Loose Lab Grown Diamonds Description

 

A laboratory-grown diamond is a diamond grown in a laboratory. They have the same chemical composition as natural diamonds and are optically identical. The biggest difference between natural diamonds and laboratory made diamonds is the way they are formed.

Natural diamonds have been formed under the earth's surface for millions of years, while laboratory grown diamonds can be made in the laboratory in a few weeks.

HTHP and CVD are two main methods for making rough lab grown diamonds.

HTHP: 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.

CVD: 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.

A simulated Diamond and laboratory made diamond are completely different. A simulated diamond is not a diamond at all, because its chemical properties are completely different. They can be made of anything from glass to cubic zirconia. Although they may look similar at first, diamond mimics are not as hard as diamonds or have the same optical properties as diamonds, so they show signs of wear and don't shine like diamonds.

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.
