Just because they "glow" in black light doesn't mean they're fake. It's pretty common (20%?) and referred to as "flourescence". Have your friend think of it as an extra special feature of those three diamonds..

A diamond with fluorescence may look like this under black lighting.

If they were glowing blue that's an indication that they are in all likelihood NOT cubic zirconia and are almost certain to be real diamonds. I've read that one of the ways to tell a real diamond is to see if it fluoresces blue. Obviously many (or most, I guess 65+%) real diamonds will not fluoresce at all, but I've NEVER heard of a blue fluorescing CZ. Several of my diamonds fluoresce blue and I have one that fluoresces a yellowish color.
