This Jbeg ring is what made me think rose cut moissys could look good in an eternity. Check out the hand shots, it's gorgeous! BUT, I wonder what it looks like in person? Would the fact that you can see your finger through the stones b ug me in person....I'm not sure. Maybe?
I love OECs and I love rose cut...I think a rose cut band would be great against an OEC/OMC engagement ring...but I would stick with all of the same cuts in the band. Unless you went with a big/small alternating eternity band...big rose cuts spaced by smaller oecs or vice versa.
