three stone rings & flush wedding rings

Have you checked out Precision Set? They make rings to sit flush with wedding bands, including three-stone rings:


I think a three-stone e-ring can definitely sit flush with a wedding band so long as you plan for it when getting the e-ring made. But a lot won''t sit flush so you''ll have to be careful and picky, and make sure you factor the w-band into the e-ring decision.

I upgraded recently to a three stone simular to the one posted in the op.  I had a five stone anniversary ring (straight across) that I had to have remade to shadow my three stone in order for it to sit flush.  The jeweler used my stones from my anniversary ring and made a new gold band to go with my three stone. 

I looked for four months to find a band to sit flush, and I could not find one.  So, I then found a good jeweler to do the work for me.  I love it.  I still have not figured out how to post pictures though.  I have had other things going on.  Maybe I will try this weekend.  Good luck in your search!
