That is such a pretty setting!

I do wonder if a cross between these two would work

I really like the second one a lot but sometimes I think I lean towards

sans the surprise diamond so that it would sit flush.

I do understand wanting the ring to sit flush.  Part of why I'm back to a halo thought for my eventual reset.

I agree that the SO3375 would be too chunky particularly for your wedding band.  I also love the SO3039, but like you I want flush fit.  I am sure something could be done to make your perfect ring if you can't buy Daussis w/o a center stone.

SO3373 is also fabulous if you could have it made to sit flush. 

Just curious do you have a profile shot of your current ring?  I am just curious about how that one looks from the side. 

Here it is...

I thought about it but I am not sure how it would look with my ring. I ordered a matching band for my ring (same company but different manufacturer) and while I liked the look in general ... it didn't work for me because the two rings were too different.

Here are some photos of that set...

Lyta, DBL can make whatever type of setting you like, including a Daussi-like setting.

I would have a new band made to fit against your ring, just as this band does.

I can see where the band is a different design with the square shank, and it's slightly wider than the shank on your ER.  However, from the front I really had to look twice to notice the difference, and I like it better than the eternity ring with your ER.

Another thing, the new band may not match your ER. David probably will not be able to match it as well as you would like.  Once again, different manufacturer and David uses well cut F VS melee.  Perhaps, you should have both rings remade at the same time for a true match.
