Lab Grown Colored Diamonds Description
Synthetic
diamond
is
mainly
produced
by
high
pressure
and
high
temperature
(hPTP)
and
chemical
vapor
deposition
(CVD)
methods.
And
its
quality
is
similar
to
natural
diamond.
Artificial
diamonds
are
often
used
to
process
priceless
jewelry.
Over
the
past
decade,
laboratory-made
diamonds
have
received
widespread
attention
because
it
allows
for
new
applications
of
many
diamonds
that
have
previously
been
considered
too
difficult.
Artificial
rough
diamond
is
an
environmental
protection
product,
100%
of
which
is
free
of
conflict.
With
the
progress
of
human
science
and
technology,
scientists
moved
the
natural
diamond
growth
environment
into
the
laboratory,
simulated
the
whole
growth
environment
of
diamonds
with
high
pressure
and
high
temperature,
and
used
gravel
sized
diamonds
as
seeds
to
grow.
Diamonds
grown
in
the
laboratory
are
manufactured
by
advanced
processes
such
as
high
pressure
and
high
temperature
(hPTP)
and
chemical
vapor
deposition
(CVD).

Lab Grown Colored 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.
