How Lab Grown Diamonds Are Made

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 the earth using one of two processes: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD).  

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.
