CVD Lab Grown Diamonds Description
Colorless and almost colorless CVD synthetic diamonds are usually type IIa, while only 2% of natural diamonds are type IIa. Type IIa diamonds are characterized by high purity (under a low nitrogen environment), and they exhibit transparency in certain parts of the ultraviolet and infrared spectra. Numerous UV detection instruments on the market can initially detect whether it is a CVD synthetic diamond. Of course, other tests are needed to confirm whether the sample is a CVD-grown diamond or a natural diamond. If the diamond is not Type IIa, it is most likely a natural diamond.
Because of its manufacturing scale and continuous accumulation of production experience, the CVD growth method will produce gems more efficiently. Nonetheless, as time goes by and inflation increases, the cost of the following manufacturing factors will become more expensive. First of all, the cutting and polishing costs of CVD products are basically the same as those of natural diamonds, and highly skilled craftsmen are still required to create beautiful products. The second factor is that the electricity required to produce one carat of diamonds is not proportional to the number of seed crystals or the size of the growth chamber. Electricity is a major cost, and electricity prices are expected to continue to rise in the future, so there is little room for cost reduction. The third cost is to produce seeds. This is an important expense, and it is impossible to find a cheap substitute for diamond seed crystals.

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.
