How Are Lab-Grown Diamonds Created?

Just how are lab-grown diamonds created? Think about it like that middle school experiment where you learned to grow plants under a light bulb. With some advanced knowledge of the Periodic Table to boot!

As you’d expect, lab-grown diamonds are produced under laboratory conditions. The two artificial processes through which they are created are known as High Pressure, High-Temperature process and Chemical Vapor Deposition process (HPHT and CVD).

Both methods will lead to the same result: a diamond identical to one created through geological processes that exhibit the same fire, scintillation, and sparkle. When the diamond mounted on a lab-grown diamond ring has the HPHT or CVD demonition specified, this is to indicate the exact method of production.

How it Works

Here’s a quick overview of how the process typically works and the steps your lab-grown diamond takes during its evolution.

Step 1:

A disc containing 15-20 diamond seeds is placed inside the diamond growth chamber.

Step 2:

A plasma ball of superheated gases are created within the chamber

Step 3:

Heat in the chamber is put at about 900-1,200 degrees … not F, but C.

Step 4:

This causes methane and hydrogen gases to stick to the aforementioned seeds. The diamond will the grow, atom by atom, over the next couple of weeks.

Step 5:

Technicians will monitor the growth of those seeds, removing them from the chamber at the precise moment to maximize the gem’s characteristics.

Step 6:

The 15-20 cubic-shaped rough diamonds are sent to a gemologist to be cut and polished.

As a result of this method of creation, these gems are labeled as lab-grown, lab-created or manufacturer-created. These labels are required by the Federal Trade Commission to make consumers aware that they’re purchasing an ethically sourced, lab-grown diamond.
