Lab Grown Colored Diamonds Description

There are two main methods to prepare synthetic diamond: high pressure high temperature method (HPHT) and chemical vapor deposition (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's mainly made of carbon. The quality of synthetic 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 of diamond growth by CVD. The basic principle is that methane decomposes in high temperature and vacuum, carbon atoms and hydrogen atoms are separated, and carbon atoms are deposited on the seed crystal to form diamond.
The purity and color of the diamond synthesized by CVD technology have reached the level of high-grade natural diamond, which is better than HPHT method to cultivate large grain diamond.
CVD synthetic diamond 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.

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 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.
