CVD Diamond Process - How are CVD Diamonds Grown in Labs?

Limelight Diamonds | 2023

A thin layer of natural diamond is taken as the seed.

The same intense environment is re-created in the CVD reactor just like that found in the earth.

With the right combination of pressure and temperature conditions, rough diamonds are formed same as a mined one.
