I like your current set (option #3) the best. The slight separation of the ER and the WB allows for the eye to see 2 distinct rings (vs. melding into one big band) and I love that. The proportions of the 2 are the most pleasing to me and it is a classic set IMO.
Problem solved...it is the size of the diamond that was bothering me...so I went to Tiffany to try a with a biger center stone: 90 points...this is better !!!
