Lab Grown 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.
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 (under a low nitrogen
environment), and they exhibit transparency in certain parts of the
ultraviolet and infrared spectra.
HTHP: Due to the use of metal catalysts in the HTHP method, some
metal will inevitably enter the crystal during the growth process,
so it is magnetic. If the cleanliness is poor, it has strong
magnetism. This probe cannot pass the latest drilling probes. HPHT
synthetic diamonds usually contain metal co-solvent inclusions,
which are black and opaque under transmitted light, and appear
metallic under reflected light.
CVD: Since CVD is a method of depositing and growing a diamond film
on a substrate (substrate), it is easy to see the layered structure
and water ripple-shaped growth pattern of CVD under a 10x
magnifying glass, which is easily distinguished from natural
diamond. CVD synthetic diamonds do not contain metal inclusions.
But they usually contain dark graphite inclusions or other mineral
inclusions, which are formed during their unique growth process.

Lab Grown 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.
