How are lab grown diamonds made?
1 commentLab-grown diamonds are created under controlled conditions that emulate the natural processes responsible for the formation of earth-grown diamonds. Carbon undergoes high temperatures and pressures within a controlled environment, resulting in the production of diamonds. Lab Grown Diamonds are primarily made using two methods:
High Pressure-High Temperature (HPHT): Here, the carbon is pressurized and heated to over 2,700 Fahrenheit, enveloping a small diamond seed to form a new diamond.
Chemical Vapour Deposition (CVD): CVD involves a sealed chamber filled with carbon-rich gases, ionized into plasma, which adheres to a diamond seed to initiate diamond growth. Additional treatments may be applied to modify the diamond’s colour post-growth.
The diamonds formed by these two processes have the same quality and characteristics as that of a natural diamond. Additionally, since it’s made in lab conditions, the level of impurities is also very low as compared to natural diamonds that can collect impurities under the earth during formation.
