by ccuheartnurse » Jan 3, 2019 I can't tell any difference between the 2.14 & 2.28 re: colour. I do like the 2.28 (if that's the one on the right) because it looked like it had more fire which is what I'm drawn to 1st. I like both styles of rings you are considering. I think 2.8mm is a bit wide personally. Remember, you will have a band which will add more mm width. If you are going the custom route, I'd stick with 2.2-2.4mm.
