I think it depends.. if you like things more "structured", I would go with A - it has clean lines and I think the two horizontal bands really compliment the sharp edges of the center stone.
If you are more "go with the flow", I would absolutely pick C - as someone else mentioned, it is "unexpected", but I think it complements the e-ring! The band reminds me of clouds in the sky, while your center stone serves as the diamond in the sky
Thank you so much everyone! I made the right choice then. I really love C, probably because it is unexpected as you said. I bought A at first, but didn't really like the look of it, so I took them back. B I just tried on at the store, and C I actually took the ones from A back and bought C. It took me so long to finally find the one that I loved and I just wanted to make sure that I was making the right decision . To LouMom, It is .25ct swirl band with 22 diamonds. I got it from Shane Co. only because I just got a new ring custom made for my solitaire (because I wanted Kite set with tulip head) I kept my same diamond, but used the old unmounted ring from Shane Co as a trade in on this swirl band. Here is another view of it.
