CVD Lab Grown Diamonds Description
The diamonds grown in the laboratory are also real diamonds. They have the same chemical composition and crystal structure as natural diamonds.
So how are cultivated diamonds made? Two methods are mainly used now. One is the high-pressure high-temperature method (HPHT), which creates high-pressure and high-temperature environments in laboratories to produce diamonds, which is to imitate the formation conditions of natural diamonds in the depths of the earth.
The second is chemical vapor deposition (CVD), which uses carbon-rich gas in the vacuum chamber of the laboratory to produce cultivated diamonds. The production process of the CVD process is to first decompose the methane gas molecules into carbon and hydrogen atoms, and then deposit them on the diamond seed crystals to form square flat cultivated diamond crystals.
It usually takes several weeks to manufacture cultivated diamonds in the laboratory.
The physical and chemical properties of laboratory-grown diamonds and natural diamonds are exactly the same as those of natural diamonds. Lab-Created diamonds are real diamonds.

CVD Lab Grown Diamonds Introduction
Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Rough Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.
So how do you distinguish between Rough Lab Grown Diamonds and natural diamonds?
There is no obvious difference between the Rough Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
