Diamond Shape

At Kama, we have an exceptional collection of traditional round diamonds along with the “fancy shaped diamonds”.



This shape is the most the popular of all. Our solitaire engagement rings studded with round brilliant diamonds are the most coveted ones. An ideally cut round brilliant diamond consists of 58 facets (including the culet is faceted) or 57 facets (if the culet is pointed). The top flat surface is one octagonal table, besides 16 kite-shaped facets, 40 triangular shaped facets and an optional small octagonal facet at the culet.

Present day diamond cutters employ progressive theories of light behaviour, and defined mathematical calculations to arrive at the finest fire and brilliance of a round diamond. While maintaining its fire and brilliance, round diamond is more adaptable to balancing cut, colour and clarity grades. Perhaps these are the factors that have nudged it to being a more popular cut.



This is probably the oldest known shape. The world famous Kohinoor diamond is a classic example of an oval shaped diamond. When worn, an oval shaped diamond creates the illusion of slimmer and longer fingers. Flawlessly symmetrical, the brilliance and sparkle of an Oval Cut diamond is alluring to those who may fancy a typical shape, yet not the usual round. Whether narrow or a broad one, the preference is purely personal!



The shape was named after the mistress of Louis XV of France, Marquise de Pompadour. The long, narrow shape of the diamond is said to resemble the shape of Marquise’s mouth. In this shape, the carat weight of a diamond is amplified, but its well-proportioned, elongated shape makes the diamond’s colour and clarity inclusions more conspicuous. Nonetheless, the Marquise cut best flatters the beauty of a diamond of a higher grade, when set as a solitaire. It is important to maintain symmetry in the cut, as the slightest difference can make the stone’s shape uneven.



This shape has been in use since the 1400’s. The oval and marquise cuts put together make a Pear shape. It resembles a tear drop. Symmetry is important in this shape, just like in the marquise shape, for an even balanced look. A traditional pear shaped diamond is obtained with a length to width ratio that ranges anywhere from 1.45 to 1.75. The pointedness of a pear shaped diamond creates an illusion of slimmer fingers, when worn.



Emerald Cut exhibits a pavilion that is cut with rectangular facets. Its concentric broad, and flat planes, are a replica of a short flight of stairs. A classic emerald hosts a ratio between 1.30 and 1.40, is more rectangular in shape, with the step cut facets. Its bevelled edges add enhance the appeal of the stone and make for a safe setting area for prongs.

In an emerald cut diamond, with its large table, all emphasis is laid on the clarity of the stone. It is this clarity grade that defines the price of an emerald cut diamond. Though the sparkle of an emerald cut diamond does not sparkle of a diamond that is cut with triangular and kite-shaped facets, it comprises this characteristic with its deep-seated clarity. In spite of it all, these diamonds are admired for their beauty and exactitude.



This cut is the next in popularity to the round brilliant cut that is used in solitaire engagement rings. Though a recent addition to the cutting styles, the Princess cut has gained popularity owing to the illusion of a larger diamond that it creates and of course, the flattering look that it adds to a lady’s delicately long fingers, especially when adorned as a solitaire.

A Princess Cut diamond is a quadrilateral with pointed corners. A diamond more square in shape has length to width ratio that is anywhere from 1 to 1.05. A more rectangular shape should give you a length to width that is greater than 1.10. Price of a princess shaped diamond is decided by its size and colour. A more clear princess diamond, in terms of its colour grade, will demand a higher price. This cut always requires a prong setting, to protect the pointed corners that may otherwise chip easily.



The Asscher cut style gets its name from its creator, Joseph Asscher, who invented this cut in the year 1902. Diamonds cut in this style are popular in art deco style jewellery. An Asscher cut diamond is square shaped with 72 wide step facets and sharp corners and bears resemblance to an octagon. Just like the emerald cut diamond its pavilion is deep with rectangular facets and a high crown but with a smaller table. However, unlike an emerald cut, the Asscher cut gives the diamond a brilliant shine and a clear appearance as good as a Round Brilliant cut diamond. Nonetheless, since the Asscher cut also highlights the stones inclusions, it is necessary to employ a diamond that is close to being flawless.



Invented in the mid-1700’s, this was the most common cut until the early 20th Century. The cushion cut has been designed to retain as much weight from the original crystal as possible. It is a combination of a square cut with rounded corners. Older cushion cut diamond, tends to display distinctive light patterns, than the contemporary ones and are thus considered to have high antiquarian value.



Inventor of the Radiant Cut, Henry Grossband, in 1977, decided to take the best from other diamond shapes, to capitalize on the colour refraction effect of the gem. With its 70 facets, the Radiant Cut is inspired by the stylish contour from an Emerald Cut, and the brilliance from a Round Cut. Yet, this cut does give the diamond a unique, tasteful, and brilliant look that sets it apart from the usual.



A representation of love, this diamond is delicately fashioned like that of a pear shape, with an addition of a cleft at the top. Balance and symmetry, of course, is important in this one as well. In shapes with obvious tips, such as the heart shaped diamond, grades of J-colour diamonds or lower, may reveal a tinge in the tip and rounded corners as well. The conventional length to width ratio of a typical heart shaped diamond, ranges between 0.90 and 1.10.



The triangular shape was introduced in the 1500’s, but brilliant versions of this cut became popular much later, in the 1960’s, with the invention of the Trillion Cut, a modern version. Yet another version of this cut, called the Trilliant was developed in 1978, which was a triangular version of the square shaped radiant cut. Triangular shaped diamonds are usually mixed cuts with sides that are either equally straight or slightly curved. This cut is considered rather fancy, but a proportionately faceted diamond may be brilliant enough to be used as a centre piece of jewellery.
