Lab Grown Diamonds Description
Grown Diamond refers to the lab-grown Diamond grown by scientists in the laboratory. Its composition elements, physical, chemical and optical characteristics are the same as those of natural diamonds, so it cannot be distinguished by naked eye, magnifying glass or even microscope. At present, there are two mainstream cultivation methods: chemical vapor precipitation (CVD) and high temperature and pressure (HPHT).
Characteristics Of Lab Grown Diamonds
The experimental cultivated diamond is manufactured artificially in the experimental selection of high technology, physical, chemical formula and optical reaction field and the development of naked diamond is 100 percent the same. The difference depends only on the form of origin. To put it simply, an experimental fabricated bare drill is a real bare drill, just like a developed and utilized bare drill. Both have only been manufactured in experiments, not taken out of mines.
It is likely that no one thought before the first year of AD, one day can be cultivated 100% true naked diamond - and underground growth conditions produced by the naked diamond, has the same optical reaction, biological and physical characteristics, so the cultivation of diamonds also choose the national standard 4C evaluation (color, purity, cut, carat), It also owns GIA/IGI/HRD/NGTC and other internationally famous diamond appraisal reports, and is subject to various appraisal institutions such as FTC and JCKNews.

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
Prospects And Advantages Of Lab Grown Diamonds
In the cultivation diamond industry, our lab-grown diamond color, clarity, product price is cost-effective, is a wise choice. From the experimental cultivation of diamonds into the human line of sight, in a short period of time in these years, the experimental cultivation of diamonds has been recognized by more and more people, as a daily wear, wedding a new purchase. Follow the taste of the spleen in recent years to lab grown diamonds the direction of diamond occupation, every time the topic conform to the trend, a new round of debate boom. Lab grown diamonds is in every aspect of the true meaning of the diamond, its chemical, physical, light and each of the characteristics of the same as natural diamond.
