Our copper cuff has been heat treated to create a vibrant multicoloured patina. Copper has been used to promote health in various ways since ancient times. The ancient Egyptians used it to purify water for drinking, and cultures around the world used it as a form of medicine for such afflictions as sore throat, eye infections, and skin conditions. It was also applied to wounds to prevent infection. In the modern era, copper was discovered to have anti-microbial properties which made it well suited for its ancient uses.
