We have several design options for the metal ring. The copper patina makes each piece unique and beautiful. Cut from quality 14 gauge, recycled steel, you could hang the ornament on an outdoor garden hook, a back porch, an indoor wall, or attach it to a wreath. After we complete the patina process, we finish each piece with a clear coat to keep the coloring and minimize rusting. Each ornament measures 9.3" in diameter with a 1/2" hook at the top. You also have the option to have the piece left in raw steel or finished with a matte black.
