Lab Made Diamonds - Two Popular Methods:

There are two processes used to create Lab-Grown Diamonds:

1. Chemical Vapor Deposition Diamonds

The first process is called Chemical Vapor Deposition (CVD). A “seed crystal”, which is a very small diamond seed, is placed in a small chamber. The chamber is then filled with gases that are heated. Once the gases reach the right temperature, layers of carbon begin to form on the seed crystal. This causes the seed to grow and create a square-shaped diamond crystal.

2. High Pressure High Temperature Diamonds

The second process is called High Pressure High Temperature (HPHT). This is meant to replicate the earth’s process of forming Natural Diamonds. In this process, natural graphite is placed in a large machine that crushes it with extreme pressure and temperatures. Under these conditions, the graphite turns into a diamond.


What is the Difference Between CVD and HPHT Diamonds?

You cannot tell the difference between a CVD and HPHT diamond with the naked eye. Both methods create a real diamond that is chemically and physically similar to natural diamonds. When it comes to grading Lab Grown diamonds, the same 4 Cs: Color, Cut, Clarity and Carat are applied.
