Diamond Ad Disclaimer

Apparently, 'tis also the season to advertise diamonds like crazy, based upon the number of diamond ads I've been seeing on TV lately. The big slogan for diamonds used to be: "A Diamond Is Forever!" I haven't seen that one as much recently, but it was a good one. Unless it made people think it was forever because that's how long they'd have to be paying for it. (Diamonds are ridiculously overpriced.) But I think the reason they're not using it as much anymore is that most marriages end in divorce these days. So perhaps they should bring the slogan back, but with a disclaimer: "A Diamond Is Forever, Even if Your Marriage Isn't!" Or else they could just say the slogan: "A Diamond Is Forever!", and then have that announcer guy with the super-fast line readings say the following disclaimer extremely rapidly at the very end of the spot: "Just because a diamond is forever, it doesn't mean your marriage will be."
