A few months ago, I asked a jeweler the best way to clean my diamond rings. It turns out, that store bought dip, swirl and scrub cleaning solutions can be harsh on diamonds. In order to get those diamond rings to sparkle, he recommended filling a glass with warm- not hot- water and fragrance free, clear dish soap. Soak your ring for a few hours and let it air dry. I recommend doing this while you are sleeping. When you wake up, your ring will sparkle and shine!
