Synthetic Lab Grown Rough Diamond Description


Synthetic diamonds and laboratory grown diamonds are the same. They're real natural diamonds, but they grow in weeks, not billions of years, like mined diamonds.
They have the same optical and physical properties. The main difference between the two diamonds is their origin. 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.

Synthetic Lab Grown Rough Diamond 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.
