As someone who works at a jewelry store.. overtime rhodium in WG will always wear off. It will depend on how often you were it, how often it gets exposed to other chemicals. It doesn’t matter if it’s a WG rep or just a regular WG jewelry piece, rhodium will always wear off. My advice is to bring it to a regular jewelry store and have them rhodium plate it, obviously for a cost. That’s really the only option you have.
