Loose Lab Grown Diamonds Description

The lab grown diamonds uses advanced technology to simulate the formation conditions of natural diamonds under the earth's crust. This formation process is the main factor that distinguishes lab-created diamonds from mined diamonds. Lab-grown rough diamonds are synthesized in a few weeks, while the development of natural diamonds takes billions of years.
In the laboratory, there are two main processes for the manufacture of lab grown rough diamonds. The first one is the high-pressure high-temperature method (HPHT), The second one is chemical vapor deposition (CVD).
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.
Although both HPHT and CVD methods require the use of diamond crystal seeds to grow diamonds, they use different machines and scientific principles to grow laboratory diamonds. The laboratory-grown diamonds grown by the two methods have different shapes. It is easy to distinguish which is HPHT rough diamond and which is CVD uncut diamond.

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.
