Are you talking about a 22k gold plated chain? In this case, you need to consider what base metal is used. Copper and brass will be prone to discoloring, whether it's wet or not. Cheaper chains may use steel as a base metal which will be a problem in water. A simple magnet will tell you if it's made of steel.
Solid 22k gold is fine. It’s used everywhere for jewelry in India. My mom wears her chains every day and they hold up well. 24k needs to be handled carefully.
