1) It had to "snug" (aka fit perfectly with my turn of the century engagement ring setting which I did not want to change).
2) It had to stand on its own as a design without the engagement ring for the rare occasion I wanted to wear just the wedding ring.
Too much to ask you say? Well he did it and I am thrilled with the results.

Note the fine etching on the leaf on the side view. I couldn't believe it, but he solved both issues beautifully. I can't WAIT to wear it for real come September :)
Mr. Onion designed his own ring and doesn't want to share because he doesn't want it to be a "fad!" He's so cute. I'll keep working on him. He wouldn't let me share it my knot bio either. Kill joy! Doesn't he know weddingbee readers are on "a need to know basis" and they NEED to know?!
Fun Fact:
My wedding ring is a size 2 3/4! I'm not kidding. The jeweler didn't have a size small enough for me to try on (he said they had children's sizing rings but he didn't have them).
