Louven jewelry that is plated in yellow gold or rhodium is a Brass base metal. We recommend you clean your plated jewelry with a soft cloth after each use. Plated jewelry shouldn't be worn in a swimming pool, while bathing, exercising or while putting on lotions, perfume or hair products. Do not use harsh chemicals, even jewelry cleaners or polishing cloths, as these can also affect the finish of your piece. We ask that you follow the care instructions to ensure the longevity of your Louven product plating. Our Rhodium plated jewelry is recommended for individuals with sensitive skin as rhodium is hypoallergenic. Contact us for requests on Rhodium plating on any of our collections.
