Lab Grown Colored Diamonds Description

 

Lab grown diamonds, also known as lab created diamonds or synthetic diamonds, are diamonds produced in a controlled laboratory environment. The diamonds cultivated in the laboratory have the same physical, optical and chemical properties as those mined by the earth. Laboratory diamonds have the same crystal structure of carbon atoms as natural diamonds, which makes them have the same superior hardness and spectacular beauty. The only difference between laboratory diamonds and mined diamonds is how they are made. The diamonds mined are formed in the earth's crust, while the diamonds made in the laboratory are made in the laboratory.
There are two methods of diamond growth in laboratory: chemical vapor deposition (CVD) and high pressure high temperature (HPHT).
In the HPHT method, diamond seeds (diamond fragments) are placed under extremely high pressure and temperature, similar to the way diamonds grow on the ground. The diamond seeds are put into the bulk carbon and placed under these conditions. The carbon melts and combines with the diamond seeds to form diamond crystals after cooling.
In CVD, they take a diamond seed (usually HPHT diamond) and place it in a chamber. They filled the chamber with carbon gas, which ionized into a plasma like substance, breaking down the bonded molecules. The carbon from these leaves forms around the seeds and begins to crystallize.

Lab Grown Colored 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.
