Lab Grown Rough Diamonds Description
The best diamond made in the laboratory is type IIA, which is the
purest diamond at present. In fact, only 2% of natural diamonds on
earth are so pure. On the other hand, diamonds made in the
laboratory are made in a highly controlled and monitored,
pollution-free environment, so quality assurance is built-in.
Although all the diamonds planted in the laboratory are great, just
like the diamonds mined with clay, no two are the same. There are
differences in reflection, clarity and refraction of light, which
make the stone "shine", so the key is to find a stone that can
speak to you.
The best laboratory diamonds are cut, polished and graded in the
laboratory, and the laboratory has proven the diamonds mined.
Transparency should be the same as or better than the ground
diamonds mined, usually in the range of if to SI2. In addition to
reading the diamond certification, you also want to examine the
stone carefully and consider determining the quality of the 4 C:
color, cut, clarity and carat weight. The cutting and definition of
stone affect the brightness and luster of diamond by changing the
way that diamond refracts light. The quality of diamond color is
usually subjective. Because the saturation of hue can be
controlled, there may be many kinds of stone colors. The carat
weight of a diamond directly reflects its value, because it is an
expression of rarity. The diamond planted in the laboratory is
heavy and not as rare as the native diamond, but the carat weight
can be used to refer to the size of the stone, and its price is
natural.

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.
