Yeah, I can't wear my ring either. It's too big. As such, I put it on my old dogtag chain and wear it around my neck.
My wife's engagment ring looks nothing like an engagement ring at all. So much so that people turned their noses up at it since it was not a diamond and didn't cost me an arm and a leg. That said, it is the one she wanted and I appreciate a woman who doesn't require me to prove my love in dollar amounts. She wears it on her right hand and her wedding ring on the left as they would not go together on one finger. Sooooo...yeah, get the one you love. If you are anything like me you will lose it 3 times anyway (well, hopefully not, but I learned after a while to go cheap since I would lose it anyway).
