My FH proposed giving me a gorgous emerald cut halo ring. I love it! However, finding a wedding ring is proving to be difficult. I would like to find a band I could get sauter(?) together, so part of the band would need to sit flush against my engagement ring. A jeweler suggested I look into curved rings. I found a curved ring I LOVE, but the woman who makes it said it won't set flush to my engagement ring. She suggested a negative space ring. My only issue with the negative space ring is that it isn't a circle. Should i get the negative space ring or look for something else?
First picture is my ring.
Second picture is of the curved ring I LOVE.
Negative space picture will be in the comments.
