Lab Created Diamonds Description
Lab-grown diamonds are also known as lab-made diamonds, synthetic diamonds and synthetic diamonds. There are two main ways to the growth of diamond manufacturing laboratory: CVD and HPHT.
Artificial diamond simulates the growth of natural diamond in the laboratory environment through modern technology, and has the characteristics of natural diamond, is the real diamond. The history of laboratory synthetic diamonds dates back to the 1950s. There are two main manufacture diamond production and laboratory methods: high temperature and high pressure (HPHT) and chemical vapour deposition (CVD). This formation process is the main factor that distinguishes lab-made diamonds from mined ones. Lab-grown diamonds can be mass-produced in a matter of weeks.Compared with natural diamond, laboratory synthetic diamonds in quality (provide bigger and more beautiful diamond), cost (only a third of the natural diamond prices), environmental protection (laboratory synthetic diamonds, save water, reduce the loss of the terrestrial carbon emissions) have obvious advantages, etc. At present, diamonds produced by the laboratory have obtained IGI, GIA and NGTC national testing certificates.
The so-called "lab created diamonds", also say laboratory breed diamond, also say grow diamond in national standard, say man-made diamond. Laboratory of diamond products in crystal structure integrity, transparency, refractive index and dispersion can be equivalent to that of natural diamond. As the emerging field of diamond consumption choices, laboratory breeding of diamond products can be used to make diamond ring, necklace, earrings and other diamond jewelry and other fashion goods.

The Difference Between Lab Diamonds And Natural Diamonds
Lab-grown diamonds are chemically, optical and structure are the same as the mining of diamonds. What is the meaning of this?
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. Both on the chemistry of the difference is the same.
There is no discernible difference between rough lab-produced diamonds and natural diamonds. Even professional gemologists also need special equipment to identify them. By magnifying, professionals will be able to recognize in the lab, growth and production of diamond inclusions nuances.
From a scientific point of view, synthetic diamond and natural diamond exactly the same, the only difference is that the formation of their position. Laboratory cultivation of natural diamonds has exactly the same physical, chemical and optical properties, hardness of 10.
In fact, in terms of shape, lab-made diamonds and natural diamonds usually take on different shapes. Due to different formation conditions, natural diamonds are usually octahedral crystals, that is, eight equilateral triangular crystal faces, while cultivated diamonds are usually grown into crystals containing both octahedron and cube, that is, six square crystal faces. Therefore, it is easy to distinguish from the exterior.
