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.
