What are the methods used to make lab-grown diamonds

[navigupta]

Lab-grown diamonds are made with two methods in the diamond research lab

1. Chemical Vapour Deposition Diamonds
2. High-Pressure High Temperature

Chemical Vapour Deposition Diamonds (CVD )

A seed crystal is laid down in a small chamber in this process. The chamber is then topped up with gases that are heated. Once the gases reach the right temperature, the carbon layer begins forming on the seed crystal. This causes the seed to enlarge and create a square-shaped diamond crystal.

High-Pressure High Temperature (HPHT)

In this process, natural graphite is placed in a large machine that crushes it with extreme pressure and temperature. In this process, the graphite turns into a diamond.

Professional gold jewellers and gemologists use the microscope to look for the tiny differences in its inclusions that indicate how it was formed.

Lab-grown diamonds are created through methods such as High Pressure, High Temperature (HPHT), Chemical Vapor Deposition (CVD), Microwave Plasma Chemical Vapor Deposition (MPCVD), and Detonation Synthesis. HPHT involves subjecting a diamond seed to high pressure and temperature, while CVD and MPCVD deposit carbon atoms onto a diamond seed in a vacuum chamber. Detonation synthesis utilizes explosives to generate high pressure and temperature for diamond formation. These methods produce lab-grown diamonds with properties similar to natural diamonds in a timeframe of a few weeks to several months. for more information you can visit our blogs
