HPHT Diamond Lab Created Rough Diamond Description
What is CVD/HPHT Lab Grown Diamonds?
CVD is an acronym for chemical vapour deposition and HPHT is an
acronym of High Pressure High Temperature. This means that a
material is deposited from a gas onto a substrate and that chemical
reactions are involved.
What is difference between CVD & mined diamond?
The only difference between CVD Diamonds and mined diamonds is the
point of origin.
Mined diamonds take millions of years to grow under the earth,
whereas CVD Diamonds are a high technology product which grows in a
matter of weeks. Since it is created in laboratory it comes without
flaws and is by far of better quality. Cannot predict the quality
standards, a complete flawless natural diamond is very very rare
and highly expensive.
What is the Eco-Friendly and Conflict Free Lab Grown Diamonds?
Lab Grown Diamonds grow above the earth in a diamond lab and unlike
mined diamonds; there is no excavation and mining hence keeping
nature and natural resources intact. This contributes in green
environments.

HPHT Diamond Lab Created Rough Diamond 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.
