Where do I find a ring(s) like this?!

[Dreamer1116]

apparently it is a 1.7 round center, with 15 .20 for the setting. This ring is just gorgeous!

Lots of vendors can order a setting like that. WhiteFlash carries smaller versions so I would think they could get the larger ones. I would want their quality if diamonds in the setting. Here is a smaller one. You definitely have to have a sizing area at the bottom.
