CVD Lab Grown Diamonds Description

Lab created diamonds are grown by simulating the growth environment of natural diamonds through high temperature and high pressure or chemical vapor deposition method. The chemical, physical, atomic, and optical properties of lab grown diamonds are the same as natural diamonds. we call them laboratory-grown diamonds.
CVD (Chemical Vapor Deposition) diamond is based on a loose natural diamond stone as the parent stone, using high-purity methane, plus hydrogen, nitrogen and other gases to assist, in a microwave oven at high pressure to make methane the same carbon as diamonds Molecules continue to accumulate on the rough diamond, and after a layer of proliferation, a transparent diamond as large as 10 carats can be formed.
Another method is HPHT(high temperature and high pressure), which uses metal elements as catalysts to simulate the temperature and pressure environment produced by natural diamonds for lab grown diamond growth.
As the first generation of diamond growth technology, high temperature and high pressure technology can completely simulate the growth process of natural diamonds, reproduce the reaction of the carbon layer on the ground, and convert graphite into diamonds.
At present, the popular high temperature and high pressure synthetic diamond equipment in the world mainly includes two side tops, six side tops and strip split ball or improved split ball.

CVD Lab Grown 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.
