Lab Grown Rough Diamonds Description
The diamonds made in the laboratory, also known as engineering or
cultured diamonds, grow in a highly controlled laboratory
environment. With advanced technology, they reproduce the natural
conditions for the formation of diamonds under the mantle and
crust. These synthetic diamonds are made up of actual carbon atoms,
which are arranged in the unique crystal structure of diamonds.
Because they are made of the same material as natural diamonds,
they have the same optical and chemical properties.
The diamonds in our lab grow from the tiny carbon seeds of existing
diamonds. Advanced technology - either extreme pressure and heat or
a special deposition process - mimics the natural methods of
diamond formation. Laboratory grown fancy colored diamonds are
formed when a small amount of specific trace elements are present
in the diamond growth stage, just like in nature. In white and
colored laboratory diamonds, the exact composition of trace
elements may be different from that of natural diamonds. Laboratory
diamonds can only be distinguished from natural diamonds by special
equipment, which can detect trace elements and subtle differences
in crystal growth.
The diamonds produced in our laboratory can now be easily bought in
all kinds of colorless diamonds. Cultured diamonds are also
available in fancy colors and are considered to be very rare in
nature, including the popular colorful Fancy Yellow. Compared with
natural color diamond, the price of color diamond produced in
laboratory is relatively reasonable.
Diamonds manufactured in our laboratory exhibit the same physical,
chemical and optical properties as natural diamonds, and exhibit
the same flame, flicker and flash. With a jewelry magnifying glass,
it is almost impossible to distinguish man-made diamonds from
natural ones. Laboratory diamonds may exhibit different trace
elements than natural diamonds and do not affect the appearance of
diamonds. Only by testing with special equipment can laboratory
diamonds be distinguished from natural diamonds. Laboratory
produced diamonds available for purchase should always carry
gemstone certification to confirm that they are laboratory
produced.

Lab Grown Rough 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.
