HPHT Loose Diamonds Description

Lab Grown Diamonds, also known as man made diamonds, cultured diamonds and lab created diamonds, are grown in a highly controlled laboratory environment using advanced technology. These synthetic diamonds are made up of actual carbon atoms. Because they are made of the same material as natural diamonds, they have the same optical and chemical properties.

Can we distinguish between laboratory grown diamonds and natural diamonds?
Yes it is. However, only diamond professionals can identify the difference between laboratory grown diamonds and natural diamonds by using professional diamond identification equipment.

HTHP and CVD are the two main methods for making laboratory-grown diamonds.

High temperature and high pressure method (HTHP) uses graphite as raw material, introduces suitable metal catalysts, such as Fe, Co, Ni, Mn, Cr, etc., and can synthesize diamond at temperatures above 2000K and tens of thousands of atmospheres.

CVD stands for chemical vapor deposition, which is based on a natural bare diamond. With the assistance of high-purity methane, hydrogen, nitrogen and other gases, the carbon molecules in methane and diamond are continuously accumulated on the original diamond in a high-pressure way in a microwave oven. After layer by layer proliferation, transparent diamond as large as 10 carats can be formed.

HPHT CVD Loose Diamonds Introduction

​Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.

So how do you distinguish between Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
