Today, people are becoming aware of the exploitations that are frequently occurring in the diamond mining industry. A conscious customer will go for alternate diamond options like lab-grown diamonds. Lab-grown diamonds are just as solid as those found in mines, despite the obvious differences between them and naturally mined diamonds.
A diamond that is created in a laboratory setting is called a lab-grown diamond. Both lab-grown and naturally mined diamonds have similar physical, chemical, and optical properties.
Mainly two different processes are used for creating diamonds in a lab. One method is the High-Pressure High Temperature (HPHT) and the other one is Chemical Vapor Deposition (CVD).
In this article, we will take a look at the CVD process for the creation of lab-grown diamonds. Read along to know more about this process.
What Is The CVD Process?
As we have mentioned, CVD stands for chemical vapor deposition. The method starts with a diamond seed, which is a little natural diamond fragment that can withstand high temperatures and pressures. For lab diamond formation, selecting the hardest and highest-grade natural diamond bit is critical.
A vacuum chamber is filled with carbon-rich gases before the diamond seed is added. For the CVD procedure, it is then heated to over 1000 degrees. Due to the intense heat, the gases transform into “plasma.” For those who do not know, the plasma is responsible for helping “build” the layers of diamonds, turning them into the lovely gemstones we know and appreciate.
How Much Better Are CVD Diamonds?
This question doesn’t have a clear-cut answer. Using the CVD technique, diamonds of varying grades can be produced. The fact that lab-created diamonds are superior to naturally occurring diamonds is something we can be certain about. This is so because natural diamonds are continually exposed to gases or substances during their development that might degrade their quality. On the other hand, a diamond of greater grade is produced through a successful CVD procedure.
How Can I Be Sure My Lab Diamond Was Created Using CVD?
In order to verify that your lab-grown engagement ring containing diamonds is conflict-free and that it has all the qualities that the producers claim, you need to request the diamond certificate when you purchase it. The diamond certificate will typically contain information about the procedure used to make the stone.
