HOW ARE LAB-GROWN DIAMONDS MADE?
There are a few methods used to create lab-grown diamonds.
Typically, lab-grown diamonds start with a tiny lab diamond, like a
seed. The seeds are placed in a chamber called a plasma reactor (in
the case of CVD synthesis) or a large mechanical press (if
manufactured by HPHT). Then, depending on the technology used, some
combination of heat, pressure and a carbon source are used to make
the crystals grow, layer by layer.
The HPHT Method
HPHT stands for high pressure high temperature
This method mimics the conditions under which diamonds naturally
form. Large mechanical presses are used to apply extreme pressure
and high temperature to carbon in the presence of a diamond seed.
The seeds act as a template for a lattice of carbon to grow layer
by layer over the course of a few days.
