CVD Lab Grown Diamonds Description
Lab diamonds, also known as cultured diamonds and synthetic diamonds. Nowadays, there are two main methods to create lab grown diamonds. The two methods are HPHT and CVD methods.
HPHT means High pressure high pressure. It imitates the formation process of natural diamond, puts seeds under great mechanical pressure, and exerts great pressure and high temperature on ready-made carbon. Seeds will quickly turn into diamonds with carbon lattice and grow layer by layer in a few days until they reach the desired carat weight.
Another method called chemical vapor deposition (CVD) is to inject carbon-containing gas into a vacuum chamber and deposit its crystals on synthetic diamond seeds. This method requires lower temperature and lower pressure than the high-pressure high-temperature method. Both methods are currently very popular diamond manufacturing methods. The initial equipment cost of using the chemical vapor precipitation method to manufacture diamonds is lower than that of the high-pressure and high-temperature method, but the diamonds manufactured using this method require subsequent processing to improve the color.

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 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.
