Rhodium plating is a process that coats a fine layer of rhodium over white gold, platinum, and silver rings to increase their durability and shine.
Rhodium plating is not permanent, and it will wear off in time. The wear time depends on how frequently the jewellery is worn and how it used. The thickness of the rhodium plating also determines how quickly it will wear off. For example, a pair of earrings may retain their plating for many years, but a wedding ring which is exposed to daily wear usually requires another plate in 1-2 years. If the initial plating was extremely thin, an additional plating on a wedding ring may be needed in a few months to one year. There are a few simple steps to help ensure that your rhodium plating lasts longer.
Constant rubbing of your hands will accelerate the process of wearing the plating down. If you have a career in a medical profession where you constantly have to wash your hands and rub them together, the plating will wear faster. If the rubbing of your hands is unavoidable, consider wearing your rings on a necklace around your neck. Some chemicals may also react to rhodium plating and is advisable to either take of you rings while working with it or wear gloves. Rings that are loose and constantly spinning and rubbing against each other will wear the plating down. If your rings are spinning a lot it might be time to have your finger measured by a jeweller and have the rings adjusted.
