Lab Grown Melee Diamonds Description

 

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.
Although synthetic diamonds have the same chemical composition as natural diamonds, the growth conditions of synthetic diamonds allow them to form their own identification symbols. Scientists use these identification symbols to distinguish synthetic diamonds from natural diamonds. Scientists can even use these symbols to determine the method used to grow diamonds.

HTHP and CVD are the two main methods for making laboratory-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.
During the CVD synthesis process, microwaves separate the hydrocarbon molecules entering the reaction chamber (left). These separated parts are deposited on the diamond seed at a lower temperature and attached to the surface of the growing diamond. Synthetic diamonds grow in thin layers, and their final thickness depends on the growth time. Like the HPHT diamond manufacturing method, the CVD manufacturing method is constantly improving, allowing manufacturers to create larger gems with greater improvements in color and clarity.

Lab Grown Melee 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.
