Lab Grown Diamonds Description
Lab grown diamond is to artificially simulate the formation conditions of natural diamond, so that the carbon of non-diamond structure is transformed into the carbon of diamond structure. To put it simply, the raw material of graphite powder is transformed into diamond structure through high temperature and high pressure processing.
There are two main processes used to produce lab grown diamonds: high pressure and high temperature (HPHT) and chemical vapor precipitation (CVD). Since 1950, the high pressure and high temperature method was used for the first time to successfully synthesize diamonds, and now the main countries that use this technology to manufacture gem-grade synthetic diamonds are China, Russia, the United States and so on.

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
Prospects And Advantages Of Lab Grown Diamonds
Lab grown diamonds and natural diamonds, in the rough state are basically exported to India for processing and cutting, now India's diamond processing industry is quite famous in the world. The finished diamonds cut in India are exported to other countries for jewellery assembly and processing.
The difference is that there is a clear limit to how much can be extracted from natural drilling now that the technology is available. The yield of lab grown diamonds is, by comparison, infinite, and the huge difference in yield between the two is naturally reflected in price, provided that the difference can be identified. Gem-grade artificially cultivated diamonds have also been sold for many years in the market, and the most intuitive influence on its price is the rating of appraisal certificate. Appraisal companies in various countries have appraisal and certificate issuing services for artificially cultivated diamonds. In the world, artificially cultivated diamonds are known as "Laboratory Grown Diamond". China's national standard, called "synthetic diamond". That is to say, they are different in terms of volume, price and relevant standards. The relationship between natural diamond and cultivation of diamond is co-existence and win-win cooperation.
It is estimated that lab grown diamond jewelry, in the next one to three years, may be fully into the view of the majority of consumers. Part of the well-known businesses have also made the layout of lab grown diamond jewelry early, lab grown diamond and natural diamond consumption, further refinement and differentiation of target consumer groups, to better meet the people's growing needs for a better life tomorrow is coming.
