History of Diamond Cuts
Prior to the Middle Ages diamonds were worn rough, or cut and
polished only on the upper surface. They were used
to ornament temples, goblets, reliquaries and crowns. In 1458 Lodewyk (Louis) van Berquem of Brugge,
Belgium is credited with creating the first brilliant diamond Cut. Diamonds
then became popular as ornaments in jewelry and the different techniques
and styles of diamond cuts were gradually developed. Click one of the following

Step Cut Diamonds - Square, Oblong or Rectangle Shaped Diamonds
Many Square, Oblong
or rectangular diamonds are 'Step cut' or 'Table cut' which the cutting style is often used in Marquise, Emerald and Oval cut diamonds.
The facets on a 'Step cut' are cut in steps. The crown, pavilion,
and the table are all cut in rectangular facets. These diamonds are
bright, clear and shiny in appearance as its facets usually span the length or width of
the stone, the facets gradually decreasing as they approach the table.
Facets produce the sparkle
Facets are the smooth surface areas of a
stone which have been
cut, polished and positioned at different angles which allow light to
enter and reflect back from diamonds. The depth and width and the
uniformity of the facets control the brilliance and the durability of diamonds. The quality of the facets are the major
determining factor in enhancing the diamond's ability to sparkle or
reflect light and facets play a large part in the resulting brilliance of the
stone.

Fancy Cut Diamonds
Fancy cut diamonds
and other stones include the Emerald, Marquise, Heart, Oval, Pear and Princess.
Fancy
cuts are all ways of cutting diamonds or other stones to maximize the carat weight.
Rough diamonds which might only yield a half carat whereas in a Brilliant Cut
the same stone might yield another 50% if cut into one of the above shapes. Fancy cuts
allow the cutter to use the best attributes of rough diamonds and
eliminate inclusions and blemishes. Popular fancy cuts include the
"Baguette" (bread loaf), "Marquise" or "Navette" (little boat),
"Princess Cut" aka Square Brilliant Cut, "Heart", "Briolette" (a form of
Rose cut), Pear (teardrop), and the Trillion which is triangular in
shape.
Good Diamond Cuts and Common Problems
What constitutes
good diamond cuts? Good diamond cuts are effected by several different
elements:
-
The Width and Depth
of the stone have a large impact on a diamond's
brilliance
-
Shallow Cuts appear lifeless as the light travelling through
the stone is lost out of the bottom of the diamond
-
Diamonds which are cut too deep appear lifeless as the light
travelling through the stone is lost out of the sides of the diamond
-
Diamond Symmetry refers to the alignment of a diamond's facets which
should be cut to achieve the best play of light
-
Diamond Polish - the surface of the facets should be smoothly
polished to enable light to pass through them
-
A
misaligned, broken, chipped or missing culet is a common problem as
are misaligned or extra facets
Diamond Inclusions
and Clarity
Diamond Clarity is
one of the 4 C s of diamond grading (Cut, Color, Clarity and Carat
Weight) and is a measure of a diamond's blemishes and internal
flaws and impurities ( called inclusions ) which effect the brilliance
of a diamond and its sparkle because they interfere with the passage of
light travelling through the diamond. Diamonds are graded for clarity on
a scale ranging from flawless to imperfect. For detailed facts and
information about inclusions and the 4 C's please click one of the following
