How To Tell If A Diamond Is Real

People are enamored with the beauty of diamonds because of their property to bend light that passes through them. They are one of the most sought after luxurious gift for all occasions. However, there are a lot of simulated diamonds available in the market today which makes it a lot harder to recognize the real diamonds from the artificial ones. If the diamond you bought has a certification from GIA and AGS, you are guaranteed that your stone is real. But if your diamond was a gift or you inherited it and has no certificate to authenticate it, then knowing how to tell if the diamond is real becomes a bit trickier.

Here are some easy ways on how to choose a diamond that is real and authentic:


How to Tell If a Diamond Is Real


Magnification Test

Check your diamond under the lens of a microscope. Real diamonds must contain “inclusions” which are internal and external flaws. If your stone is a fake, it will not have any kind of flaws. This is because legitimate, natural diamonds are rocks that were formed inside the earth while fake ones are made in laboratories. This is one reason why fake diamonds are so flawless. Fake stones made out of cubic zirconia and moissanite are not exposed to the pressures of the earth while they are forming, and as a result, they don’t have those obvious flaws which are a characteristic of a real diamond.

Fog Test

Go to a place which is really cold and blow hot air on your diamond. Surround the stone with hot moist air. Since one characteristic of a legit diamond is it does not absorb heat well, your breath will not allow fog to accumulate on the surface of the stone. A fake stone will get fogged up immediately just like your mobile phone and correctional glasses.

Watch Covered in Real Diamonds

Heat Test

Get a pair of tweezers and hold the stone between them. Expose it to the direct heat of a burner or a candle for about one minute. Immediately drop it in cold water after being exposed to the heat. Real diamonds cannot be damaged by an extreme change in temperatures because they are made out of really strong materials. Fake diamonds will usually be destroyed or shattered after being exposed to severe temperature changes. If your diamond is unscathed after this test, then you deserve congratulations. However, you will need to clean the ash residues from the flame after the test. The best way to do this is to soak the stone in warm water with toothpaste for a couple of minutes. Gently scrub it with a toothbrush and rinse.

Conductivity Test

Most people don’t know that diamonds have the ability to resist electricity. Having your diamond be tested for its conductivity to electricity is very helpful in determining if it is real or fake. Fake diamonds made of moissanite can be seriously challenging to tell apart from legit diamonds because they have the same level of thermal conductivity. But moissanite will be able to conduct electricity while the real diamond will resist it. With the abundance of fake diamonds made of moissanite in the market, jewelry experts usually have a dedicated electric tool so they know how to tell if a diamond is real or fake.

Transparency Test

Real diamonds sparkle white and grey colors when exposed to light. This is called the diamond’s “brilliance”. While the rainbow light effect reflected off a real diamond is called “fire”. This unique feature of legit diamonds helps determine them from the fake ones. Try exposing your diamond to direct light and if you are able to see a colorful shine inside your stone, it will most likely be a fake. Another way to use the transparency test is with the use of a newspaper. All you need to do is to put the diamond on top of a newspaper. A real diamond’s brilliance should allow it to sparkle brightly keeping you from reading the text through the diamond. Fake diamonds will allow you to see through and read the newspaper texts.

In order to guarantee that your diamond is real, visit the nearest diamond shop and ask an appraiser to evaluate and inspect your jewelry. The appraiser will be able to tell if your diamond is genuine or a fake by using specialized tools. Always remember to ask for a certificate and a grading report when buying fancy diamond engagement rings. This will definitely put your mind at ease when the day finally comes that you have to get down on your knee.
