Such a good thing, the average person will not believe it. It is natural that the diamond ring should be returned to its original owner, but how to judge whether it is a real diamond ring or a prop? How to tell whether a diamond is genuine or not? Here are four ways to identify the authenticity of diamonds.
The first and simplest way to tell whether a diamond is genuine or not is to rub it back and forth on fine sandpaper several times. If it has scratches on its surface, it is a fake diamond; if it has no scratches, it is a real diamond.
The second way to tell whether a diamond is genuine or not is also very simple. Drop a small drop of water on the diamond. If the water drops swell for a long time, the diamond is real; if it disperses quickly, it is fake. This is because diamonds are oleophilic and hydrophobic. Or you can put a little oil on your face and rub the diamond with your thumb, which will make your thumb feel sticky, while fake diamonds will make your thumb feel slippery.
The third way to tell whether a diamond is real or not is to put it in front of your mouth and take a deep breath. If the fog stays for a long time, a few seconds, the diamond is probably fake. Because real diamonds dissipate heat quickly, it is not easy to fog. Even if you breathe first and then look, real diamonds are still much clearer than fake diamonds.
The fourth way to tell whether a diamond is genuine or not is to check it with a magnifying glass. Natural diamonds often have some small flaws, which can be seen through a magnifying glass. What you look for through a magnifying glass is a defect formed by minerals, or a very subtle different color. These two phenomena are one of the evidences that diamonds are real. Although this diamond may not be perfect, at least it is true. Fake diamonds have no small flaws and subtle color unevenness of natural diamonds.
