Since every other thread is about this I may as well take the moment to say that if you're a man and you're looking for a "cool" wedding ring or "something not traditional", you're a fucking fag.
Get a gold ring. If you get rubber or plastic you're not 100% gay, you're 120% gay. So don't be thinking, "I'm a le workman! I need a ring that won't get dirty!" Your father's ring looks fine you fucking nerd.
