A coworker and I were discussing engagement rings (we work in the jewelery biz), and she made an interesting statement. She said she'd rather receive a 3 carat flawless looking cz than a .25 carat authentic diamond. I'd prefer a real diamond. Even if no one knew but me, it'd bother me to have a cz. If the guy can't afford a large diamond at the outset, there's always the opportunity to upgrade later. Just wondering everyone's opinion as it relates to engagement rings. I personally don't like cz ever.
