CVD Lab Grown Diamonds Description

Diamonds are made of pure carbon in the shape of a tetrahedron. Diamonds are famous all over the world as luxury and precious jewelry. However, it is also the hardest substance in nature, a good heat conductor and an inert substance. These characteristics mean that diamonds can play an important role in some industrial applications, such as metal cutting, drilling, grinding, mining and construction, as well as applications in high-pressure testing and high-performance bearings.

For a long time, people believed that diamonds could only be "man-made" under high pressure and high temperature conditions, imitating the formation of natural diamonds. The use of this method to make diamonds is now very common, mainly for the aforementioned industrial applications. However, in the late 1980s, scientists discovered how to use a method called chemical vapor deposition (CVD) to "plant" diamonds.

Diamonds produced by CVD are produced by mixing hydrocarbons, usually methane, with hydrogen in a low-pressure vacuum chamber. The diamond will grow in a few days until it reaches the size required for the specific application. This process requires a constant, stable and reliable source of hydrogen, which makes Peak's hydrogen generator an ideal solution.

Normally, when methane and hydrogen are mixed, carbon is produced in a non-diamond form, such as graphite. In the CVD chamber, microwave energy, electric discharge, or hot cathode is used to generate hydrogen atoms, which react with non-diamond carbon to form vapor. Highly active hydrocarbon vapors will further react with hydrogen atoms, resulting in the separation of hydrogen and pure carbon, and pure carbon is deposited as diamonds. With the repetition of this process, the diamond can grow into different sizes according to the required application.

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.
