For a charming addition to any jewelry design try this rusted iron heart key pendant. Its sleek display is shaped like a large key with a heart-shaped top and finished with a leather brown color outlined in black. With a top stringing hole this pendant would be the ideal focal point for a necklace laced with turquoise components to create a fun Southwest feel. Each component is made by laying cold rolled iron strips on farmland and letting it naturally create a rust-like finish. Once this happens, the shapes are cut out and each piece is sealed with a water-based acrylic to prevent future rusting. Because of this natural process, no two pieces will look identical.
