A excellent cut
bring life into the
stone via facets reflection
light, one of the most
popular is princess cut and Asscher
cut,
there are other
cuts such as cushion cut, emerald cut,
round cut, radiant cut, rose
cut, brilliant cut, marquise
cut and more. Some of the
best cuts are patented.
The stone is shaped, cut and
polished, is the way to
bring the dull raw stone to life; many
diamond cutting procedures
are even patented. How deep
raw diamond cutting is done, how
the facets are arranged and
so on is quite a scientific
process these days.
Even stones of the same
shape vary according how the
facet are cut and arranged.
A very good and exceptional
beautiful example is Asscher
cut and princess cut,
|
|
both are square-shaped
diamonds with different
facet arrangements, the most
popular engagement ring
shape are this two.
The arrangement of the
crystal molecules in the
diamond finally determine
the shape and cutting of the
diamond. If the molecules of
diamonds
are arranged in an octagonal
pattern, it will be cut as a
round diamond. Many times,
two round diamonds are cut
from the same original
crystal. If
the crystal molecules are
arranged in a macer
configuration, the diamond
is shaped as marquise or oval
diamond. |
Some cutting history
Although diamonds have been
used as gemstones for over
two thousand years the first
enhancements for optical
effects only started in
approximately 13 th.
Century, before only raw
stones were used with
cutting edges when they were
to sharp.
Since then processing of the
raw stones gradually
improved, considering that a
diamond is more or less the
hardest material on the
planet the question always
was which material should be
used to cut and polish.
It was started by polishing
the flat surfaces of the
natural octahedron cristal
this was the real first
attempt to polishing the
stones.
In about 14 th. Century this
was improved a bit and
stones got a larger flat
upper side and a smaller
lowers side. Since the end
of the 15 th. Century the
introduction of a abrasive
wheel brought a great
technical improvement and
facet were possible to
increase the optical
expression of the precious
stone. In the middle of the
16th Century the development
brought faceted stones with
polygonal plates. The four
side edges of the upper and
lower parts are sanded which
finally comes to an 18
facets stone. Some more
facets at the sides produced
already 34 surfaces and a
rounded outline.

It is said that this cut was
a suggestion by French
Cardinal Mazarin in 1650,
hence Mazarin cut. By the
end of the 17th Century a
Venetian grinder invented a
cut with 58 facets. This cut
was named Peruzzi cut after
the Italian who invented it,
this is already very close a
brilliant cut which resulted
in the first real good cut
and polishing. But it took
time until 1910 when the
technology was developed to
implement the first real
brilliant cut.

An emerald shaped
stone
is a rectangle cut
with
longer, flat facets. If the
diamond is not clear enough,
an emerald cutting can cause
diamonds to appear cloudy.
Comparing to the emerald
cutting, a somehow similar
shape is the Asscher cut and
princess cut. It is a
multiple square cutting and
looks like a
spider web with
straight lines when viewed
from above. |

The horizontal width is also known
as table

Princess cut diamond is the real stuff of a princess
This is a patented stone cutting. Princess cut diamonds are very attractive, especially when used in a ring and engagement rings, its the right stuff for a princess and which women dont want to be a princess?
When looking at this diamond cutting from above the shape looks like a square or rectangular with four 90 degree corners, looking at it from the side the shape of an inverted pyramid with four beveled sides.
Princess cut was created
in the late 1979 and appeared on the diamond market |
Princess cut diamond engagement ring looks a bit similar to

Princess cut diamond ring |
in the early 1982, the princess cut is very popular for diamond rings and engagement rings. Princess cut diamonds are also used for diamond necklace, diamond band and diamond bracelets, naturally also for diamond pendants.
The look of a princess cut diamond has a modern touch and the cut uses the stone in a more economical way than other diamond cutting.

Diamond cutting is a real art. Imaging to create this unique piece of a a fabulous princess cut diamond out of a semi transparent stone which looks like nothing before and afterwards all this glitter and fire of light.
A Diamond cut
was probably first performed on the Indian subcontinent by some creative people. European traveler to India got the basic idea from the Indians but it was not until around the sixteenth century that anything sophisticated was done probably because no effective material existed to to cut and polish the stone.
Early attempts to cut were called rose cuts because they somehow followed the pattern of a rose. That means triangular shaped facets cut in a pattern on the top of the diamond. The bottom of the diamond was left flat for mounting.
Only in the 20th century the diamond cutting technology started to be available reflecting light in various. In the 21st century computer modeling is often used to help determine the cut of a diamond. Modern diamond cutting is a symbiosis of art and science.
In a Diamond mine
they are just a simple shiny little rock.
First is the proportion
relative to the whole stone. How is the polishing and third the symmetry of the facets. This three parameter determine how the light is reflected out of the diamonds.
There's a certain international terminology used around diamonds. Its the table, crown, crown angle, girdle, pavilion, pavilion depth plus pavilion angle. The top most flat part is called the table. The largest diameter of the diamond is called the girdle. This top part of the diamond from the girdle up to the table is the crown and crown height. The crown angle means the depth of this part of the stone and the angle from the girdle up to the table.
The part of the stone not visible when you looking down is the pavilion, this is from the girdle down to the bottom of the diamond, the bottom of the diamond is usually pointed. The distance from the girdle down to this point is called the pavilion depth and the angle from the girdle edge to that point is the pavilion angle. The gem is finally graded as good,
very good, excellent. Another parameter important to a excellent cut is the symmetry, this is the shape, size and the proportions of the facets. |

Some other important diamond parameter are,
have all facets a consistent shape? Do the points of one facet align perfect with the next facet? Are the lines of the cuts straight or ? Are the facets flat? These more or less define the value of a modern cut diamond.
