Is copper jewelry waterproof?

No, copper jewelry isn't waterproof. Because exposure to water can damage the metal, dry it off as soon as possible if you get caught in the rain or your jewelry becomes wet in some other way. To keep your jewelry looking new, remove it before showering, bathing and swimming. You should also take it off before applying hair and skin care products and before engaging in any activities that could cause it to become bumped or scratched.
