Anyone know where I can get a silver bow ring like this...?

So nearly a year ago I mentioned my boyfriend I may want this ring for christmas. I told him I was going to go to the Built by Wendy shop as I had no idea what size ring I was. Anyway, I never had the chance to go to the shop so he ended up getting me an iPod touch and I forgot about the ring.

I was just recently reminded of it and would love to get one like it. builtbywendy.com no longer sells it :( Any ideas where I could get this ring or one like it?
