whatever you do, DON'T go to zales. I feel like this should go without saying but your post earlier terrifies me. jewelry stores in malls are absolutely NOT OK for buying engagement rings. Think about it, this is the single most amount of money you'll ever spend on a piece of jewelry most likely. go somewhere that actually sells a real product. Online: Meh. I'm not a huge online guy, I looked it up and I would have saved about $300-$400, not worth it IMO, I'd rather support a business here, but that's just me.
Good luck fanman!
