Hopi use an overlay process, using a solid backing and a cut-out design, to create their unique jewelry. Most of the designs are Native American symbols or spiritual animals cut-out of the sterling silver top piece, joined with the solid back of sterling silver, usually the design area is oxidized to make them more visible. They make their special Native American designs into pendants, belt buckles, necklaces, money clips, bolo ties, rings, and earrings.
