Yuda Crystal 3.0 - 4.0 ct White VVS VS HPHT Rough Uncut Diamonds Artificial Lab Created Diamonds

Artificial Lab Created Diamonds Description

There are two main processes to make artificial diamond: one is high pressure and high temperature method (HPHT), the other is chemical vapor deposition method (CVD).

High temperature and high pressure catalytic technology (HPHT) simulates the natural environment in which diamonds form 150 kilometers below the earth's surface. At about 2000 degrees Celsius and 5.8 atmospheres of high temperature and pressure, the crystal structure of diamonds will be dislocated, or tiny graphite will be used to make synthetic diamonds. It is mainly made of carbon. The quality of artificial diamonds is almost the same as that of natural diamonds.

In theory, diamonds need to be produced under high pressure. Chemical vapor deposition (CVD) is a method to cultivate diamond by CVD. The basic principle is that methane decomposes in vacuum at high temperature and vacuum, carbon atoms and hydrogen atoms are separated, and carbon atoms are deposited on the seed crystal to form diamond.
The diamond synthesized by CVD technology can reach the purity and color of high-grade natural diamond, and can cultivate large grain diamond better than HPHT.
CVD Artificial Lab Created Diamonds can be used in jewelry industry and industrial cutting. With the progress of technology, color and purity are improving, and the output will be larger and larger, which can provide more choices.

Artificial Lab Created 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.
