The best way to identify a diamond is to use a diamond tester. It is a handheld device which sends a thermal beam (heat) inside the stone and reads how fast the stone conducts the heat. Each mineral has a different heat conductive coefficient so this way you can tell a diamond from other stones.
However, a moissanite (a withe stone grown in the lab) has the same response as a diamond so a diamond tester may confirm the moissanite as a diamond.
Recently, a moissanite tester has been developed , so it can differentiate a diamond from a moissanite. Also a moissanite turns deep yellow when heated with a torch then turns back to white when cools down.
Also, it is possible that a trained eye can see a greenish color it the moissanite.

What is engraved on diamonds?
Lasers -- or fine-tipped diamond tools -- can engrave characters or images on diamond stones. Sometimes this is done to identify an individual stone. Note, however, that any engraving on a diamond can be polished off the stone.
What does a symbol of a diamond stamped inside a ring mean?
Jewelery stores sometimes add stamps and icons inside rings to identify their prices.
How can you tell the difference between diamonds and moissanite?
Moissanite presents an interesting alternative to diamonds, insofar as gem-quality 'bling' is concerned. Some describe it as a substantive alternative to diamond many times more valuable than other diamond alternatives. Because of natural moissanite's innate physical and chemical properties, it is difficult for the untrained eye to identify as different from diamonds. A certified gemologist will always be able to identify moissanite, because its base composition from silicon carbide is fundamentally different from a diamond's composition of carbon. You can read more about moissanite and diamond, below.
How do you identify a diamond?
With every diamond comes a certificate
How do you identify a rough diamond?
The field test for diamond is 'extreme hardness'.
How can you tell if your diamond is genuine?
A genuine diamond can be natural or lab-created. A certified gemologist can help you identify the source of your diamond, and whether the diamond is indeed a diamond.
How do you identify a raw diamond?
In the field, you can identify a raw stone because of its clarity and its extreme hardness.
Does a diamond marking pencil identify a diamond?
Diamond engraving pencils are specially designed for professionally engraving and writing on glass microscope slides.
What is a green diamond?
A green diamond is a diamond in possession of a shade of green. A gemologist can help you identify the source of its colour -- whether natural or treated.

How do you identify good diamond?
'Good' is a judgement and you are the judge. A 'good' diamond could be a perfect, flawless, diamond, as in a 'good' investment. Or a 'good' diamond could be a family heirloom, worn by several generations of fabulous women.
Are colored diamonds radiated or irradiated?
No, for a naturally coloured diamond, and yes, for a treated diamond with enhanced colour. Any diamond can be treated, either chemically or by radiation, to enhance its natural colour. Many naturally coloured diamonds require no treatment, because their colour is judged to be naturally ideal. A certified gemologist can identify a naturally coloured diamond, and can also identify and describe treatments to a diamond intended to enhance its natural colour.
What methods do you use to identify diamonds?
The field test for diamond is extreme hardness. Other tests include the use of a probe, which jewelers use to identify diamonds.
How can you read the clarity of a diamond?
Trained gemologists use a 10x magnification to identify diamond clarity. You can read more about how clarity is graded by understanding the flaws and how they occur, below.
Are cut diamonds marked?
Yes, finished diamonds may have a lasered inscription, or other mark created by another diamond. Usually, these are used to identify or brand a diamond.
