It seems to me that there is a market opening for the brave young entrepreneur who is ready to redefine the gendered engagement ring for the gay community. But I'm a little puzzled about the idea of gay wedding rings. We bought ours yesterday, and though there was a big difference between men's and women's rings, I can't say that any of the rings in either gender screamed "gay" or "straight". The form factor for a circular band seems to have been pretty well settled, and I'm just not sure there's a lot of room there to express your sexual preference.
Save your eyes. Take breaks.
