The diamond cut is the way the raw diamond
is shaped and polished, how deep is the raw
diamond cut and how the facets are arranged.
Various
cuts of diamonds
are available and many of them
patented. Even diamonds with a similar shape can vary how the facet are
cut and arranged. One example are Asscher
and Princess diamonds, they are
square shaped diamonds but with a different facet
arrangements.
How the
crystal molecules of the diamond are
arranged will determine the shape and
cutting of the diamond. If the molecules
are arranged in an octahedron fashion, it
will be cut as a round diamond. Often, two
round brilliants
can be cut from the same original crystal.
If the crystal molecules are arranged in a
macer configuration, the diamond is cut as
marquise or oval diamond.
There are
several different types of diamond cuttings.
Emerald shaped diamond have a rectangle cut. If the diamond is
not clear enough, an emerald cutting can
cause the diamond to appear cloudy. In
comparing to the emerald cutting, another
similar diamond is the Asscher diamond. It
is a square cutting and looks like a spider
web when viewed from above.
Diamond cut
like pear-shaped or tear-shaped is
self-explanatory. This diamond is a
perfect oval that's wider at one end and
curves to a point at the other end. Another
different cutting is the marquise cut, which
can maximize the
weight of a stone with a flatter cut, yet the diamond is highly
faceted. The marquise diamond comes in a
variety of length-to-width ratios.
Many stones have rounded or cut-off
corners because a diamond can chip or
scratch when crashed
against something.
How diamonds are cut
is something special. |

The modern round cut
brilliant stone has
58 facets, or 57 if
the tiny bottom
facet, the culet, is
omitted. A unique
exception is the
Princess cut, which
is a square diamond
with pointed
corners. |

When people think
about diamond cut
they usually think
of the different
kinds of diamond
shapes they've seen
with diamond
jewelry, the
princess cut, the
round brilliant cut
and so on. But
diamond cut refers
to other parameter,
usually how well a
diamond cutter has
done his job to
achieve maximum
carat size and
brilliance, or the
millions of
glittering sparkles
you can see when you
turn your diamond in
the light. A diamond
is the
right anniversary
gift in
any case.
Poorly cut
diamonds will
often sell at a
cheaper rate than
the better cut.
Interestingly most
of diamonds aren't
cut for optimum
brilliance. There
are four factors
involved in the
diamond cut,
proportion, finish,
symmetry and polish
The proportion of
the diamond cut
has to do with the
table percentage
relative to the
depth percentage.
The table is the
flat surface on the
top of each kind of
diamond cut, while
the depth has to do
with the width of
the diamond from top
to bottom. A
excellent table to
depth ratio will
allow all light
coming into the
diamond to be
reflected back
through the surface. |

The symmetry of a
cut diamond is
how good the facets
of a diamond match
up. If the facets
don't match properly
then light entering
the diamond will
leak out the sides
and not be properly
reflected to the
surface,
classifications
of diamond cut
symmetry are the
same as for polish.
The polish of a
diamond refers
to how finally
polished the surface
is to make it very
reflective. Diamonds
are the hardest
materials on earth
and they must be
polished using
diamond grit, so the
process is time
consuming. The
grades for polish
range from Ideal to
Excellent, Very
good, Good, Poor and
Fair.
A diamond's
finish is made up of
the individual
diamonds polish and
symmetry. If a
diamond cut finish
is very good it
means polish and
symmetry of the
diamond are very
good.
Asscher Cut
Diamonds are
nearly identical to
emerald cut diamonds
and they are often
referred to as a
square emerald cut.

Joseph Asscher an eminent
diamond cutter, who cut
the 3,106 carat Cullinan
diamond, developed and
patented the Asscher cut
diamond in 1902.
This shape of diamond has
a square step cut with
an almost octagonal outline
and distinctive windmill
reflection plus wide cut
corners that are
characterized by concentric
square patterns. The Asscher
cut diamond has a small
table, a high crown, wide
step facets, a deep pavilion
and square culet.

An Asscher shape diamond
is cut with several
parallel steps, creating a
hall-of-mirrors effect when
looking deeply into the
stone. These steps create
more internal refraction and
diamond fire than typical
step cut stones, such as the
elongated emerald cut.
Because of its high crown
and small table, it has more
light and fire than an
emerald cut diamond.
Asscher cut diamonds
became very popular in Art
Deco jewelry and was a
forerunner of the emerald
cut. |

Because this cut
of diamond
produces
more fire than
you see in a typical
step cut diamond it
has become extremely
popular especially
with many Hollywood
stars and
celebrities.
Some of
the most beautiful
and stunning famous
diamonds in the
world are Asscher
and princess
cut diamonds - the
54.04ct D color
Porter Rhodes
diamond and the
flawless D color
Graff Asscher Cut
Diamond which weighs
21.46cts are both
great examples.
If you choose a
SI-clarity graded
Asscher cut diamond
be sure to view
the clarity plot on
the diamond
certificate, because
this shape can
highlight the
clarity of the
diamond. When
choosing this shape
diamond you also
should consider the

grade, for
colors below
J-color, in
various
fancy-shaped
diamonds the
color may be
slightly
visible in
its corners.
The optimum shape
for an Asscher cut
diamond has a
Length to Width
ratio of 1:1,
acceptable length to
width ratios can be
1.00 - 1.40: 1
depending on the
shape of the diamond
you desire, noting
that the greater
length to width
ratio the more
rectangular in shape
the diamond will
become.
A square
radiant cut diamond
is another excellent
square shape diamond
to be considered. |
