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" components are 18k gold-vermeil, and the parts move independently. The posts and backs are sterling silver.
