I also just wear my wedding band -a plain platinum band + promise ring before we got engaged, a Tiffany Etoile diamond band platinum. It's very elegant and I like stacking bands together.
My beautiful e-ring's in the safe deposit in the bank. It seems I've taken on my mom's style of just doing bands. I admire her and her style VERY much so I do follow some of her leads.
I also saw a spread Jennifer Aniston did for a fashion magazine (when she was still happy with Brad) and she was wearing two bands stacked together and I thought that just looked SO cool! She could've been flaunting her crazy diamond, but just went for simplicity, which is totally my style!
However, 5 year anniversary coming up next year and dear hubby wants to buy me a 4-row Tiffany Etoile diamond band!!! I'm so excited because it's very beautiful! However, I will want our jeweler to design it because it'll probably cost a lot less than Tiffany's insane markup!
