Shakudo – Definition
Shakudo is the Japanese term for a copper and gold alloy consisting of 2% to 7% gold and the remainder copper. This alloy can then be treated to achieve a blue-black color sometimes resembling lacquer. It was historically used to make and/or decorate Japanese swords. Contemporary jewelry makers have revived the use of shakudo for its unusual and beautiful coloring.
