How to identify the authenticity of diamonds Tips for identifying authentic and fake diamonds

Diamond is a very precious jewel. It is often made into various jewels for people to wear, and some fine diamonds also have excellent collection value. However, there are many fake diamonds sold on the market. People should pay attention to identification when buying them. If they are not careful, they will be deceived. So how should we distinguish the authenticity of diamonds? I will tell you in a moment.

1. Hardness test

Usually, when identifying the authenticity of diamonds, you can judge by its hardness. Because diamond is a naturally occurring mineral, its hardness is extremely high. Until now, no other material can surpass it. Moreover, nothing can leave scratches on the surface of a real diamond. If it is found that the surface of the diamond can leave marks during testing, it means that it is not a real diamond.

2. Thermal conductivity test

When identifying whether a diamond is real or fake, you can also perform a thermal conductivity test, because real diamonds have super high thermal conductivity. When identifying, people can breathe on the surface of the diamond. If you find that the water mist produced on its surface disappears quickly, it means that it is a real diamond. If the water mist on its surface evaporates slowly, it means that it may be a fake diamond.

3. Observe reflected light

Real diamonds are different from other minerals. A very fine frosted reflected light can be seen at the waist of this kind of mineral. However, when observing it, you need to use a magnifying glass. You cannot see it directly with your eyes. If you cannot see the reflected light with a magnifying glass, it means that the diamond may be a fake.

4. Water drop test

To identify the authenticity of diamonds, you can also use water droplets to test. You can drop water directly on the surface of the diamond. If the water droplets can maintain a spherical shape for a long time after reaching the surface of the diamond, it means that the diamond is real. If the water droplets disperse in a short time after contacting the surface of the diamond, it means that the diamond may be a fake.
