HPHT Lab Grown Diamonds Description
Lab Grown Diamonds, also known as engineering or cultured diamonds,
are grown in a highly controlled laboratory environment using
advanced technology, which reproduces 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 lab grown 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. Fancy color lab diamonds sell at a
relatively reasonable price compared to their natural color diamond
counterparts.
The lab grown diamonds are grown from tiny carbon diamond seeds
that already exist. Advanced technology - either extreme pressure
and heat or a special deposition process called chemical vapor
deposition - mimics natural diamond formation methods. Some
laboratory diamonds grown by deposition may also undergo pressure
and heat treatment after growth. Laboratory grown fancy colored
diamonds are formed when a small amount of specific trace elements
are present in the growth stage of synthetic diamonds, 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.

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. Professionals will be able to discern subtle contrasts in
inclusions between lab grown and mined diamonds.
