Loose Lab Grown Diamonds Description

 

Lab grown diamonds are diamonds grown in the laboratory using machines. After polishing and cutting lab grown diamonds are no different from natural diamonds. Both laboratory grown diamonds and natural diamonds are real diamonds. The main chemical components of laboratory-grown diamonds and natural diamonds are carbon.
At present, HTHP and CVD are the two main methods for making lab grown diamonds.

High temperature and high pressure method (HTHP) uses graphite as raw material, introduces suitable metal catalysts, such as Fe, Co, Ni, Mn, Cr, etc., and can synthesize diamond at temperatures above 2000K and tens of thousands of atmospheres.

Chemical Vapor Deposition (CVD) is a method of decomposing raw materials at high temperatures to produce active particles such as carbon atoms or methyl groups, and depositing and growing a diamond film on the substrate (substrate) under certain process conditions Methods.

Both HPHT and CVD can make lab grown diamonds by lab grown diamond machine. But people can distingush HPHT or CVD rough diamonds from the lab grown rough diamond shape because HPHT and CVD methods use different machine and technology to create diamonds.

At the beginning of 1930s, scientists discovered that certain types of diamonds have similar characteristics, so they divided diamonds into two categories based on the difference in transparency under ultraviolet radiation: Type I and Type II.

Loose 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.
