CVD Stands for Chemical Vapor Deposition
Lab-grown diamonds are diamonds that were grown by scientists in a lab.
They share the same chemical makeup as natural diamonds, and are optically identical.
The biggest differences between natural and lab-created diamonds are how they're made, and how rare they are.
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 a grow layer by layer over the course of a few days.
How Long Does It Take to Grow a Diamond?
In nature, it takes millions of years for diamonds to form. In a lab, we can grow a one carat stone in about two weeks.
How Do You Make Colored Lab-grown Diamonds?
One of the great advantages of lab-grown diamonds is that they can be made in an array of colors that are very rare when found in nature.
This is achieved by making changes in the gas mix added to the CVD reactor combined with treatments to these stones applied at the end of the synthesis process.
The process sounds simple, but it has taken our scientists thousands of hours to refine the process and create the perfect Diamond Monster shades of light pink and blue every time.
