Lab Grown Colored Diamonds Description
Lab
grown
diamonds,
also
known
as
lab
created
diamonds
or
synthetic
diamonds,
are
diamonds
produced
in
a
controlled
laboratory
environment.
The
diamonds
cultivated
in
the
laboratory
have
the
same
physical,
optical
and
chemical
properties
as
those
mined
by
the
earth.
Laboratory
diamonds
have
the
same
crystal
structure
of
carbon
atoms
as
natural
diamonds,
which
makes
them
have
the
same
superior
hardness
and
spectacular
beauty.
The
only
difference
between
laboratory
diamonds
and
mined
diamonds
is
how
they
are
made.
The
diamonds
mined
are
formed
in
the
earth's
crust,
while
the
diamonds
made
in
the
laboratory
are
made
in
the
laboratory.
There
are
two
methods
of
diamond
growth
in
laboratory:
chemical
vapor
deposition
(CVD)
and
high
pressure
high
temperature
(HPHT).
In
the
HPHT
method,
diamond
seeds
(diamond
fragments)
are
placed
under
extremely
high
pressure
and
temperature,
similar
to
the
way
diamonds
grow
on
the
ground.
The
diamond
seeds
are
put
into
the
bulk
carbon
and
placed
under
these
conditions.
The
carbon
melts
and
combines
with
the
diamond
seeds
to
form
diamond
crystals
after
cooling.
In
CVD,
they
take
a
diamond
seed
(usually
HPHT
diamond)
and
place
it
in
a
chamber.
They
filled
the
chamber
with
carbon
gas,
which
ionized
into
a
plasma
like
substance,
breaking
down
the
bonded
molecules.
The
carbon
from
these
leaves
forms
around
the
seeds
and
begins
to
crystallize.

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 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.
