CVD Lab Grown Diamonds Description

Laboratory diamonds, known as synthetic diamonds.
There are two ways to create rough lab-grown diamonds. One way is for scientists to use graphite on a huge machine, which smashes diamonds with extremely high pressure and high temperatures-just like when the earth formed natural diamonds. The high pressure high temperature (HPHT) process turns graphite into diamond. In the second method CVD, scientists put diamond "seed crystals" into a chamber filled with ordinary gas. When the gas is heated, they begin to form a carbon layer on the seed crystals, allowing them to grow and eventually form rough lab-grown diamonds. Generally speaking, the color grade of diamonds produced by HPHT is higher than that by CVD. Chemical vapor deposition (CVD) is a method to grow diamond from hydrocarbon gas mixture. The flexibility and simplicity of CVD devices explain the popularity of CVD growth in laboratory research. The advantages of CVD diamond growth include the ability to grow diamond on large area and different substrates, as well as the fine control of chemical impurities and properties of the diamond.

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 Rough 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 Rough Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the Rough 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.
