Diamonds
Lab Grown Certified Diamonds Description
Diamonds are made of pure carbon in the shape of a tetrahedron.
Diamonds are famous all over the world as luxury and precious
jewelry. However, it is also the hardest substance in nature, a
good heat conductor and an inert substance. These characteristics
mean that diamonds can play an important role in some industrial
applications, such as metal cutting, drilling, grinding, mining and
construction, as well as applications in high-pressure testing and
high-performance bearings.
For a long time, people believed that diamonds could only be
created under high pressure and high temperature conditions,
imitating the formation of natural diamonds. The use of this method
to make diamonds is now very common, mainly for the aforementioned
industrial applications. However, in the late 1980s, scientists
discovered how to use a method called chemical vapor deposition
(CVD) to grow diamonds.
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.

Lab Grown Certified 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.
