HPHT Lab Grown Diamonds Description
Lab diamonds, 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 synthetic diamonds grow from the tiny carbon seeds of existing
diamonds. Advanced technology 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 synthetic diamonds 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.
Synthetic Diamonds 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.

HPHT Lab Grown Diamonds Introduction
Natural diamonds are created by nature and are the result of high
temperature and pressure formed over billions of years. The 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 Lab Grown Diamonds and natural
diamonds?
There is no obvious difference between the 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.
