CVD Rough Diamonds Description


Lab created diamonds can be made by HPHT and CVD methods.
What CVD stands for?
Chemical vapor deposition (CVD) is a process in which the carbon containing gas is dissociated and the carbon atoms are deposited on the substrate to form diamond films.
Diamond crystals grown by CVD are mostly plate-shaped, and occasionally small octahedral faces and diamond dodecahedral faces can be seen at the edge. The color of early CVD diamonds is dark brown or light brown, while recently discovered CVD diamonds have been proved to be colorless or nearly colorless after high temperature heat treatment. There are few inclusions in CVD diamonds, some of which are needle like and black irregular. However, it can not be used as a basis for distinguishing natural diamonds from HTHP synthetic diamonds. There is no metal inclusion in CVD diamond, so it is not magnetic.
Although the laboratory-grown rough diamonds are grown in the laboratory, they are composed of carbon atoms, have the same physical properties and chemical composition as natural diamonds, and have fewer impurities and higher purity than natural diamonds. And it's cheaper.

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.
