Lab Raw Uncut Rough Diamond Description
Synthetic diamond, also called the laboratory synthetic diamond, synthetic diamond. Diamond is generated and manufactured by simulating the characteristics of natural diamond crystal by artificial method. The whole process using only the right amount of power and raw materials, environmental protection, lab-created diamonds, peaceful thoughts and the idea of green, is popular among young people in Europe and the.
Artificial diamonds are produced by two main methods: high pressure and high temperature (HPHT) and chemical vapor precipitation (CVD). Since 1950, the high pressure and high temperature method was used to synthesize diamond successfully for the first time. At present, the main countries that use this technology to produce gem-grade synthetic diamond are China, Russia, the United States and so on.
In fact, artificial cultivation of diamond, have different grade and different USES. Industrial-grade synthetic diamonds are used in a wide range of applications, from well-known cutting to runway construction to decorative applications. Artificial cultivation and gem grade diamond, production difficulty and industry level is a bowl, if early artificial cultivation of gem grade diamond or coarse jade state, so artificial cultivation of diamond, now it has completely transformed, can hang on the elegant palace.

Lab Raw Uncut Rough Diamonds Introduction
Lab grown diamonds are also known as lab-made diamonds, synthetic diamonds and synthetic diamonds. There are two main ways to make lab-grown diamonds :CVD and HPHT.
Chemical vapor deposition is a way to foster the growth of diamond. CVD(Chemical vapor deposition) diamond is based on diamond seeds. In high purity methane, hydrogen, nitrogen and other gases, with the help of methane and carbon molecules in diamond under high pressure in the microwave oven to accumulate in the original diamond. Transparent diamonds can be formed by layer diffusion. The lab-grown diamond is of almost the same quality as a natural diamond. CVD diamond is a kind of high-tech synthetic diamond with carbon as the main material like natural diamond. Its hardness, density, thermal conductivity, brightness, flash and fire color are almost the same as natural diamonds.
There is also the HPHT(high pressure high temperature) method. HPHT was applied to gem grade cultured diamonds earlier, and as early as 2010, HPHT cultured diamonds appeared in the jewelry market. High temperature and high pressure diamond usually have high color, and CVD diamond usually have high definition.
