This buckle is made with three types of metals, nickel, copper and bronze. The buckle measures 2-1/2″x 3-1/2″, with a 1-1/2″ buckle loop on the back. The base of the buckle is 18ga. nickel with copper overlay border. the horseshoe is bronze with copper details. I put a nice oxidized patina to give it that rustic appearance.
