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.
