The very simplest and most effective way to identify if your diamond is real or fake. To test a stone to see whether or not it’s a diamond is to purchase a relatively cheap diamond tester. Otherwise, you might want to consider a higher-end, more costly tester that can also identify a wider range of diamond alternatives.
If you’re not close with a diamond’s structure and components, you may be led to think that a gemstone is a diamond when it is a different stone—like cubic zirconia or moissanite and for this reason. It is necessary to know how to identify a fake diamond.

There are following steps to identify your diamond real or fake.
The Scratch Test
Did you know that a diamond is one of the very strong substances on earth making it easy to cut through glass? Something like a scratch test could help you identify if the diamond under the question is, in fact, real.
If it scratches the glass, the chances are good that the diamond is real. But, it’s essential to know that the scratch test could damage your diamond in the process. It’s also not the most powerful way to see if your diamonds are real since other gemstones can have the same effect on the glass.
The Fog Test
A quick and easy way to identify whether a diamond is real or fake: try fogging it up with your breath. If it clears up after one or two seconds, then your diamond is real, but if it stays fogged for three to four seconds, the chances are that you’re looking at a fake diamond.
The reason for this: Diamonds disperse the heat instantaneously, producing it impossible to fog up while non-diamonds don’t have the same effect. For the test to work, make sure that your diamond is clean and that no oils are including the stone.
The Transparency Test
For this test, you will require a newspaper and a loose diamond. Place your diamond face down, with the pavilion facing up, on a section of text in a paper.
If you can read the letter through the diamond, the possibilities are that your stone is fake. But if the messages are blurry, this is one sign that your diamond is real. Make sure your diamond is clean before moving in with this test.
The Floating Test
This probably one of the most natural, although not conclusive, ways to find out whether your diamond is real or not. For the free test, you require a loose diamond and a glass of water.
If the diamond is real, it will drop to the bottom of the glass due to the large density of the stone. If the diamond is not original, it will float on the surface of the water. Not all artificial diamonds float in water, so don’t take the results of this test as conclusive.
The Fire Test
If you’re serious about seeing out whether your diamond is real or fake, you can put the stone through a fire test. Use a lighter to light the stove for around 30 seconds before dropping it in cold water. If it’s a real diamond, the stone will remain safe, but if it’s fake, it will shatter to pieces.
This will happen since lower materials are not able to handle the rate at which the materials expand and then contract due to the heat of the fire, unlike original diamonds that were produced under intense heat and pressure billions of years ago.
The Water Test
Use this easy test to assure a diamond is real or fake. Find an average-sized drinking glass and fill it ¾ of the way with water. Accurately drop the loose stone into the glass.
If the gemstone sinks, it’s a real diamond, and if it floats underneath or at the surface of the water, you have a fake on your hands.
An original diamond has high density, so the water test determines if your stone matches this level of density.
The Thermal Conductivity Test
In addition to a loupe, gemologists typically have a thermal conductivity probe or meter. They’ll use this tool to learn the thermal conductivity of a gemstone. Because diamonds are capable of heat conductors, the diamond will disperse heat rapidly after being warmed.
If the gemstone disperses heat at a slower rate, the diamond is not original. It’s worth noting that synthetic moissanite stones often have related or equal heat dispersement as real diamonds—making this test inconclusive with moissanite.
There are various diamond testers available out there, so you can decide whichever one you like the most.
The Black Light Test
When you place an original diamond underneath ultraviolet light, the stone with fluorescence in it will turn blue. But it’s necessary to know that this will only happen with about one-third of all diamonds.
A fake diamond, on the other hand, will rarely look blue under a black or UV light. This is not the most reliable test for those who would like to identify the actual status of their diamond.
Many of the tests in this guide, like the fog test and the thermal conductivity test, can help to identify, if your diamond is real or fake.
But due to the number and complexity of synthetic gemstone materials. We suggest consulting a diamond expert or jeweler to examine the pieces, you already have in your home. These experts are trained in recognizing how to identify a fake diamond.
If you’re using Gems Story diamond education or diamond experts for purchasing a diamond. You shall never have a problem knowing if it’s original or not. Any diamond you buy will come with a genuine GIA or AGS certificate. And all you require to do is ensure the diamond matches the certificate.
