Single Crystal CVD Lab Grown Diamonds Description


Chemical vapor deposition (CVD) is a common method for making of thin film materials. It uses the chemical reaction of vapor precursor under specific conditions to deposit the required thin film materials on a specific substrate. In the preparation of single crystal diamond materials, methane and hydrogen are usually used as precursors to grow single crystal diamond by gas phase epitaxy at high temperature (about 1000 ℃), atmospheric pressure (1 ATM) or low pressure. The single crystal diamond substrates used can be natural diamond, HPHT diamond or CVD diamond.
The appearance and composition of CVD diamond are almost the same as that of natural diamond, and the physical and chemical properties are not very different. Under the naked eye, there is no difference between CVD diamond and natural diamond. However, the main reason why CVD diamond is valued is that it is "pure". Compared with natural diamond, CVD diamond is cleaner and has almost no impurities.

Single Crystal CVD Lab Grown Diamonds​ Introduction

Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The 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 Lab Grown Diamonds and natural diamonds?

There is no obvious difference between the 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.
