My wife wanted a diamond ever since we got hitched (we were far too poor at the time to even consider it). So now, years later, I told her "let's get you that ring you wanted". We went around for a year or so, to local loose diamond sellers, and then she saw "Blood Diamond" and that put a stop to that.
$60 later she's happy as a peach with a CZ ring she enjoys wearing. And on balance she says that she's even happier with it because she doesn't have to worry about it at all. If she loses it, it's not like losing a used car.
