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.
