Is it true that if you set a real diamond (flat side down) on a mirror and tip the mirror sideways and it sticks to the mirror, does it really mean that it is real.....or how can you tell if a diamond is real???

Try the list here. It doesn't list the method you mentioned, and to be honest, I don't see how it could possibly work -- why should a diamond stick to a mirror?
Ultimately, the only way to know for sure is to have a professional do an appraisal.

I've never heard that about diamonds before. I've never had a loose one just laying around I could try that with either. But how jewelers judge whether diamonds are real is the same way they determine how any other gem is real, and how much it's worth: by the clarity, color, cut, quality, carat, ect. Not something a layperson could figure out by a simple test.

Rub the diamond against your teeth. If it feels rough, then the diamond is real.

And if it's smooth, does that mean the diamond is fake or that your teeth are?

Easy, just take it to my x-ray diffractometer and check out the pattern.
If you don't work in a materials lab, I think you could use the Archimedes route and at least figure out if it's diamond or cubic zirconia. Diamond has a specific gravity of 3.5 while CZ is way up at 5.6 to 6.0.
The easiest way is to just ask the dealer whether or not the gem is in fact a profoundly overpriced run-of-the-mill stone for which an entire village was macheted to death to ensure its artificial value through supply and price control. If the answer is no, be careful, it might be fake.

Slightly off topic, but on CSI Miami last night they identified a stolen diamond because a miniature serial number had been etched onto it using a laser. This was supposed to be standard practice for diamonds. Is this for real?

'Tis. You can have it done for an extra fee when you buy a diamond from the big box outlets (Zales, etc.). Dunno about it being standard practice, but it is available.

When I found a diamond ring in my yard while digging. I just took it with me the next time I went to the shopping mall and stopped by a jewler. They changed me nothing to check the diamonds this one of those electronic testers.
BTW, the large .5 ct center stone was real and the little stones around it were CZ.
