Certified 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.

There are two main methods to make Rough Lab Grown HPHT Synthetic Diamond: one is high pressure and high temperature method (HPHT), the other is chemical vapor deposition method (CVD).

For a long time, people believed that diamonds could only be created under high pressure and high temperature conditions, imitating the formation of natural diamonds. However, in the late 1980s, scientists discovered how to use a method called chemical vapor deposition (CVD) to grow diamonds.
Colorless and almost colorless CVD synthetic diamonds are usually type IIa, Type IIa diamonds are characterized by high purity, and they exhibit transparency in certain parts of the ultraviolet and infrared spectra.

For consumers, a professional diamond certificate can clearly show the detailed characteristics of the diamond. So that people can clearly know the quality of the diamonds they buy.

Certified 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.
