The difference between real and fake diamonds

There are three differences between real and fake diamonds: 1. The hardness of real diamonds is 10, while the hardness of fake diamonds is smaller; 2. The specific gravity is different. The specific gravity of real diamonds is 3.52, the proportion of fake diamonds imitated by zircon is 4.2, and the fake diamond imitated by moissanite is 3.22; 3. The properties are different. The hot air on the surface of real diamonds will soon disappear, and the hot air on the surface of fake diamonds will stay for a long time.

1, different hardness

Different hardness is one of the main differences between real and fake diamonds. Real diamonds have a hardness of 10, which is the hardest substance known in nature, while fake diamonds generally have less hardness and are prone to fragmentation.

2. Different specific gravity

The difference in specific gravity is also the difference between real and fake diamonds. The specific gravity of diamonds is 3.52, while the fake diamonds on the market are mostly imitations of zircon and artificial mosanite. Among them, the specific gravity of zircon is 4.2, and the proportion of mosanite is 3.22.

3, different nature

Judging from the nature of diamonds, natural diamonds have good heat conductivity and heat transfer. When one mouthful of hot air is directed at a diamond, the hot air on the surface will disappear quickly, while the hot air on the surface of a fake diamond will stay for a long time.
