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 lab grown diamonds and natural diamonds are real diamonds. The main chemical components of lab grown diamonds and natural diamonds are carbon.
Lab grown diamonds is usually produced by chemical vapor deposition (CVD) or high pressure high temperature (HPHT) methods.

HPHT synthetic diamonds usually contain metal co-solvent inclusions, which are black and opaque under transmitted light, and appear metallic under reflected light. This is because during the growth of HPHT diamonds, metals used as catalysts sometimes enter the diamond crystals. These co-solvent metal alloys contain elements such as iron, nickel, and cobalt.

CVD synthetic diamonds do not contain metal inclusions. But they usually contain dark graphite inclusions or other mineral inclusions, which are formed during their unique growth process. Graphite inclusions are different from metal inclusions in that they have no metallic luster. The CVD process is very different from the formation of natural diamonds. In a vacuum chamber filled with a hot mixture of hydrocarbon gas and hydrogen, extremely low pressure is applied, and diamonds are produced. Under normal circumstances, heating the mixture at such low pressures will produce graphite or some other non-diamond form of carbon. But in the CVD growth chamber, some of the hydrogen is converted into hydrogen atoms, which promotes the formation of diamonds, because diamonds are more stable in this environment. The conversion of hydrogen molecules into hydrogen atoms is accomplished by the application of microwaves, electric discharges or hot wires.

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.
