I love my engagement ring, but it is an 100+ year old heirloom piece and I'm having a really difficult time finding a band to go with it. At this point, I'm considering moving my engagement ring to my right hand and just going with a band on my left. Or just ditching a band altogether. Can I get some opinions? I've attached the best option I've found so far. My wedding is in just over a month so I need to make a decision! Thank you ladies!

Re: Help with band for unique engagement ring?
Below is mine, It's kind of hard to see (I tried to separate the band and e-ring to show it better.) We had a custom made simple white gold band that kind of form fits my e-ring. I was going to go with one that has some diamonds but I changed my mind and asked for a plain ring b/c I felt like it showed off the e-ring better. Mine has pretty subtle curves so yours would have to be a big more dramatic with the curves but I feel like it'd look really nice and if you want to add diamonds like the one in your picture it'd look really lovely too!
The only bad part was I had to give up my e-ring for a week or so while they fitted the band to it!
Her reason being, is that she wanted to give the ring to me, when I turned 21 (which was tradition with this ring, it just so happened it worked out as an e-ring for my mom).
So, I got her e-ring, but she still had her wedding band, and then she "didn't feel naked" lol. She ended up getting a birthstone right hand ring. I wear the ring on my right hand now, but have a totally seperate ering, so no issue when I pass the heirloom to the next generation when they are 21.
Just something to consider..
I actually LIKE the look of Erings with gaps. It also looks better when you wear the band on it's own - I find the curved ones look funny on their own.
Here are some examples of other moi et toi rings w/ straight bands.

If you're going custom and you want it to look symmetrical, you could get two bands made, opposites. One for the top, one for the bottom. It's also common in other cultures to either a) only wear the wedding band or b) switch the Ering to the other side. So those are options too.
