There are two common methods of producing lad diamonds: the HPHT (High Pressure High Temperature) method, High Temperature High Pressure method, and the CVD (Chemical Vapor Deposition) method. The basic principle is that scientific researchers simulate the growth environment of natural diamonds and use science and technology to deposit carbon ions little by little with the assistance of methane, hydrogen and other gases at high temperature and low pressure. With the development of science and technology, the fastest time to generate a cultivated diamond of about 1 carat is currently only 5-7 years. In contrast, under the compression of nature, the growth cycle of a natural diamond takes millions or even hundreds of millions of years.
