1.5 Carat To 2.0 Carat White Shade VS SI Purity HPHT Rough Diamond
For Making Def Color Lab Grown Loose Diamonds
Lab Grown Rough Diamonds Description
Diamond grown in laboratory is usually produced by chemical vapor
deposition (CVD) or high pressure high temperature (HPHT).
High purity high temperature heat treatment (HPHT), which has been
used since 1950s, places a pure solid carbon source under high
pressure and high temperature. In the presence of catalyst, the
carbon heated under pressure crystallizes into diamond. HPHT is
sometimes used to improve the color of mined or laboratory grown
diamonds.
Laboratory grown diamonds are man-made, like diamonds crystals.The
The manufacturing process work replicates the pressure and
temperature of the natural diamond production environment. By
adding a catalyst to the carbon and placing the mixture in a
high-voltage battery, the formation process is initiated by a
forced chemical reaction. The mixture was then cooled and washed
with acid to produce laboratory grown diamonds.
The quality of diamonds produced in the laboratory can range from
lower than natural diamonds to higher than natural diamonds,
depending on the technology and individual manufacturing processes.

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 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.
