CVD Lab Grown Diamonds Description
The physical properties of CVD synthetic diamonds are the same range as natural diamonds in terms of hardness, thermal conductivity, and strength. Therefore, CVD synthetic diamonds have the same hardness and durability as natural diamonds, and when cut into gems, they have the same brightness and fire. By controlling the introduced impurities, the optical properties can be changed in a wide range. For example, the crystal can be made close to colorless by controlling the remaining nitrogen level of the gas in the growth chamber. Blue diamonds can be made by adding boron gas; while pink, yellow or other colors can be made using gas mixtures, such as high nitrogen concentration. A special advantage of the CVD diamond production process is that all crystals grown in a growth chamber have the same color and clarity, which is convenient for grading and matching. Through continuous growth and synthesis, the color can be accurately repeated to ensure the reproducibility of color, clarity and size, while also ensuring the supply of high-quality synthetic diamonds for the gem industry. In addition, the controllability of size and clarity allows synthetic diamonds to have a wider range of use than natural diamonds, for use in new fields such as optics, medical equipment, electronic equipment, and other applications to be determined.

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.
