Description
Cultivation
of
diamonds,
Lab
created diamond
(Synthetic

business
name,
also
known
as
Laboratory
Grown
diamond.
Refers
to
in
the
laboratory
or
factory
through
a
certain
technology
and
process
to
manufacture
and
natural
diamond
appearance,
chemical
composition
and
crystal
structure
of
the
same
crystal.
A
national
standard
for
synthetic
diamonds
led
by
NGTC
is
being
developed.
An equiaxed crystal body consisting of carbon atoms formed wholly or partly by the growth of an iOL.
The
physical
properties,
chemical
composition
and
crystal
structure
are
basically
the
same
as
those
of
natural
diamond,

In
July
2018,
the
FEDERAL
Trade
Commission
(FTC)
changed
the
62-year-old
definition
of
a
diamond
to
recognize
a
lab-grown
diamond
as
a
diamond.
Diamond
synthesis
methods
include
chemical
vapor
deposition
(CVD)
and
high
temperature
and
pressure
(HTHP).

High
pressure
high
Temperature
method
(HPHT)
Growing
diamonds
requires
an
indispensable
element:
carbon
(C).
In
the
process
of
growing
HPHT
diamonds,
pure
carbon
powder
is
compressed
into
a
growth
capsule
and
then
placed
in
a
incubation
chamber
at
pressures
of
5-6
gpa
and
extremely
high
temperatures
(up
to
1300-1600°C)
day
in
and
day
out.
Eventually
the
carbon
atoms
join
together
to
form
a
diamond
crystal.
Many
large
diamonds
over
10
carats
can
be
produced
in
one
go
in
less
than
two
weeks.
