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.
A disc containing 15-20 diamond seeds is placed inside the diamond growth chamber.
A plasma ball of superheated gases are created within the chamber
Heat in the chamber is put at about 900-1,200 degrees … not F, but C.
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.
Technicians will monitor the growth of those seeds, removing them from the chamber at the precise moment to maximize the gem’s characteristics.
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.
