CVD Lab Grown Diamonds Description

 

What is a laboratory rough diamond?

First of all, from a physical point of view, diamond is a carbon elemental crystal and its composition is the same as that of coal and graphite. However, although the coal and graphite we see in our lives are all black, diamonds are not black at all. They are transparent. This is because diamond, as a crystal, has a special energy band structure for the electrons inside. This structure determines that it will not absorb the energy of visible light, so visible light can pass through the entire diamond, making the diamond appear transparent.
Lab-grown diamonds have been used in industry for more than 50 years, but in the past ten years, their quality and price have improved significantly, which means that these lab-grown diamonds can now be used in jewelry.

Generally speaking, Lab Grown Diamonds grown in the laboratory are almost no different from natural diamonds, and it is difficult to distinguish them with scientific instruments. In essence, Lab Grown Diamonds and natural diamonds are actually a kind of thing, but they are produced in different ways.

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.
