Lab Created Melee Diamonds Description
Lab-grown diamonds are diamonds grown in the laboratory using
equipment that simulate the growth environment of natural diamonds.
Both lab grown diamonds and natural diamonds are real diamonds. The
main chemical components of lab grown diamonds and natural diamonds
are carbon.
Lab grown diamonds is usually produced by chemical vapor deposition
(CVD) or high pressure high temperature (HPHT) methods.
The gem-grade synthetic diamond produced by the CVD (chemical vapor
deposition) method is beautiful in appearance and has almost the
same properties as natural diamonds. Because of their high purity,
these CVD products belong to Type IIa, which constitutes only a
small portion of natural diamonds. Under the advanced detection
technology, any diamond sample using CVD growth method can be
clearly identified.
Colorless and almost colorless synthetic diamonds are usually type
IIa, while only 2% of natural diamonds are type IIa. Type IIa
diamonds are characterized by high purity, and they exhibit
transparency in certain parts of the ultraviolet and infrared
spectra.
A hydrogen-rich environment can cause defects, called vacancies,
because occasionally carbon atoms will leave the diamond crystal,
creating vacancies. The carbon vacancy next to the silicon atom can
form a silicon vacancy (Si-V) center, which is very rare in nature.
The carbon vacancy adjacent to the nitrogen atom can form a
nitrogen vacancy (N-V) center, which is very rare in nature. The
defects of these two vacancies can be detected by spectroscopic
measurements such as photoluminescence, ultraviolet irradiation and
light absorption. Since diamond has the characteristics of
layer-by-layer formation, and nitrogen is non-uniformly fused
between the layers, growth stripes can be observed.

Lab Created Melee 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.
