Lab Raw Uncut Rough Diamond Description


Synthetic diamond, also called the laboratory synthetic diamond, synthetic diamond. Using artificial methods to simulate the characteristics of natural diamond crystal, manufacturing diamond. The whole process using only the right amount of power and raw materials, environmental protection, laboratory manufacturing diamond, peaceful thoughts and the idea of green, is very popular in Europe and in young adults.

There are two main methods to produce synthetic diamond: high pressure and high temperature method (HPHT) and chemical vapor precipitation method (CVD). Since 1950, the first successful use of high-temperature high-pressure synthesis of diamond. At present, the use of the technology of production of gem grade synthetic diamond countries are China, Russia, the United States, etc.

In fact, cultivated diamonds, there are different grades 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 of gem grade diamond, production difficulty level and industry is a bowl of rice, if early artificial cultivation of gem grade diamond or coarse jade state, then the artificial cultivation of diamond, now it has been 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 methods for making lab-grown diamonds :CVD and HPHT.

Chemical vapor deposition is a method to promote diamond growth. CVD (chemical vapor deposition) diamond is based on the seeds. In high purity of methane, hydrogen, nitrogen and other gases, with the help of diamond molecules under high pressure of methane and carbon accumulation in the original diamond in microwave oven. 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 just like natural diamond, carbon as the main materials of high-tech synthetic diamond. Its hardness, density, thermal conductivity, brightness, sparkiness and fire color are almost the same as natural diamond.

Natural diamonds are created by nature, the result of billions of years of high temperature and pressure. Laboratory of rough diamond is produced in the laboratory, usually need a couple of weeks. The chemical difference is the same.

So how do you distinguish between rough laboratory diamond and natural diamond?

There is no discernible difference between rough lab-produced diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By magnifying, professionals will be able to recognize in the lab, growth and production of diamond inclusions nuances.
