How to Tell If it is a Real Diamond?

This guide will help the people who have ring collections or pieces and need to identify if they are genuine or not. If you have some ring pieces that you want to authenticate, then this guide will let you know, using at-home tests, as well as some tests that a diamond professional can conduct with the specific equipment.

The easiest yet the most effective way to test a stone is to observe if it is a genuine diamond or not by using a relatively inexpensive diamond tester. Or you might need a more highly expert tester who can also identify a wide range of diamond options.

If you are unfamiliar with the diamond components and structure, you might believe that your jewel is a diamond while it is a completely different stone like Cubic Zirconia. So, it’s essential that you know how to identify a counterfeit diamond.

This guide will help you to perform some of the practical at-home tests, which are essential. All the diamond professionals have enough experience with the proper equipment to identify if your diamond is a genuine or a fake one.

Some of the different methods to find if the Diamond is a genuine or not are:

Water test

You can just simply try to use this test to verify if the diamond is genuine. Take a glass and fill it ¾ with the water and then carefully drop a stone in the glass.

If your diamond is genuine, it will sink. If it floats below or at the water surface, it is a fake diamond.

The reason for this is, a genuine diamond will always have a higher density than the water, and the water test will show if the gemstone matches the density level.

Heat Test

For the heat test, take a glass and fill it with the cold water. Wear heat-proof gloves while holding that stone. Then heat the stone using a lighter for around 40 seconds.

After that, drop the stone straight in the cold water. If the stone shatters, it is made from the lower components, and it is not a genuine diamond because the diamond will not show any reaction.

This tactics tests the strength and quality of your stone. Due to the quick contraction and expansion of the heat, weaker materials like the Cubic or glass will break or crack.

As diamonds are among the strongest materials that exist on the planet, they are resistant to these heat tests. The heat will disperse quickly, and your diamond will not have any effects on the temperature change.

The reason for the same is that diamonds are made from very strong materials, so they are resistant to any kind of high heat.

Fog Test

For the fog test, just hold your diamond or ring between your fingers, breathe on it and throw some air there. A slight amount of fog will be created on the diamond because of the moisture and heat of your breath.

If fog dissolves immediately, then you have a genuine and real diamond. If it takes a few seconds to dissolve, it might be a fake diamond.

The reason is that diamonds efficiently conducts the heat, so it disperses quickly.

UV Light Test

If you want to test the diamond in another way, then simply place it under a UV light to observe the reaction. The majority of the diamonds will release a blue-colored glow. Moreover, some diamonds would not glow under the UV light. If a stone does not glow, the results would not necessarily suggest that its fake.

If this test is not conclusive, the best option is to have a diamond jeweler or experts use their advanced equipment for testing the stone.

Mount & Setting Test

If a diamond is placed in a diamond engagement ring, then you need to check the mount and settings used in them.

Due to a diamond’s expensive price tag, a genuine diamond will come with high-quality jewelry. For instance, a genuine diamond is always fitted with materials like platinum, white gold, yellow gold surface, or side stone settings such as halo engagement rings.


How do you tell if a diamond is real without a tester?

Testing Mounted Diamonds. Use the fog test. All you can do is put the stone in front of your mouth and fog it like you would a mirror. If it stays fogged for a couple of minutes, it is probably a fake one – a real diamond disperses the heat from your breath instantaneously and would not fog up easily.

How much is a 1-carat diamond?

In general, a 1-carat diamond cost between $2000 – $12000. The cost depends on factors such as Cut quality, the shape of the diamond, and color.

Do real diamonds float or sink?

Real diamonds sink in water, as they are denser than water. But fake ones float as they can’t match their density with the real one.

Does a real diamond sparkle rainbow?

No. Real diamonds doesn’t sparkle rainbow. They sparkles white light when checked under white light. But, if your diamond is sparkling rainbow , then it might be Cubic Zirconia.
