White gold is yellow gold mixed with white alloys, so the natural color is yellowish. It is then rhodium plated to give it the shiny bright white finish. With wear and tear the rhodium will start to wear to show the natural color of the white gold. Here are some tips to make rhodium plating last as long as possible:   Avoid rubbing the rhodium plating on your ring. For example, constantly washing your hands can wear it off quicker.   Avoid exposing your jewelry to chemicals. Always take off your jewelry when dealing with chemicals or wear rubber gloves to protect your rings.   Take your jewelry off when swimming in heavily chlorinated pools as the chlorine can damage the plating.   Perfumes and cosmetics can also affect rhodium plating. Avoid contact with these and wipe away any residue if it does come into contact.
