CVD stands for “chemical vapor deposition” system.
The chemical vapor deposition system begins with a diamond “seed.”
A diamond seed is a small natural diamond fragment that can undergo extreme
temperature and pressure conditions. During the CVD process, the vacuum chamber
in which the diamond “seed” is placed fills with gases that are heavy in carbon
and is then heated to well over 1000 degree with intense heat then turns the gases into “plasma.”
For those of us who do not know, the plasma is what helps “build” the layers of the diamonds, making them into the lovely gemstones that we know and love so well.
