Formulated especially for silver and turquoise jewelry. Will not scratch soft stones such as turquoise. Time-saving to use, since stones do not have to be removed before buffing a new piece. Leaves a high luster without residue. Fast clean up, does not cling to or penetrate surface of stones. Versatile, many goldsmiths prefer ZAM to rouge as a final finish. Available in 1/4 lb. or 1 lb. tube. Choose option.
