Product Description

                    

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.
