What are Lab Grown CVD Diamonds?
Lab grown diamonds are a new source of diamonds grown above earth. They have identical chemical, physical, and optical properties as diamonds from mines (mined diamonds). Lab grown diamonds and mined diamonds are the same material, Carbon (C), with the only point of difference being their origin.
Diamonds are formed when carbon atoms crystallize into cubic structures with tetrahedral bonds, making it the hardest substance on earth. This concept is used to grow diamonds above earth using High Pressure High Temperature (HPHT) process or Chemical Vapor Deposition (CVD) process. Diamond growth can occur only when a ‘diamond seed’ is present. A diamond seed is a very thin slice of diamond on which carbon atoms deposit to form strong tetrahedral structure and grows into a larger rough diamond.
