HPHT Lab Grown Diamonds Description
Lab grown diamonds, as the name suggests, are synthetic diamonds
produced in laboratory. It's the only thing that's different from
their naturally occurring counterparts. Managed under strict
guidelines and a highly controlled pressure environment, authorized
creators replicate the exact composition of natural diamonds. Since
the core of diamonds is carbon, the diamonds made in the laboratory
have exactly the same chemical and physical properties, and there
is no monopoly regulation in the mining industry, so they are
cost-effective for consumers.
Lab grown diamonds are manufactured by advanced processes such as
high pressure high temperature (HPHT) and chemical vapor deposition
(CVD). When using the HPHT creation method, a small diamond seed is
placed in a pure carbon form. The seeds are then exposed to
temperatures above 1500 degrees Celsius and pressure of about 1.5
million pounds per square inch. The fusion of the two components
forms pure carbon diamond. When CVD is used, the process is
slightly different. A diamond seed is placed in a heated sealed
chamber and exposed to a carbon rich gas. High temperatures of 800
degrees Celsius combine with the gas, causing the carbon to
crystallize and form diamonds. These processes are merely
replications of the same environment in the earth's core.

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.
