HPHT Lab Made Uncut Rough White Lab Diamond Description
What is CVD HTHP diamond?
Lab Grown Diamond is also widely known as HTHP diamond or CVD
diamond after the two common production methods (referring to the
high-pressure high-temperature and chemical vapor deposition
crystal formation methods, respectively). Under HTHP method, purest
carbon is given the same environment into the lab so that it can
convert into the diamond and in CVD method, the atmosphere is
created which leads to atom by atom formation of diamond.
The difference between mined and lab-grown diamonds is
indistinguishable to the naked eye, only a trained gemologist using
specialized equipment can spot the difference. The price difference
between mined and lab-grown diamonds is in the range of 30-70%,
with lab-grown diamonds being cheaper and free from impurities.
It is a common misconception that lab grown diamonds are of
inferior quality, but with advanced technology, they are made of
even better quality than mined diamonds. There is also the
misplaced notion that diamonds are expensive due to polishing and
other processes. But as lab grown diamonds are made from scratch,
it is relatively cheaper. Due to the price difference as well as
the superior quality, lab-diamonds are being increasingly preferred
over mined diamonds.

HPHT Lab Made Uncut Rough White Lab 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.
