CVD Single Crystal Diamonds Description
CVD diamond is made at low pressure. The mixture of carbon containing gas and hydrogen is excited to decompose at high temperature and pressure lower than the standard atmospheric pressure to form active diamond carbon atoms, which are then deposited on the substrate to form polycrystalline diamond (or single or quasi single crystal diamond is deposited under controlled deposition conditions). Because CVD diamond does not contain any metal catalyst, its thermal stability is close to that of natural diamond.
The hardness, wear resistance, thermal conductivity and thermal stability of CVD diamond materials are much better than those of PCD materials, which can be comparable with single crystal diamond. Therefore, CVD diamond materials can achieve efficient processing of high hardness materials and difficult to machine materials, such as glass fiber reinforced plastics. It allows higher processing speed and shows longer service life. With the improvement of industrial processing technology and efficiency in the world, it will replace the widely used PCD blade material in a large range.
CVD diamond material has excellent surface finish and low friction coefficient after polishing, which can greatly reduce the cutting force and friction heat generated during cutting. It has excellent anti burr performance, and the machining finish is close to that of single crystal diamond tool.

CVD Single Crystal 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.
