You need to know that if the proportion of natural diamonds is 3.52, then all natural diamonds will sink into the water, so when you see the stone floating in the water, you can see that this is not a diamond.

    The diamond also has a high refractive index. You can see that the higher the refractive index, the stronger the reflection of the light, so the relative perspective is relatively low. Then you can draw a straight line on it with a piece of paper, and then put the two unknown diamonds on it. Be sure to face them down and cover them on the straight line. Then you can see the straight line under the diamond, which means that this is not a natural diamond.

    The parental oil
    diamond has a "oil absorption" effect on oil. If it is a fake diamond, there is no such characteristic. You can dip a small amount of fat on your face and rub the diamond with your thumb.
