This sterling silver ring mounting holds one 10 x 8mm oval cabochon or other flat-back stone. The shank is decorated with etched diamond patterns that are oxidized for enhanced contrast. Use traditional bezel-setting techniques to secure the cabochon in the mounting. Place your stone in the bezel and push the walls inward over the stone, holding it in place. For added security, if desired, place a drop or two of jeweler's epoxy in the cup before placing the stone.
