I'm about to get engaged and I don't want a diamond. As Posh says, that doesn't show how much I'm loved or not.

Of course I want a big bling, but I don't see why I'd have to pay 20k to get it at tiffany u know? a Nice CZ bling should be ok, as diamond are NOT forever and PLUS, those get dirty too (from what I've seen on the jewelry i own)
