Diamond
Shapes
The most common diamond
shapes are round, emerald, princess, radiant,
oval, pear, marquise and heart. Because round
cut diamonds are the only shape that can achieve
an ideal cut, they are the most brilliant of the
diamond shapes. Fancy shaped diamonds adhere to
different proportion guidelines and thus refract
light in different ways.
Marquise Cut Diamond
The Marquise Cut takes its name from a legend
relating to the Marquise of Pompadour. According
to the legend, the Sun King desired a stone to
be polished into the shape of the mouth of the
Marquise. It is generally agreed that a length-to-width
ratio between 1.75:1 to 2:1 is most pleasing.
As with other fancy shapes, the consumer's individual
taste constitutes an element of the evaluation
as well. The typical marquise diamond contains
56 facets.
Princess Cut Diamond
The Princess Cut Diamond is a brilliant style
shape with sharp, uncut corners. It is typically
cut square rather as a rectangle. Brilliant style
refers to vertical direction crown and pavilion
facets instead of step style horizontal facets.
A princess Cut Diamond generally has 76 facets,
giving it more brilliance and fire than the round
brilliant. The Princess Cut diamond is fast becoming
one of the most popular cuts in the United States
Radiant Cut Diamond
The Radiant Cut Diamond is a straight-edged rectangular
or square stone with cut corners. The radiant
cut diamond has 62-70 facets. Radiant diamonds
are principally used for important center stones
primarily for rings but also for pendant. They
are rarely used for earrings or as side stones
because they are hard to calibrate and match.
To get matched pairs you may have to sort through
a hundred stones are re-cut to calibrate.
Emerald Cut Diamonds
An emerald cut diamond shape is usually rectangular.
The flat planes of the outside edges allow for
a variety of side stones shapes. Typical pairings
would be two or three side baguettes, two half-moons,
and other smaller emeralds, but not trillions
,as their sparkle makes the center emerald cut
look flat. The length-to-width ratio should be
between 1.5:1 to 1.75:1.
Pear Shaped Diamond
The pear shaped brilliant diamond is based upon
the traditional configuration of the round brilliant
diamond. More than other fancy shapes, length-to-width
ratio is a matter of taste when it comes to pear
shaped diamonds. Because pears may be used for
engagement rings, suites in necklaces, dangles
in earrings, and integral parts of custom designs,
a wide variety of shapes is considered desirable.
The typical pear shaped diamond will contain 58
facets.
Oval Cut Diamond
The oval cut diamond is based upon the traditional
configuration of the round brilliant diamond and
that's why its technical name is oval modified
brilliant diamond. The oval was invented by Lazare
Kaplan in the early 1960s. A length-to-width ratio
of 1.5:1 is almost universally considered a pleasing
shape for oval diamonds, with any variation beyond
1.4:1 or 1.6:1 beginning to be noticeable and
become an aesthetic issue. However as with all
fancies, a certain degree of individual taste
is always factored into the desirability of a
particular diamond's shape. Fifty-six facets are
typical for oval brilliant diamonds. Over the
last year or two ovals have become very popular
as center diamonds for engagement rings
