my wedding band is a simple roundish gold band. nothing more. my ring doesn't match with it (white gold vs. yellow gold) -- but who needs a matching ring anyway? people look at my wedding ring with my engagement ring on the same finger and say that it's really unique that i went with "silver" and gold. (my watch matches, however -- i have the mixed metals in it)
anyway, i got my ring from fortunoffs and got a discount because i was registered there, but i don't know if they sell bands online.
