Square Shape VS Plus Clarity 6.0 Carat To 7.0 Carat CVD Lab Grown Diamonds For Cutting Round Cvd Diamonds
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.
