CVD Lab Grown Diamonds Description

 

What is a lab-grown diamond?
Lab diamonds are real diamonds. Lab-grown diamonds after polishing and cutting are no different from natural diamonds. Carbon is the main element of natural and laboratory-grown diamonds. Lab-grown diamonds are diamonds grown in the laboratory using equipment that simulate the growth environment of 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.
Beginning in the 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. Subsequently, the scientists further divided type I and type II diamonds into two sub-categories: type Ia, type Ib, type IIa and type IIb through the arrangement of carbon atoms and impurity atoms in the diamond structure.
Most synthetic diamonds are of type Ib, IIa and IIb.

HTHP and CVD are the two main methods for making laboratory-grown diamonds.

First of all, what are HTHP and CVD?

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.

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.
