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.
"True" for culturing diamond is synthesized diamond: artificial cultivation diamond is through modern technology in the growth environment of laboratory simulation of natural diamond growth of diamond, and the properties of natural diamond, is a true diamond. Laboratory synthetic diamonds date back to the 1950s. There are two main methods for diamond production and laboratory manufacturing: high temperature and pressure (HPHT) and chemical meteorological deposition (CVD). Compared with natural diamond, lab created diamond in quality (provide bigger and more beautiful diamond), cost (only a third of the natural diamond prices), environmental protection (lab created diamond, save water, reduce the loss of land carbon emissions) have obvious advantages, etc. At present, diamonds grown in the laboratory have obtained IGI, GIA and NGTC national testing certificates.
The so-called "lab created diamonds", also called laboratory breeding diamond, diamond is also called the growth, called synthetic diamonds in the national standard. Lab-grown diamond products are comparable with natural diamond in terms of crystal structure integrity, transparency, refractive index and dispersion. As emerging in the field of diamond consumption choice, laboratory grown diamond products can be used to make diamond ring, necklace, earrings and other diamond accessories and other fashion goods.

From a scientific point of view, synthetic diamond and natural diamond exactly the same, the only difference is that the formation of their location.Laboratory breeding with natural diamonds are exactly the same physical, chemical and optical properties, hardness of 10.
