How to identify true and false diamonds
The authenticity of diamonds can be identified by the drip method, the breath method, the adsorption or white paper marking method.
Drip method
Drop a small drop of water on the diamond. If the water drop bulges up and keeps the shape of the ball for a long time without dispersing, it is true; and if it disperses quickly in a relatively short time, it is a fake or imitation. The characteristics of diamonds are lipophilic and hydrophobic.

Haqifa
Take a breath at the diamond. If the moisture on the diamond disappears quickly, then it is a real diamond; if the moisture on the diamond disappears after a period of time, it is an imitation. Because the water mist condensed on the surface of the real diamond will evaporate faster than the water vapor on the fake diamond, this is the use of the diamond’s “high thermal conductivity” principle.
See adsorption or white paper marking method
We all know that diamonds have strong grease and other adsorption properties. Touching diamonds with fingers will have a sticky feeling, which is not found in other gems. Or draw a black line on white paper and place the diamond table on that one. Online, if the line is not visible, it means the diamond is real, otherwise it is fake.

How to identify diamonds with what light
First of all, when buying diamonds, we can write a few words on a piece of white paper and look through the diamond. If the words can be seen through the diamond, it means that the diamond is fake. If you can’t see the words, it means the diamond is real and worth buying. When buying diamonds, “reading the word” is our first good way to determine the authenticity of a diamond.

Secondly, look at the dispersion and luster of the diamond. Generally speaking, the luster of real diamonds is very good, very agile and vibrant, while the luster of fake diamonds is relatively dull and rigid. At the same time, dispersion mainly refers to the degree of dispersion of diamonds. Real diamonds will only glow blue and orange. Therefore, when buying diamonds, everyone needs to carefully check the color of the diamond.
