Look at it under a magnifying glass. Diamonds have carbon specks and inclusions (minor fractures) No black dots no diamond. a cz will scratch glass. Also if your real diamond has an inclusion (flaw) near where you scratch the glass you may in fact damage the diamond. Also you could damage the mounting.

The only people who can authenticate a real diamond are certified gemologists specializing in jewelry. However, if you are browsing rings at a flea market and want to quickly assess whether a clear stone is probably glass, cubic zirconium, quartz, or leaded crystal, there are a few easy tests you can apply without any special equipment. These tests at least rule out recognizable imposters because they rely on the way a real diamond stone refracts light, conducts heat, and looks up-close.
If the gem in question is loose and unmounted, try placing it over printing. Diamonds refract so much light that they will not work as a magnifying glass and you would see no lines, circles, or letters through them. Other clear stones like glass or crystal will reveal the print clearly. A similar test uses a small light, such as the one that comes with your key ring. If you shine the light through the stone and cannot see it on the other side, but only a bright halo around the rim, it is more likely to be a true diamond.
Diamonds are also very good at conducting heat. Breathe on the surface of the stone and immediately check to see if it has fogged up. Again, quartz, glass, and cubic zirconium will stay hazy for a moment before the condensation dissipates, but you shouldn't be able to see any moisture on a true diamond. However, one rock, called moissanite, will also pass this test, so the best way is to get a complete thermal conductivity evaluation performed by a jeweler.
Looking closely at the specks, ridges, and facets can also give you a clue into the identity of your gem. Diamonds do have inclusions, tiny bits of other minerals that got crushed into the diamond while it formed deep under the earth. However, if the facets have worn or rounded edges, bubbles, or if the gem looks rippled or pitted, it is probably glass. Those gems that are perfectly clear, with absolutely no inclusions, are probably quartz.
Finally, some common sense measures can prevent you from getting pressured to purchase a gem that turns out to be something other than a diamond. It shouldn't be ridiculously inexpensive, or you'll get what you pay for. It also will usually be mounted in an "open back" setting, which means that you can see around the rear of the gem and the back surface isn't coated with any silvery substance. Although it's true that diamonds are the hardest organic substance on earth, the infamous test of scratching diamonds across glass or metal might just give you a damaged diamond.
Even many gemologists cannot distinguish "real" diamonds from cultured diamonds. Cultured diamonds have been artificially manmade in a laboratory, not mined from mountains, yet they are chemically identical to those diamonds. Some companies are developing new kinds of identification methods for those who would like to purchase a mined diamond or for those that prefer a cultured one.

If there are holes in the back of the diamonds they are real. I've heard this many times over the years. Real diamonds also cut glass.

Well as long as you want to take the risk because if its not real it will ruin the stone.
rub it on concrete or use sandpaper, a real diamond wont get scratched.
They use to say that only a real diamond will scratch glass but zircons will scratch glass as well.
real diamonds cant be seen if you put in water and freeze it.

If it's that important to you, why not go to the jewelry shop? They will only take a few seconds to tell you.
Use the mirror in your makeup compact and run the stone alongside it. or if u have a softer stone like an opal, rub it against it. You will damage the softer stone, so it's best you go to a jeweler. Pawn shops will tell u it's not real hoping you'll give it to them and they can sell it higher.

If there is little holes in the back then it is real. That's how the diamonds breathe.

Take it to the local pawn shop. They have a diamond tester.

I don't know if you can. CZ are man made diamonds and only under a microscope is when you can tell they are not real.
