with black inclusions. Major deposits are found in British Columbia, Canada. Grades vary dependent on availability of rough material.
