Synthetic HPHT Man Made Diamonds Description

Synthetic diamond is a kind of imitation of natural mineral, which is no inferior to the original stone. Is the diamond made in the laboratory real? Of course, they are! Man made diamonds have no defects and are cleaner and harder than natural diamonds.
Synthetic diamonds are produced in the laboratory in several ways. Manufacturing them requires expensive equipment and high-quality raw materials.
Several technologies are being used to produce laboratory grown diamonds.
The first method is called HPHT or thermogravimetry (temperature and pressure). The pressure diamonds produced in this way are relatively cheap because of the low cost. The bottom line is to heat (1500 degrees) carbon at high pressure (50000 – 70000 environments) with the help of catalyst metals.
CVD is a chemical vapor deposition method. CVD diamond grown by this method is used in optical and electronic fields. Hydrocarbon gas (methane) is deposited on silicon wafer by heating (3100 degrees) or microwave radiation. The film thickness is 2-3 mm.
Explosive fusion. Graphite produces an artificial replica under the high pressure of an explosive explosion.
Ultrasonic cavitation. Under normal conditions, graphite suspension was added into organic solvent, and artificial minerals were grown under ultrasonic cavitation.
High pressure and high temperature
Chemical vapor deposition
At present, the first two methods are the most popular.

Synthetic HPHT Man Made 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.
