Since most people will be obsessed with their diamond engagement rings, they tend to clean and polish it frequently in order to maintain its ultimate sparkle and appeal. However, this may sometimes have a negative impact on your diamond rings depending on the metal settings. If you own a gold diamond ring, for instance, you can clean it as frequently as you want; just make sure to use appropriate cleaning agents while at it. Having said that, polishing your diamond rings is totally different from cleaning it. You are removing a tiny layer of gold from your ring by means of buffing, in order to make it lustrous. So, if you polish your rings regularly, it may make your ring vulnerable to wear and tear over time. When it comes to white gold diamond rings, it will be coated with rhodium in order to offer a lustrous appeal. If you clean and polish it regularly, the rhodium coating will vanish over time, revealing an off-white metal with a yellowish tinge.
