Shape refers to the general outward appearance of the diamond. Round, emerald or pear is some of the shapes commonly found.
Cut refers to a diamond's reflective qualities, not the shape.
Diamond
cut is perhaps the most important of the four Cs, hence, it is
important to understand how this quality affects the properties and
values of a diamond. It makes a difference in how a diamond looks. A
good cut gives a diamond its brilliance, which is that brightness that
seems to come from the very heart of a diamond. The angles and finish
of any diamond are what determine its ability to handle light, which
leads to brilliance.
Most gemologists
agree that the best cut diamonds are those that follow a set of
formulae calculated to optimise brilliance. These formulae can be seen
in a diamonds’ proportions, most importantly how the depth compares to
the diameter, and how the diameter of the table compares to the
diameter of the diamond.
However, the variance in the proportions between an ideal cut and a poor cut can be difficult to discern by the casual observer.
Since
the cut is so important, several grading methods have been developed to
help consumers determine the cut of a particular diamond. They are;
Ideal
Premium
Very Good
Good
Fair
The Shape
The traditional round brilliant diamond, thought the most popular shape of all, is hardly the whole story.
Diamonds are natural crystals of verying size and shape formed in the earth over millions of years.By the diamond
cutter's art, these crystals are carved into gems of spectacular and whimsical beauty. A cutter's skill will produce a
diamonds of the greatest size with the fewest flaws and the most brilliance
Round Brilliant
Accounting for more than 75% of diamonds sold today, its 58 facet cut is
calibrated through a precise formula to achieve the maximum fire and
brilliance.
Oval
Popular among women with small hands or short fingers, this even, perfectly
symmetrical design gives a flattering illusion of length to the hand.
Marquise
Gorgeous when used as a solitaire or when enhanced by smaller diamonds.
Pear Shaped
A hybrid cut, combining the best of the oval and the marquise, it is
shaped to resemble a teardrop. It also complement s a hand with small
or average length fingers. Particular ideal for pendants or earrings.
Heart Shaped
The skill of the cutter determines the beauty of the cut. An even shape
and a well defined outline are important qualities to look out for.
Emerald Cut
Also known as a step cut because of its concentric broad, flat planes
resembling stair steps. Usually rectangular shape with cut corners, the
square shape with similar step cuts is called Asscher Cut
Inclusions and inferior colour are more pronounced in this cut, hence,
look for a diamond of higher clarity and colour.
Princess Cut
A relatively new cut, which is often square in shape with numerous
sparkling facets. Some called it a square modified brilliant. Flattering to a
hand with long fingers. Often set with triangular stones at its sides.
