Lab Created Diamonds Description
Artificial diamond is also known as laboratory grown diamond,
artificial diamond and natural diamond in chemical composition,
crystal structure, optical properties and physical properties of no
difference, only atomic structure level difference. The concept of
lab-made diamonds has only entered the jewelry market in recent
years, with many consumers questioning their identity and at one
point believing that lab-made diamonds were fakes. The government
responded that the lab-grown diamonds were not fake.
Compared with natural diamond, the biggest characteristic of lab
created diamond is unrestricted output and low price. In recent
years, with the continuous progress of technology, the yield and
quality of lab created diamonds have been significantly improved,
while the cost has further decreased.
In terms of production, According to Andrey Zharkov, the founder of
ULTRA C, who shared in the Special Forum of Lab created Diamonds
2019, the global production of jewel-grade rough cultivated
diamonds reached 6 million CT in 2019, and finished cultivated
diamonds reached 2 million CT, with an output value of about 800
million USD. Global production of lab created diamonds also grew by
15-20% in 2018 and 2019, with most of the growth coming from China,
bain & Company said in its global Diamond Industry Report 2019.
In 2016, the retail price of lab created diamonds was about 80% of
that of natural diamonds. In 2017, the ratio dropped to 65%, and in
2019, it further fell to 45-50% or less. For the cultivation of
diamonds with price as the main selling point, lower production
cost and price is undoubtedly a strong support for its further
expansion of market share.

From a scientific point of view, cultivated diamonds are exactly
the same as natural diamonds, the only difference being where they
are formed.
Lab-grown diamonds have exactly the same physical, chemical and
optical properties as natural diamonds, and have a hardness of 10.
