The cutting process is the most important stage that reveals the sparkle, fire, and spark of the diamond. Special angle and dimension parameters are applied during cutting, paying particular attention to polishing. Poorly polished surfaces cannot reflect the light well and reveal the glow. Mistakes that may occur during cutting affect the brilliance of the diamond or reduce its reflection. You should choose diamonds with at least a “very good cut” degree to achieve the highest level of beauty, light, reflection, sparkle, contrast, and fire.
The best-cut diamond reflects light within itself, from one mirror-like surface to another. If the diamond is cut differently than the ideal, the light will not reflect outside the stone, it will disappear on the side surfaces or downwards. This decreases the brilliance and value of the diamond. There is a balance between the sparkle, fire, and spark of the best-cut diamond. The shimmer is the white light reflected from the diamond’s inner and outer surfaces. Light scattering, or more known as “fire”, is the colored sparkles coming from diamonds. Spark, on the other hand, is the sparkle you see as the diamond moves. It can also affect how the diamond’s cut size is perceived. Two diamonds with the same carat weight may appear to be of different sizes depending on the depth of their cut or the way they cut.
The advancing technology continues to offer new varieties, but the most common cut shapes are princess, oval, square, marquise, drop, radiant, emerald, and cushion cut. The cuts have developed over the years according to different tastes. The ‘Classic Old European’ section of the past, which emits large, wide, bright sparks, has been replaced by a highly sparkling, modern, round cut in accordance with today’s tastes.
How a Diamond Is Cut
When it comes to cutting a diamond, people usually think of the shape of the diamond. However, the shape expresses the appearance of the diamond (such as round cut diamond, heart cut diamond, drop cut diamond). Cut refers to the cutting rates, symmetry, and brightness of the diamond. Regardless of color, clarity, and carat, a well-cut diamond looks very sparkling and clear, while a poorly cut diamond looks dark and lifeless. Therefore, we can say that cutting is the most important factor in 4C. In addition to looking brighter, well-cut diamonds appear larger than diamonds of the same carat. In other words, the diameter of the “ideal” cut diamond is larger than the deep cut diamonds. As shallow-cut diamonds cannot reflect the incoming light back, they cannot show sufficient brightness. Therefore, ideal cut diamonds are more effective than others. In the international diamond certificates, diamond cutting standards are determined and classified as follows.
Excellent: If you want your diamond to be the best possible, it is the cut you prefer. It is the one that provides the highest price increase in diamond prices due to cutting.
Very Good: It is of near-perfect quality. It will be a wise choice because it is more affordable in price and high in quality.
Good: It is the segment that allows customers who do not want to compromise on quality and beauty to save costs perfectly.
Fair & Poor: It is a poorly rated segment that reflects a small amount of incoming light. It is a cut made to keep the carat weight high. It can be found in many jewelry stores. This diamond cut is not recommended if you want your diamond to shine.
It is more correct to choose diamonds with Very Good and Excellent cuts. Carat is seen as the most important factor in the eyes of diamond consumers in the world. However, this perception needs to be changed over time. Because if a 1-carat diamond has a poor cut, it is less flashy than a diamond with a 0.50-carat excellent cut and is similar to zircon stones. Therefore, cutting is seen as the most important factor by people who trade in diamonds. Ideally, cut diamonds are cut at ideal proportions and angles and show a perfect shine and symmetry. The most important feature of an ideally cut diamond is that it reflects light back from the table and cone and provides brightness since it has a perfect proportion.
Diamond is the name given to the processed form of the diamond mine found in nature in its raw form. The crystals in the raw diamond are shaved to obtain optimal cutting by observing natural particles. For example, it is designed to produce two diamonds from a rough diamond sometimes. One of them is an excellent cut and larger carat, the other is a diamond with poor or fair cut and lower in carat. Here, it is aimed to extract the maximum possible diamond from the rough diamond if it is necessary to think commercially.
While obtaining an excellent cut and a large carat diamond, the remaining part of the diamond is either shaved to obtain small (0.01-0.05 carat) diamonds or poor or fair cut diamonds are obtained. The main purpose here is to maximize profit. What you should pay attention to is that they do not have a poor or fair cut when buying diamonds. If it is not written on the certificate of the diamond, you can understand it by the glare and reflection of the light when exposed to light at different angles.
Diamond Cutting Techniques
The cut, which is the only feature of the diamond, which is the processed form of the raw diamond, created by human hands, is the most important feature in determining the beauty of the diamond. The dazzling sparkle of the diamond depends on the skill of the cut and the technology used. The better the cut, the brighter and more brilliant the diamond will be. Cutting is at the forefront of importance among the 4C features. Diamond owes its sparkle to its cut. When a good cut is held to the light, it reflects all the colors of the rainbow into your eyes like a spark. If you are buying certified diamond jewelry, make sure that the cutting class on the certificate is Very Good at worst. The cutting quality of the diamond is determined by the light reflection and breaking rates of the diamond. The light entering from one surface of the diamond cut in the right proportions with precision reflects from the other surface (in gemologists’ term from its table) and diffuses and spreads from the upper part called “crown”.
Diamond consists of three parts. Crown, belt, and cone. The section on the belt is called “Crown”. There are 33 facets in the crown section. Since the number of facets in the crown section is high, more reflection and brightness is observed in this section. Therefore, the crown part looks whiter than the general of the diamond. The “belt” portion can be natural, polished or faceted. Belt thickness affects the brilliance of the diamond. A thick-arched diamond looks dull, while a thin-arched diamond is vulnerable to pegging. The belt is an important part that keeps the diamond intact. Without the belt, the diamond could not be used in production.
The section under the belt is called the “cone”. There are 24 facets in the cone section. The cone part allows the light that enters the diamond to be reflected outside. The more the cone is cut at the right angle, the light entering the diamond is reflected and comes out of the crown. Thus, the optimum brilliance of the diamond is achieved. Sometimes a facet can be applied to the tip of the cone. With this facet, damage to the cone tip, which is the most sensitive part of the diamond, is prevented.
Although it is the hardest mine in the world, a diamond is vulnerable to impacts from certain directions and can break quickly. Diameter is the measure of the diamond’s belt from one end to the other. Depth is the height of the diamond from the table to the tip of the cone. A well-cut diamond consists of surfaces at right angles (facets) that best reflect its brilliance. However, the shape of the diamond and the cutting technique of the diamond are different issues. The shape of the diamond (such as round, princess, drop, emerald cut) varies according to taste.
Diamond cutting techniques are:
Ideal cut: The cut that allows almost all of the light entering the diamond to reflect from the surface is called the ideal cut. The most perfect of the diamond cutting techniques is the ideal cut. By keeping the table part of the diamond smaller than the good cut, it has been provided to have a better sparkle. In the meantime, the ideal cutting technique is also divided into cutting qualities such as perfect, very good, and good.
Good cut: It is a cutting technique close to the ideal cut. The diamond surface (table) is slightly wider than the ideal cut. It reflects almost all of the light entering. It is more affordable than the ideal cut.
Shallow cut: It is when the cut is not deep enough. It causes the light to escape from the cone and causes the diamond not to glow enough.
Deep cut: It is the cut formed by keeping the distance between the belt part of the diamond and the cone end. The deep cut causes some of the light to escape from the bottom of the diamond called the “cone”, causing it to not glow.
The Importance of Cut in Diamonds
Apart from the carat (0.20 carats, 0.50 carats) feature of the diamond, which we have paid attention to so far, the cut shape is also a feature that affects its quality. Moreover, the diamond cut shape is the only feature that affects its sparkle and touched by the human hand. The diamond mine, the raw form of diamond, matures under the ground for centuries, far from human beings. It gets almost all its features there. Until it comes out to the earth and collected by a master. In addition to the carat feature, which the diamond enthusiast first pays attention to, the cut is a feature that varies according to the skill of the master who will shape the diamond. Actually, the diamond cut feature is the biggest factor affecting the brilliance of the diamond.
Diamond is one of the most precious stones in the world. It is the processed form of the raw diamond. Its only feature created by human hands is its cut. The unique sparkle of the diamond is closely related to its cutting feature. The better the cut, the better the diamond will reflect light. The cut quality of the diamond determines the light reflection and refraction rates. The light entering from one surface of the diamond cut in the correct ratio is reflected from the other side and radiates from here and radiates from the upper part called ‘crown’ and scatters a visible glow. Diamond consists of three parts called Crown, Belt, and Cone. The part on the belt is called ‘crown’. There are 33 facets on the crown. Because of the high number of facets, brightness and reflection are very good in this area. Because of this, the crown of the diamond looks shinier.
The belt area can be natural, polished, or faceted. Belt thickness affects the gloss. A diamond with a thick belt looks more matte. Thin-belt diamonds, on the other hand, are not resistant to pegging. The belt is the area that keeps the diamond intact. Without the belt part, the diamond could not be used in production. The part under the arch is called ‘cone’. There are 24 facets in the cone area. It allows the light that enters the diamond to be reflected outside, the more the cone is cut at a right angle, the light reflects off the crown. There are also diamond cutting techniques. Cutting diamonds requires true craftsmanship. There are few good masters doing this work in the world today. Diamonds are also cut in different ways. These diamond cutting shapes are the biggest factor of the refractions, reflections, in short, the sparkle of the light.
Best Diamond Cut Types
- Round Cut
The oldest and most common is undoubtedly the round cut. It is also highly efficient and almost unlimited in terms of glow. It is the only cut used alone in all highly preferred jewelry. It is the most appropriate shape to be preferred in rings for a marriage proposal. Almost all of the solitaire rings have 57 facet round cuts. The reason why this shape is preferred is that it collects the light at an angle of 360 degrees and reflects it from the top. It is known as the cut that reflects the light most brilliantly. The round cut is the most popular cut since the diamond was discovered. In 1919 Marcel Tolkowsky developed the proportions that would form the basis of modern circular cutting. Today, the round cut is the only cut with the most perfect proportions. Three-quarters of all diamonds cut in the world consist of round cuts.
Again, it is among the most preferred and its shine is close to the round cut. If you are looking for both a round cut sparkle and a fancy cut, the oval cut will be the right choice for you. In addition to showing the little fingers long and elegant, solitaire rings can be preferred to add color to your jewelry with its shine in perfect harmony with other stones. The oval diamond has very similar features to the round cut diamond, except that it is elliptical. Its oval cut was developed by Lazare Kaplan in the 1960s. The oval cut diamond gives the appearance of larger size compared to the round diamond of the same weight. To find the oval shape you want, examine the length-to-width ratio on each diamond’s detailed page. This will determine what the diamond will look like when viewed from above. You can see the length-width ratios of oval cut diamonds that look beautiful when viewed from below.
Due to its shape, it makes the finger appear thinner and longer; It makes the diamond look bigger. This cut, which is symmetrical from one end of the diamond to the other, makes the fingers appear longer in solitaires. It is compatible with different cut stones. The typical marquise cut looks like a round cut with elongated ends. Legend has it that the name of this cut comes from the title of Marquise de Pompadour because King Luis 15 of France requested a special cut diamond that resembles the smile of the marquise. Consisting of 56 facets, this striking cut is ideal for ring models. The marquise cut makes the diamond look bigger and at the same time gives the perfect shine and sparkle of its round cut.
While the marquise cut maximizes the carat weight, it makes the stone look bigger than it is. This brilliant-cut looks beautiful when combined with round and drop-cut stones as side stones. The length of the Marquise makes the fingers look longer and thinner. To find the marquise shape you want, examine the length-to-width ratio on each diamond’s detailed page. This will determine what the diamond will look like when viewed from above.
The pear cut, which is frequently used in other models rather than rings, is different and fascinating with its splendor. It is highly preferred in earrings and necklaces. It is also preferred in solitaire rings. It makes the fingers look thin and elegant, and it is difficult to diversify it with other cuts. The pear cut is a variation on the traditional round cut. Pear-cut diamond has very good proportions and brilliance, it is the ideal cut for pendant or earring models. It can be cut to be thinner or wider. To understand what the diamond looks like when viewed from above, look at the length-to-width ratio on the detailed page of each diamond. For the most traditional drop-shaped diamonds, look for length-to-width ratios between 1.45 and 1.75.
- Heart Cut
The heart figure representing love is also included in the diamond cut. In terms of shape, it turns your diamond jewelry into a special design. The heart cut, which is a romantic cut, is called the representative of love and loyalty. It is frequently used in earrings and necklaces and rarely preferred in solitaires. The heart-shaped diamond is the most attractive of all the fancy cuts. The basis of the heart cut is based on the round cut. It is very important to find a heart diamond with a beautiful and distinctive outline. The tops of the heart form should not be pointed, but plump and clearly defined. Experienced cutting techniques are required to capture the pleasant and obvious heart silhouette.
When choosing the color grade for the heart-cut diamond, it should be taken into account that the color can be seen slightly from the corners, while the price of a heart-cut diamond in the color J is affordable. To find the heart shape you want, examine the length-to-width ratio on each diamond’s detailed page. This will determine what the diamond will look like when viewed from above. You can see the length-to-width ratio of the beautiful heart-cut diamonds when viewed from below. For a more traditional heart-shaped diamond, make sure that the length-to-width ratio is between 0.90 and 1.10.
The emerald cut, which takes its place among the fancy cuts, can be made in two ways, square and rectangular. However, the quality of the stone (color and clarity) is very important in this section. Because it is a cut that emphasizes the features of the diamond stone. It is the choice of those who like less shine. This cut called stepped, is the most preferred cut since ancient times. It is especially preferred in necklaces with its symmetry and inner light. It is insufficient alone in the rings. Since it reveals the natural colors and stains in the stone, it is recommended to be used in good clarity and less colored stones. This cut shape, which is mostly included in fancy cuts, is rectangular and square. The most important feature of this cut is that it clearly shows all the flaws in the stone. If an emerald cut ring is to be chosen, it is useful to pay attention to the color and clarity classes of the stone.
The princess cut, which ranks second after the round cut in terms of preference, has a very intense shine due to the high number of facets. It has taken its rightful place among the preferences with its modern appearance. Especially after the solitaire round cut diamond, the most preferred cut is the princess cut. It is called a princess cut solitaire because it is a solitaire cut that is square-like in shape and has a pointed solitaire. It is the symbol of nobility. It is the most preferred model after round cut in the world. The princess cut combines the look of a rectangular shape and the shine of a round cut. The number of facets of the princess cut can range from 49 to 78, but usually 78 for more intense shine. This is a relatively new cut, but it’s becoming increasingly popular thanks to its features that combine modern looks and gorgeous shine.
When choosing the color grade for a princess cut diamond, it should also be taken into account that the color can be seen slightly from the corners, for example, while a J-color princess cut diamond is affordable. Princess cut diamonds can be varied according to how square or rectangular their shape is. To find the size of the princess-cut diamond you want, you should examine the length-width ratio of each diamond on the detailed product detail page. This will determine what the diamond will look like when viewed from above. You can see the length-to-width ratios of princess cut diamonds that look beautiful when viewed from below. For those who prefer a square shape, the ratio should be between 1 and 1.05. If you prefer a more rectangular shape, you can look for length-to-width ratios greater than 1.10.
- Asscher Cut
This cut, made by Joseph Asscher (1902) on behalf of the Asscher company, was also realized as the first patented diamond cut. It was introduced to the world by brothers Edward and Joop Asscher in 2001 and is a very special cut. It is possible to find international certificates such as HRD and GIA. Because of the shape of the cut, the diamond gathers the focus right in the middle of the stone. Another interesting feature is the Royal Asscher logo, which is laser engraved on the product. That’s why the original Asscher cut is only available in antique shops. The 74 facets octagonal stepped cut has the feature of drawing eyes towards the center of the stone with its deeper cone and higher crown.
The original Asscher cut consists of 58 facets and can still be found in antique jewelry stores and auctions. If you choose SI clarity, check out the clarity section on the diamond certificate because this shape highlights the clarity of the diamond. When choosing the color grade for Asscher cut diamond, it should be taken into account that the color can be seen slightly from the corners, for example, while the price of a J-color princess diamond is affordable.
