Engagement rings that aren't boring?... go with the c ock ring.
It would help to know what city you are in. I went to a small, family owned diamond company here in Nashville and got a super unique, vintage style ring for my fiance and we haven't seen anything remotely like it on anyone else. Find a company like that and you're going to get unique rings, support a local business and not end up with some ring you'll see at every Zales or Kay Jewelers.
