Well, real diamond is having property to cut the mirror.So you can check out by cutting a piece of mirror at home and you can easily detect that if the diamond is real or not...
The field test for raw diamond is 'extreme hardness'.
You take it to a jeweler who can test the stone and verify that it is a diamond, or that it is imitation.
Try cutting glass with it
DON'T heat test a diamoind. Leave it to a jeweller. If you apply heat to a diamond it will become soot (graphite).
No, breathing on a diamond will not reveal its authenticity. The fog test, which involves breathing on a gemstone to see if it fogs up, is not a reliable method to determine if a diamond is real or fake. Other tests such as using a diamond tester or consulting a professional jeweler are more accurate ways to verify a diamond's authenticity.

A better test is with a probe, which your jeweler will use to tell you if the diamond is a real diamond.

You can take the diamond and test to see if it can scratch glass(warning: this may cause damage to the diamond) also if you own a magnifying glass put the diamond up to it... If there are tiny imperfections it's most likely real, you could also literally smash it with a hammer... If it doesn't break or even chip, the diamond is real.

You may be able to determine whether or not a diamond is real at home by breathing on it to moisten the surface -- some people clean eyeglasses this way -- and if the stone remains foggy for more than a few seconds, chances are, the stone is not real. NB: This is an imperfect test and should not be relied on. However, be aware that the only way to truly identify a diamond is by use of a probe, which jewelers use to verify that the stone conducts electricity.
The field test for a diamond stone is its extremehardness. Lacking any tool to test extreme hardness, take the raw stone to a jeweler, who can use a probe to confirm that the stone is or is not a diamond.
A 'quick and dirty' test is to pass the diamond over glass. If it cuts the glass, it's probably a diamond. Some 'fake' diamonds cloud up under cold water; a real diamond remains clear. Finally, a certified gemologist will always be able to tell whether a diamond is a real diamond, or a 'fake' diamond -- using a diamond tester.
