Batman engagement ring made out of white gold and coated with black enamel. It features a 6mm ruby and mini Batman logos around the band. Despite the overuse of the term “black gold”, the true black gold doesn’t exist. There is no alloy composed of gold that makes it black all over. The color is achieved through black rhodium plating or enameling. This ring has a strong enamel that is more resistant than a thin rhodium plating. As with all coated items, scratching is possible, but this particular coating is easy to maintain by the client. Instructions are sent with the item.
