The fog test
A diamond is very good at dispersing heat. If you hold the diamond up to your mouth and use the fog method like you would when cleaning a mirror, a diamond should evaporate the fog instantly. If the fog stays on the diamond for more than 3-4 second then you may be holding a fake diamond.

The rainbow test.
If you look closely at a diamonds sparkle, you should see beautiful shades of Grey reflections. If you see many rainbow reflections, you either have a very low quality diamond or a fake.
The UV test.
If you have a UV or Black light to hand then you might want to try this simple test. Place the diamond under the light in a dark room. If the diamond is real it should show a blue fluorescent glow. The absence of blue, however, does not mean it is fake, it could simply be a higher quality diamond. If you see a very slight Green, Yellow, or Grey fluorescence under ultraviolet light, it could possibly be a fake.
The flaw test
Diamonds tend to have tiny flaws in them such as small cracks, traces of carbon or pinpoints. These flaws are called inclusions and can effect the clarity of the diamond. The less inclusions in the diamond, the higher it scores on the clarity ranking chart. You can use a magnified glass to check for these tiny imperfections. If you can’t see anything, you either have a very expensive, rare diamond or a fake. You might want to get a professional jeweller to check this over for you.
