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.
