Method 1: dripping water. We can drop a drop of water on the diamond ring. If the water drops on the diamond ring don't go up, it's a real diamond ring. If it is scattered, it means it is synthetic diamond.
The second method of friction, diamond hardness is particularly high, we can use some rough paper to wipe the surface of the diamond ring, if scratches appear, it is artificial diamond.
The third method is the black line. We draw lines on white paper, because diamonds have high refractive index, the higher the refractive index, the stronger the reflective ability and the lower the relative perspective. If you put the diamond ring on the black line, if you can see the black line clearly, it is a fake diamond.
These three simple methods can easily distinguish the authenticity of a diamond ring.
After being buried underground for thousands of years, we finally got warm sunshine with the hands of human exploitation, and easily captured people's hearts with our inherent unique charm, and diamonds made a blockbuster. Human beings, especially women in human beings, hope that they can have a small diamond to illuminate themselves. However, this is an era of high imitation. How can people who like diamonds and want to buy them buy real diamonds? There are some simple methods to teach you to easily check the authenticity of diamond rings. Let's have a look.
Methods/steps
1/5 Step by step reading
First, drop a small drop of water on the diamond table. It is true if the water drops swell for a long time, but it is false if they disperse quickly. Because diamonds are lipophilic and hydrophobic.

Second, look at the fire color of your diamond ring. After polishing, the real diamond fire color is strong, and the brilliance emitted by those imitations with high refractive index is stiff and dim. Put the diamond in a white glass and fill it with water. If the light gets dim, it's a fake diamond. Secondly, it depends on whether the edges and corners of the diamond are very sharp. Only the edges and corners of imitations will be worn because the hardness is not high enough, and their edges and corners are blunt at best. At this time, you must rely on a magnifying glass to observe carefully. If you don't know how to choose two diamond rings that are not much different, put them together and compare them. Diamonds must be cost-effective.

3. Take a breath at your fancy diamond ring. The water mist condensed on the surface of real diamond will evaporate faster than that on imitation diamond, which is detected according to the principle of "high thermal conductivity" of diamond. If you want to buy diamond ornaments locally, you might as well bring a diamond imitation as a comparison of the experiment.

Fourth, choose a diamond ring, you can use your own stockings to test the workmanship of the diamond ring. A good mosaic should be a perfect fit. The best way to buy a diamond ring is to wear the diamond-encrusted side through the socks. If the jewelry is completely smooth when it passes through the stockings, it proves to be an excellent inlay process, otherwise it shows that the inlay is not tight enough.

5. Remember to check the diamond appraisal certificate when buying diamonds. It's a diamond ID card, a diamond with GIA diamond certificate, or a diamond ring with NGTC certificate. You can buy it with confidence. It is the two most authoritative appraisal certificates in China. NGTC is a mosaic grading certificate, and its requirements are even stricter than those of China's loose diamond grading certificate. When buying diamond ornaments in China, NGTC grading certificate is the best choice.
