HPHT & CVD Method

Humans have truly achieved a horizon in disrupting how diamonds have been pursued over the years now. The traditional diamond mining practices have now been replaced by the innovative procedure of creating a diamond in a laboratory setting. Our lab-created diamonds are grown from micro carbon seeds of already existing diamonds. The two processes used to produce lab-grown diamonds are HPHT (high pressure high temperature) & CVD (chemical vapor deposition) using top notch technology in a controlled laboratory set up.”

HPHT Method

HPHT stands for ‘high pressure, high temperature’. HPHT diamond is created under extreme high pressures in an apparatus within a tiny capsule. Inside the capsule, the diamond powder dissolves in the molten metal flux and further, crystallizes on the seed for its synthetic diamond crystal formation. This crystallization process takes place over a period of few weeks to a month’s time to form one or a few crystals

CVD Method

CVD stands for ‘chemical vapor deposition’. CVD diamond is created inside a carbon gas (such as methane) filled vacuum chamber. A microwave beam inside the chamber further breaks down the gas molecules, so as to attract the carbon atoms onto the diamond seed plates placed below. This crystallization process takes place over a period of few weeks to form one or a few crystals at the same time, however, the quantity of the crystals is proportional to the size of the chamber and the number of seed plates. The crystals formed have rough black graphite edge which is removed using a heat treatment before the faceting of the gem.

Irrespective of the slicing method, lab-grown diamonds possess identical visual, chemical, and physical properties as that of a mined diamond. Moreover, they are environment friendly, requires zero mining, and human labor conflict-free. Lab-grown diamond is a technological achievement with a high value proposition and a high degree of accuracy, and we are proud to be making it an important facet of our business, today.”
