A lab-grown diamond is a real diamond that is created in a controlled laboratory environment.
This is achieved by replicating the natural process that forms diamonds deep in the earth. Lab-grown diamonds are composed of pure carbon, and share identical chemical, physical, and optical properties to that of mined diamonds.
There are two main methods to create lab-grown diamonds; High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
A small “seed” of a diamond is placed in a chamber and exposed to extreme pressure and heat, mimicking Earth's mantle conditions. Carbon atoms deposit on the seed, growing into a diamond over weeks.
A small “seed” of a diamond is placed in a chamber with carbon-rich gas, heated to high temperatures. Carbon atoms from the gas adhere to the seed, layer by layer. Both methods take weeks, compared to millions of years for natural diamonds. The result are diamonds that are indistinguishable from mined ones without the use of specialized equipment.
