I create my copper finishes using a Japanese technique called "Hiirodo" where I heat the finished copper shape until brightly glowing, then plunge it into boiling water to achieve a plum red appearance. The "wave" component is oxidized sterling silver, the loop is 18k vermeil, and the posts are sterling silver. I finish these with 23k goldleaf and freshwater pearls.
