Diamonds are available in nearly a dozen different shapes. The round diamond is considered to be the only traditional shape; everything else is a “fancy shape.” Each diamond shape is distinct and they all have their own particular qualities which set them apart from one another. A diamond’s shape is the physical outline that forms the diamond. There are a preexisting number of diamond shapes available. Cut should never be confused with shape since shape has no bearing on the brilliance of a diamond and how well-cut it is.
The princess cut is frequently chosen for its abundance of brilliance and singular cut. Princess cuts are noted for their sharp corners and square shape. Dimensions may factor into your decision to go with one princess cut over another since this diamond shape can lean either rectangular or square. A length-to-width ratio of 1 to 1.05 will give you a princess cut that falls on the square side while length-to-width ratios above 1.10 will mean such diamonds are longer and, therefore, more rectangular.
The emerald cut is known for its unique rectangular faceting, giving it a noticeably striking and clear appearance. Unlike other shapes, emerald cuts have a large transparent table that gives you an unobstructed view of their face. As with other square or rectangular diamond shapes, the emerald cut can be found in a range of lengths. You should refer to the length-to-width ratio of the particular emerald cut you are interested in to make sure it meets your requirements. A length-to-width ratio of 1.30 to 1.40 will result in the standard emerald cut shape. Anything significantly greater will mean an elongated emerald cut. This cut, also known as a step-cut, was intended strictly for emeralds and is now frequently employed for square and rectangular diamonds as well.
The cushion cut is a token of longevity – it has been the diamond cut of choice for many for over 100 years! This cut is also sometimes referred to as “pillow-cut” because of its rounded corners. The optimized brilliance in cushion cuts is the result of the enlarged size of their facets. Cushion cuts are a very popular shape in fancy color diamonds – the cushion cut is an excellent choice to maximize color and bring out its depth and richness. As with other quadrilateral diamonds, cushion cuts are available in square and rectangular options. A 1.00 to 1.05 length-to-width ratio means the cushion cut is square while a length-to-width ratio over 1.15 will mean the cushion cut is more rectangular.
If you’re in the market for a stone that looks large, but isn’t necessarily so in carat weight, then a marquise diamond may be just what you’re looking for. This eye-shaped diamond is a brilliant cut that flatters your fingers, lending them a long and thin appearance. If you want a classic marquise-cut diamond, choose a length-to-width ratio of 1.75 to 2.25.
The trademark feature of a radiant cut is its cut corners. It is a rectangular shape though its length is variable. Fancy color diamonds frequently appear as radiant cuts as this shape is excellent at accentuating depth of color. A length-to-width ratio of 1 to 1.05 means you will have a square radiant cut while a ratio over 1.10 will mean the radiant cut falls on the rectangular side of the spectrum.
The Asscher Cut can be thought of as the emerald cut’s fraternal twin – there are similarities in characteristics that tie the two together but enough of a physical difference exists to make them distinct cuts. Asscher cut diamonds are essentially square emerald cuts. Both cuts share the same type of pavilion, which consists of rectangular facets. The large transparent table gives you a clear view of the face. For a perfectly square Asscher cut, look for one with a length-to-width ratio of 1.00 to 1.05.
The pear shape diamond looks like its namesake, the pointy-tipped, round-bottomed fruit. This brilliant cut diamond is also sometimes referred to as a teardrop. Similar to marquise and oval cuts, longer pear shapes can make your fingers look effortlessly thin. Pear shapes are quite common among fancy color diamonds as it maximizes color magnificently. For a classic pear shape, pick a length-to-width ratio of 1.45 to 1.75.
The unique and alluring shape of the oval cut complements those with long and lean fingers, much like the marquise cut. The oval cut skillfully magnifies the richness of color in fancy color diamonds. A length-to-width ratio of 1.33 to 1.66 will give you the classic oval cut shape
No diamond cut is more romantic than the heart shape. This is truly an unconventional but nonetheless gorgeous shape. If you want a classic heart shape, pick a length-to-width ratio between 0.90 and 1.10.
