HPHT Lab Grown Diamonds Description
Many
people
refer
to
Lab
Grown
Diamonds
as
'fake'
diamonds,
but
this
is
not
accurate.
The
carbon
based
chemistry
of
Rough
Lab
Grown
Diamonds
means
that
they
are
actually
"real"
diamonds
-
unlike
cubic
zirconia
or
moissanite.
What
is
a
lab-grown
diamond?
Lab-grown
diamonds
after
polishing
and
cutting
are
no
different
from
natural
diamonds.Carbon
is
the
main
element
of
natural
and
laboratory-grown
diamonds.
The
HPHT
synthesis
method
is
a
more
traditional
diamond
cultivation
method
that
uses
molten
metal
alloys
such
as
iron
(Fe),
nickel
(Ni)
or
cobalt
(Co)
to
form
diamonds.
The
CVD
synthesis
method
is
a
relatively
new
method
of
cultivating
diamonds.
The
vacuum
chamber
is
filled
with
carbon-containing
gas.
A
carbon
plasma
is
formed
at
the
bottom
of
the
vacuum
chamber.
The
plasma
is
continuously
deposited
on
the
carbon
bottom
layer
at
the
bottom
of
the
pressure
chamber.
For
several
weeks,
the
resulting
flake
crystals
usually
have
black
rough
edges,
and
the
crystals
often
appear
brown,
but
they
can
be
removed
by
heat
treatment.
Many
people
have
similar
worries:
since
diamonds
can
be
created
in
lab,
can
they
be
mixed
with
natural
diamonds?
If
I
want
to
buy
natural
diamonds,
will
I
be
cheated
by
using
the
price
of
natural
diamonds
to
buy
lab
diamonds?
With
professional
equipment,
the
comparison
of
the
color,
crystal
shape
and
crystal
surface
characteristics,
internal
inclusion
characteristics,
absorption
spectrum
and
ultraviolet
fluorescence
characteristics
of
the
tested
diamonds
can
"completely
distinguish
the
artificially
cultivated
diamonds
from
the
natural
diamonds".
After
all,
natural
diamond
crystals
were
formed
billions
of
years
ago,
while
artificially
cultivated
diamonds
can
only
be
formed
in
a
few
days.
There
is
no
difference
between
the
two,
and
it
can
be
completely
distinguished
by
professional
testing
tools.

HPHT Lab Grown 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.
