Diamond shape
Diamonds are cut in various shapes which maximize its diamond brilliance and give it a unique character. The cut of a diamond refers to its proportions, symmetry and precision while it has been cut and polished. The cut of a diamond affects how much light the diamond will emit, and this determines the degree to which it sparkles. These different types of light reflection are to as brilliance, fire (flashes of color), and scintillation (how light reflects with movement). There are many different types of cut or shapes of diamonds. The most popular are the Round brilliant cuts, followed by Princess cut diamonds. At Yadav Diamonds, you can choose f rom the 12 most popular diamond shapes, certified by GIA and IGI. There are classic twelve diamond shapes like round, princess, cushion, oval, emerald, pear, marquise, radiant, square radiant, aascher, heart, trillion that are most popularly used for jewelry and engagement rings. These have been cherished for centuries. Their beauty, sparkle have been passed on f rom one generation to another. Other Exotic shapes include Baguettes, Bullets, Half Moons, Trillion, Old Mine, Rose, even Horse head.
Learn more about the twelve popular cuts:

ROUND CUT DIAMOND:

Round Brilliant is the name given to a diamond that is cut with the most facets and angles for light return, and therefore the sparkle, are maximized. Polished with 58 facets its ideal proportions return a great amount of fire, brilliance and scintillation.

PRINCESS CUT DIAMOND:

This cut is particularly famous for its incredible shine despite its square cut and a shallow crown. The Princess Cut, technically known as a ‘Square Modified Brilliant Cut’, is a square version of the Round Brilliant Cut with numerous sparkling facets. It is the most environmentally f riendly as it uses up to 80% of the rough diamond and has the least amount of wastage. The princess cuts that are slightly rectangular tend to be lower in cost. This cut requires more weight to be directed toward the diamond's depth in order to maximize brilliance. Princess Cut diamonds are usually polished with 72 facets. Ideal square ratio ranges f rom 1.00 to 1.05. A princess cut should always be set for 4 prongs protecting its corners f rom chips.

CUSHION CUT DIAMOND:

Large facets of the cushion cut which augments the diamond's brilliance, largely compliment vintage-style engagement rings. Cushion diamonds have curved sides and either rounded or pointed corners with four or eight mains–kite-shaped facets between the girdle and the culet. If you prefer the square shape, look for a length-to-width ratio of 1.00 to 1.05. For a more rectangular shape, look for length-to-width ratios of greater than 1.18 - 1.20.

OVAL CUT DIAMOND:

A well proportionally oval cut diamond is beautiful on long slender fingers, gives great brilliance, fire and scintillation. Oval cut diamonds are generally polished with 56 facets. The Oval shape is for someone who likes a diamond with a larger surface area and is concerned with size. For the most traditional oval-cut diamonds, look for length-to-width ratios between 1.38 and 1.45.

EMERALD CUT DIAMOND:

The Emerald cut has step-like facets in a rectangular shape and has trimmed corners. Emerald cut has a larger, open table shape which is best suited for diamonds which have the superior clarity and color. The Emerald cut is typically polished with 44 facets. Emerald-cut diamonds can vary greatly in how rectangular they are. Generally, the optimum length-to- width ratio for an emerald cut diamond should be 1.38 -1.50.

ASSCHER CUT DIAMOND:

An emerald cut with a squared outline is an Asscher-cut diamond. An Asscher cut diamond is technically known as a ‘square emerald cut’. The Asscher cut is a unique diamond cut, with square shaped step-like facets with trimmed corners. Inspired by the table cuts of the renaissance, Joseph Asscher developed the Asscher cut in 1902. The ideal length to width ratio is between 1.00 and 1.05.

PEAR SHAPED CUT DIAMOND:

Pear shapes are typically polished with 58 facets, and the optimal length-to-width ratio is between 1.45 and 1.55.

MARQUISE SHAPED CUT DIAMOND:

The Marquise Cut was inspired by the fetching smile of the Marquise de Pompadour and commissioned by King Louis XIV, who wanted a diamond to match the smile. Similar to oval cut diamond, a proportionally marquise cut diamond is beautiful on long slender fingers, gives great brilliance, fire and scintillation. The Marquise has a slender shape characterised by two sharp points on either end. Marquise shapes are typically polished with 58 facets.The optimal ratio of length-to-width is 2:1, although a range between 1.85 and 2.05 is also acceptable.

RADIANT SHAPED CUT DIAMOND:

A Radiant cut diamond is a ‘cut-cornered, rectangular (or square) modified brilliant diamond’.Generally a square cut Radiant Shape’s length to width ratio is approximately 1.0 to 1.1:1. A rectangular shape has the ratio 1.18 to 1.25. Radiant Cut Diamonds have 70 facets in total, and the overall shape varies in their degree of rectangular shapes.

HEART SHAPED CUT DIAMOND:

This enchanting classic shape is the ultimate symbol of love. It is a lovingly modified brilliant cut with a lot of precision and skill. The standard number of facets polished in a Heart shape diamond is 59.The ideal length-to-width ratio is approximately 0.90 to 1.10.

TRILLION CUT DIAMONDS:

Trillion cut diamonds (also called “trilliant” or “trillian”) are triangle-shaped stones (often with rounded sides) were created for the first time in the Netherlands. They may be less popular as compared to round and cushion cut diamonds. They may be mostly used as accent stones around the center diamond on a piece of jewelry or as the main stone. Trillion cut stone will usually look larger as they are cut shallow and wide. If the size of your diamond is important to you, you should consider a trillion cut. If the Trillion Cut Diamonds are extremely shallow cut diamonds may have less brilliance despite their wide widths. This occurs because they will not have enough depth for the light to reflect and sparkle.

DIAMOND CUT SCALE:

The diamond cut scale has a category of excellent, very good and good. Excellent - The excellent category has the greatest sparkle. These diamonds emit is reflected internally, f rom one mirror- like facet to another, and dispersed evenly. This will perfectly balance the brilliant white light with intense flashes of fire (dispersion), which makes the diamond shine. Very Good – The cut in the diamond is not perfectly symmetrical, the light will mostly reflect through the top or crown of the diamond. This will still produce brilliance or a very high level of white light. Good – This diamond will appear slightly darker and low or almost no contrast at all. They will still reflect most of the light.

BUT HOW DOES A DIAMOND CUTTER DECIDE WHAT SHAPE TO CREATE?

The diamond cutter carefully observes the organic shapes and sizes of the rough diamonds. He then proceeds to make the best shape based with an objective to preserve and maximize the carat weight and value. It is an interesting fact that round cut diamonds result in the most wastage of rough diamond carat. Some of the other fancy shapes tend to have a longer, less uniform shape and depth which results in less wastage of the rough diamond. The diamond can be more valuable and less expensive if there is less wastage in the rough diamond while cutting its shape. Popularity and availability are the other factors that determine the price of the diamond. Diamond shapes are one of the most important factors of any ring. Jewelers use large diamond shapes so that they maximize the shine on the ring. This is now a popular trend because of the appearance of the ring, the life span of the diamond and the difference in the price. Different diamond shapes are more prone to damage than others. It is best to do some research on which shape would work best for your lifestyle.

DIAMOND CUT: HOW MUCH IT SPARKLES?

Diamonds are known for their intense sparkle caused by transmission of light. We often visualise the diamond’s cut as the shape (round, heart, oval, marquise, pear), but the diamond cut refers to the interaction of the facets of the diamond with the light. A lot of this depends on the precision and skill of the diamond cutter and how he will fashion a stone. A well cut stone will have perfectly symmetrical proportions and polish evaluated using the attributes of brilliance, fire, and scintillation. It's the cut that determines its overall proportions and its ability to reflect light.

WHICH DIAMOND CUT IS BEST?

Every diamond, no matter how large or small, has a set of unique characteristics that determine its value. A diamond is a diamond but the most appealing diamond will have the most sparkle. While a lot depends on your budget, the cut has the greatest influence on a diamond’s beauty and sparkle amongst the 4Cs (cut, color, clarity, carat).The most famous diamond cut and shape is the Round Brilliant. It contains 58 facets. The diamond cut grade strongly impacts its appearance and beauty. The more precise is the cut, the more sparkle f rom the light reflected by the facets. If a diamond is designed, cut, and finished properly, it will be so much more appealing and striking in its look and sparkle. It’s the most important of the 4Cs because it directly affects the sparkle. Only GIA has established parameters for analysing the round brilliant cut diamonds the shape that dominates the majority of diamond jewelry. GIA will calculate the proportions of diamond facets that influence the diamond’s face-up appearance. A diamond is evaluated on its ability to reflect and ref ract light in all directions. Experts study and analyze the proportions of the diamond to determine how successfully a diamond interacts with light for striking visual effects such as: Brightness or Brilliance : Internal and external white light reflected f rom a diamond. The interplay of light happens when light enters through the table or top of the diamond it will break into a rainbow of spectral colors, and is reflected back and forth within the interior of the gem while it bounces off in its mirror-like facets. Light exits through the table, recombining as white light. Fire or Dispersion: This refers to the scattering of white light into a rainbow’s spectrum of colors. When the light exits the table of the diamond, it stays separated or dispersed and reaches the eye in flashes of color. Scintillation: The intensity of the sparkle and the pattern created by the interplay of light and dark areas caused by reflections within the diamond. Scintillation is the play of light you see with movement of the diamond, demonstrated by sparkling on the diamond's surface. Experts will also consider the weight relative to the diamond’s diameter, the thickness of the girdle, the design and craftsmanship of the diamond, the facets proportions and symmetry and polish.

DIAMOND CUT GRADE OR SCALE:

The Characteristics Of A Well-Cut Diamond Are Superior Brilliance, Fire, And Scintillation. At Yadav Diamonds, we offer the following type of grade and cuts. At Yadav diamonds, we provide GIA certified natural diamonds. Excellent: These very rare diamonds belong to the top category.This rare cut represents roughly the top 10% of diamond cut quality. It has perfect proportion and symmetry which means it will have an even pattern of bright areas and dark areas. It reflects most of the light that enters the diamond. Very Good: This diamond grade is determined by brightness, scintillation, weight ratio and polish. It will have slightly increased darkness in the pavilion mains. This cut represents roughly the top 20% of diamond cut quality. This will still produce brilliance or very high level of white light at a lower price. Good: This cut represents roughly the top 30% of diamond cut quality. This diamond will reflect most light that enters. The cut of this diamond will optimize the size without sacrificing quality or beauty. Different types of Diamond Cuts: Ideal-Cut Diamonds: This premier cut style is well-proportioned and carefully angled to achieve a luminous appearance. If you’re buying a round diamond, simply select the “Excellent” cut diamonds (if graded by GIA) or “Ideal” cut diamonds (if graded by AGS) Deep Cut Diamonds: A diamond whose cut is too deep will look smaller than diamonds of similar carat weight. Shallow-Cut Diamonds: A shallow cut diamond allows light to escape f rom its sides instead of reflecting off its top.

WHAT IS A BRILLIANT CUT DIAMOND OR IDEAL CUT DIAMOND?

The most popular diamond shape for an engagement ring is the round brilliant cut diamond. The diamond was created after more than six centuries and multiple craftsmen f rom various generations. This resulted in a dramatic transformation of the diamond cutting process throughout the years. But what exactly is the brilliant cut diamond and why is it considered to be the ideal cut? Before 1939 diamonds had no universal grading system to determine the quality and value of the stone until GIA (Gemological Institute of America) established the 4C’s: Colour, Clarity, Cut and Carat Weight. Nature influences the colour, clarity and carat weight; the cut of the diamond is in the hands of a master craftsman. Therefore, the cut of the diamond is the only characteristic that is not determined when a diamond is formed.

THE ROUND BRILLIANT CUT DIAMOND

Diamonds were being polished and cut, even before they were discovered in the town of Kimberly in South Af rica. This radical discovery modified the world’s conception of the diamonds. The annual world diamond production increased by more than tenfold in the following 10 year. An extremely rare material was now within reach of wealthy Western society. The diamonds have been cut in various styles and looked significantly different to the brilliant cut diamond that we see today. Over the years the anatomy of a diamond has changed; each cutting style was one step closer to achieving the perfect cut. Table facets have become larger and lower half facets and star facets became longer. The culet of the diamond also appears smaller or almost non existent than before. The new cutting techniques were designed to make sure the maximum fire, scintillation and brilliance of the diamond is achieved.

A DIAMOND OF IDEAL PROPORTIONS

In 1919 a Belgian-born gemologist and mathematician named Marcel Tolkowsky established the best way to design, cut and polish the ideal diamond. He spent years determining the perfect symmetry and proportion for a diamond to reach its full potential. According to Marcel, a diamond is simply a system of mirrors and windows. The table of the stone was therefore mathematically designed to capture as much light as possible.
