CVD Lab Grown Diamonds Description
What is cultivating diamond?
The physical and chemical properties of cultivated diamonds are the
same as natural diamonds. With the progress of science and
technology, the purity and color of cultivated diamonds are getting
higher and higher, which can be used for jewelry.
At present, there are two main methods to produce lab grown
diamonds: HPHT and CVD methods.
Nowadays, the color of white lab grown rough diamonds can reach D-E
level and the clarity can reach vvs-si level.
Since diamonds can be cultivated artificially, can they be mixed
with natural diamonds?
In fact, there is no need to worry about this. By comparing the
crystal shape, internal growth characteristics, inclusion
characteristics, absorption spectrum, cathodoluminescence and other
aspects of the tested diamonds, lab grown diamonds can completely
be distinguished from natural diamonds. After all, natural diamonds
are formed in a relatively stable environment deep underground for
a long time. However, it only takes a few weeks or even days to
make lab grown diamonds. There are subtle differences in the growth
environment between the two, which can be distinguished by
professional detection methods.
Generally speaking, Lab Grown Diamonds grown in the laboratory are
almost no different from natural diamonds, and it is difficult to
distinguish them with scientific instruments. In essence, Lab Grown
Diamonds and natural diamonds are actually a kind of thing, but
they are produced in different ways.

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 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.
