Lab Grown Rough Diamonds Description
The diamond grown in the laboratory is a real diamond, but not a
natural diamond, which means that it has all the same physical
properties of natural diamonds, but it is not the related cost of
mining natural diamonds.
Laboratory diamonds are sometimes associated with cheap diamonds,
but they are not cheap at all. They are just more cost-effective
than mined diamonds with the same physical properties as mined
diamonds.
These stones are not created by the power of nature as they were
millions of years ago, but by works of art in which one can
participate. The diamonds were produced in industrial laboratories
under the guidance of talented chemists, gemologists and
technologists. Their creation process is close to nature, but much
faster.
Since the best method of making stone was invented in the 1970s,
the stone cultivated in the laboratory has been actively used. They
are used in precision engineering, electronics and, of course,
beauty and fashion. It is in the case of jewelry production that
the diamonds cultivated in the laboratory are really shocking. He
gradually removed the natural gems from the base, because the
difference was invisible to the inexperienced.

Lab Grown Rough Diamonds Introduction
HPHT is the abbreviation for high temperature and high pressure
treatment, and its purpose is to change or improve the natural body
color of certain types of diamonds to make them more valuable.
In the past, it was called Pegasus diamond and GE POL diamond. The
reason why it is called GE Diamond is because The technology
developed by GE in the United States is a new product exclusively
sold by POL, a subsidiary of Israel's LKI, in 1999.
HPHT technology is to process natural diamonds at high temperature
and high pressure to enhance the color grade of diamonds. In one
move, it can be upgraded to 4-6 levels. However, not every diamond
can be processed by this technology. It must have a J color or
higher, and be free of impurities and high-clarity quality. During
processing, the results cannot be predicted. In other words, it is
not certain what level it can be promoted to.
At the same time, diamonds treated with HPHT may deepen or change
in color to become a colored diamond.
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.
