CVD lab-grown diamonds
Our lab-grown diamonds are produced using Chemical Vapor Deposition (CVD) technology.
​
On a substrate composed of a thin diamond strip, called a seed, carbon atoms are deposited in successive thin layers and taking the same crystal structure as the seed.
​
The original diamond seed thickens by carbon deposits, this is the growth of laboratory diamonds.
CVD technology results in lab-grown diamonds made of the same atoms, with the same structures and properties as natural diamonds.
