How to tell the authenticity of diamonds?
Tips for distinguishing genuine and fake diamonds;

1, drop method

Natural diamonds are hard and delicate. Drop a drop of water on the surface. If it is a real diamond, the water droplets will persist for a long time, or breathe towards its surface, and the water vapor on the surface of the real diamond will soon disappear. Otherwise, it is a fake diamond.

2. Hardness test

Natural diamond is the hardest gem in nature, and carving on its surface with a sharp knife will not cause any scratches. However, the hardness of fake diamonds is low, and traces are easy to appear on the surface after carving.

3. Look at the color of the fire

Under the irradiation of light, natural diamonds have a dazzling fire color, and their surfaces can reflect colorful light, while the luster of fake diamonds is stiff and dim, which looks unnatural.
