Lab Grown Loose Diamonds Description
Laboratory diamonds are diamonds cultivated by machines in the laboratory. After polishing and cutting, diamonds cultivated in the laboratory are no different from natural diamonds. Diamonds produced in the laboratory and natural diamonds are real diamonds. The main chemical composition of diamonds produced in the laboratory and natural diamonds is carbon.
At present, high temperature and high pressure method and chemical vapor deposition method are the two main methods to prepare laboratory diamonds.
Laboratory diamond forming machine can produce laboratory diamond through high temperature, high pressure and CVD technology. However, due to the different machines and technologies used in diamond production by high temperature and high pressure and chemical vapor deposition, people can distinguish diamonds produced by high temperature and high pressure and chemical vapor deposition from diamonds produced in the laboratory.
Fundamentally, synthetic diamonds and natural diamonds have basically the same physical properties, chemical composition and crystal structure as natural diamonds. But it cannot be called a fake diamond, diamond "growth" in the cultivation of trajectory and the natural diamond is different. The other is a simulation of natural diamond growth environment, grow in a few months.

From a scientific point of view, synthetic diamonds are identical to natural diamonds, the only difference being where they are formed.
Prospects And Advantages Of Lab Grown Diamonds
In recent years, diamonds have become more and more prosperous in the global diamond market, especially in the United States, the most mature market, and the Eurasian region has gradually followed suit. At present, artificially planted diamonds account for about 10% of the world diamond market, but the market demand is large, especially white diamonds with more than one carat. The natural diamond mines will be exhausted, and the main mineral resources will still have a service life of more than ten years. The supply of natural diamonds in the market will gradually be obtained by planting diamonds. Therefore, there is a large market space for planting diamonds. Coupled with the application of CVD diamonds in the civil industry, it will gradually mature and develop in recent years. The demand for jewelry diamonds is 10 ~ 100 times.
