SI1-SI2 DEF Quality 3.0 Carat To 5.0 Carat Hpht Uncut Raw Diamond
For Making Lab Grown Diamond
Lab Grown Rough Diamonds Description
Diamonds made in the laboratory are made in the laboratory. It
starts with a small chemical called a diamond seed. It's then
exposed to high temperatures, plus a carbon coating, all of which
are designed to help laboratory made diamonds crystallize as they
grow.
Diamonds grown in the laboratory have the same optical and chemical
composition as those created by the earth. The flash point is the
same - the central difference between them is their origin.
Lab produced diamonds allow you to maximize your budget, giving up
more than 30% of your size at the same cost, while Earth created
diamonds are works of incredible natural and traditional choice.
The diamonds grown in the laboratory have the same chemical
composition and crystal structure as those produced in the earth.
Synthetic diamonds (such as cubic zirconia) are made of different
materials than Earth created and laboratory grown diamonds, and
it's easy to distinguish between the two. The diamonds produced in
the lab are real deals - they can't be distinguished from the
diamonds created on earth, even with a professional loupe.

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.
