Artificial Lab Created Diamonds Description
Cultivation of diamond generation in the laboratory, the use of advanced technology and equipment in the laboratory to restore the natural diamond formation environment, the use of small diamond crystal seed induced diamond natural crystallization, in order to cultivate on the ground with natural diamond physical, chemical, optical characteristics of the same diamond. Therefore, lab grown diamonds is the real thing.
Someone once made a figurative analogy: natural diamonds are to lab grown diamonds, just as a naturally born baby is to a baby born by a surrogate mother, after all, it is human!
There are two methods for mass production of diamonds in the market: Chemical Vapor Deposition (CVD) and High Pressure High Temperature and High Pressure (HPHT).
The only difference between growing diamonds and mining them is the source, one in a lab, the other dug out of the ground.
There is no difference completely on the appearance oh, not through high-tech precision instrument identification is absolutely indistinguishable.

Artificial Lab Created Diamonds Introduction
What are the advantages of growing diamonds? It's official:
· Environmental protection: no large-scale destruction of terrain and ecology
· No conflict, guaranteed source: no child labor, exploitation, terrorist organizations, blood diamonds, pollution and other inhumane conditions
· All of them are Type IIa, whose quality is unspeakable, equivalent to the Top 2% of diamonds in the world.
According to data, in 2020, the global production capacity of cultured diamonds reached 6 million to 7 million carats, more than half of which came from China. Henan, in turn, produces 80 percent of cultivated diamonds in China. The cultivation of diamond industry in Henan is attracting downstream customers and investors to "dig gold", and is expected to win a voice in the cultivation of diamond industry for China in the world. It can be said that Henan is gradually changing the pattern of diamond industry, and has formed a diamond industry cluster integrating research and development, production and sales.
With the increasingly mature industrial technology, now the cultivation of diamond also began to accelerate the pace of marketization. The market position of cultured diamond has also been confirmed. In October 2020, GIA, the world's authoritative diamond appraisal agency, officially launched the cultured diamond grading certificate.
