I've seen a few postings about wedding bands that work with a single solitaire in a four prong Tiffany setting. I'm leaning towards some of the diamond eternity but don't know if that's too much. Also, is it true that a white gold ring has to get "dipped" every year or so? I've only had mine for about 3 months and it's already not as "white" as it was when I got it. What does everyone do??
