alder cone earrings

These beautiful earrings are made from real alder cones. The cones have been coated with copper using an electroplating process. The alder cone is therefore still inside the pendant.
 The ear hook is also made of copper.
 The copper was blackened with a patina, polished as a finish, and then sealed to protect against oxidation.
