How are synthetic diamonds made?

The manufacturing method of synthetic diamonds is as follows:

In order to simulate the diamond production environment, diamonds are made of carbon. At 2300℃ and15 ~180,000 atmospheric pressure, a small natural diamond is placed in the center, surrounded by high-temperature metal liquid, and graphite is on the upper layer of the metal solution. In this environment, carbon atoms in graphite will be arranged from metal atoms to diamonds, forming new diamonds. However, the molecular structure of diamond manufactured by this method is not the complete octahedral structure of natural diamond, but a complex structure with limited volume.

Characteristics of synthetic diamonds

Synthetic diamonds are stable under long ultraviolet rays and show yellow-green fluorescence under short ultraviolet rays. Compared with natural diamonds, artificial diamonds can be said to be very good, and they will be more dazzling than ordinary diamonds.

The quality and appearance of synthetic diamonds are no different from those of natural diamonds. But at first, due to the lack of mature technology of synthetic diamonds, diamond dealers can use a very simple method to confirm whether diamonds are cultivated in the laboratory. They use powerful magnets because metal crystals are left in the planting process, and there are also powerful magnets inside artificial diamonds. Then the diamond can be sucked up.
