CVD Lab Grown Diamond Plates Description
The chemical vapor deposition (CVD) method uses the carbon gas source (generally methane + hydrogen) as the raw material, through a certain amount of energy input (microwave, hot wire, DC, etc.), produces a plasma under a certain pressure, in which the carbon gas is decomposed, the hydrocarbon bond is broken, the carbon carbon bond in the diamond structure is formed, and the carbon carbon bond is continuously combined to make it "grow up", This method has the advantages of fast synthesis rate (higher than high temperature and high pressure method), high quality (impurities can be avoided) and easy control (different crystal planes and different kinds of diamonds can be made by adjusting the process parameters).
The methods of CVD are also divided according to the different ways of providing energy. The input energy in the form of microwave is called MPCVD; HFCVD is a method of heating the hot wire to provide energy by applying high pressure on both sides of the hot wire; Another is to apply DC voltage to the cathode and anode, and the gas will be ejected from the anode nozzle at high speed to form a plasma jet after being heated. The heating mode is dc-cvd in the form of jet. The most promising among the three is MPCVD method, which can produce diamond with high purity and good quality, and its performance is comparable to or even better than natural diamond.

CVD Lab Grown Diamond Plates 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.
