Vs Si Purity 3.0ct - 5.0ct HPHT Rough Diamonds For 1 Carat Loose
HPHT Diamond Cutting
Lab grown HPHT/CVD diamond are manufactured, diamond-like
crystals.The manufacturing processes work to duplicate the pressure
and temperature of the natural diamond-producing environment. The
formation process is initiated by forcing a chemical reaction,
through adding a catalyst to carbon, and placing the mixture in
high-pressure cells. Then, the mixture is cooled and washed with
acid, which results in a synthetic HPHT diamond.
Quality of lab grwon HPHT/CVD diamonds can vary from inferior to
superior to the natural diamond, depending upon the technology and
individual manufacturing processes. The methods used in the
production of synthetic diamonds are high pressure high temperature
(HPHT) OR Chemical Deposition Method

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 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.
