Diamond Shape Choosing Guide


When looking for a wedding or engagement ring, or a different kind of jewelry, and before shopping, you are left with various and long-term decisions to make. In the case of a diamond gem, although the choices made regarding clarity, carat, and color play an important role in choosing the right stone, the most important decision to be made is to choose the shape of the diamond that will be noticed at first sight. The diamond shape refers to the physical structure that forms the general appearance of a diamond and its geometric outline.

The diamond shape has the most noticeable contribution to the overall appearance of jewelry; some shapes have a more vintage look while others have a more modern feel and accordingly, there are different designs for every taste, from an oval cut with soft curves to an angular shape princess cut, and so choosing a diamond shape is essentially based on personal criteria. is the choice. The features that need to be considered after this selection are features such as size, clarity, and color that are more effective in the price. If you want to make a classic choice, you can choose the round cut, which has a symmetrical shape, a uniform facet structure, maximizes light, and is, therefore, the most preferred diamond shape. However, you may not want to choose a round cut just because it shines more, and as a result, you may consider other criteria in addition to the shape.



In addition to diamond shape, there is one criterion to evaluate diamonds. This is called the “diamond cut”. “Diamond cut” term refers guide of design is put use in the process of shaping a diamond. For instance, in the polishing process such as the “brilliant cut” is used a diamond cut guide. You should know that the “cut” term does not mean to diamond shape like round, princess, etc. In most general terms, it refers to the polish, proportion, and symmetry of a diamond.

About Diamond Shape

Diamonds differ in the way they are cut. In this case, the issue of how a diamond cutter knows which shape it will create may come to the fore. The first responsibility a diamond cutter must fulfill is to both maintain the carat weight of the diamond and maximize it. Since their shapes and sizes are unpredictable, during the processing of rough diamonds, the diamond cutter shape will form whichever value it maximizes and increases the carat weight.

While a fairly common shape, round cut diamonds are the diamond shape that results in the most waste of carats among rough diamonds. Other shapes other than round shape are deeper, have a different shape. What determines the value of a diamond is the amount of waste made in the rough diamond when cutting the diamond to create a particular diamond shape. A diamond shape in which the rough diamond is maintained at high levels tends to be more economically priced.



Other metrics that influence the price of the diamond are availability and popularity. Although there are many diamond cuts, besides the round cut, there are also widely preferred shapes such as Princess, Cushion, Oval, Emerald. However, shapes such as Baguette, Half Moon, Bullet, Trillion, Old Metal, Rose, and Horsehead are among the Exotic shapes. Although there are diamond shapes that have appeared recently, there are many classic shapes that stand up to time, the most classic of which is round. The reason these classics last so long is because they are so successful in revealing the glow.

The diamond shape has always remained popular as jewelers aim to increase the level of luster in each jewelry design. Jewelers follow many ways to design brighter diamond jewelry, and the higher the shine in the ring, the greater the rechargeable. For this reason, there are popular methods to increase the money from a ring. The shapes that are decisive in the appearance of the diamond are now quite common and many people, however, believe that these shallows are an important component of the ring. The source of this popularity is the life of the diamond, the price difference caused by this, and the appearance of the ring.



Different shapes have different tendencies to damage, and some shape diamonds may be more likely to be damaged than other diamonds. For this reason, the most important point to consider when determining the shape is the lifestyle of the person who will wear the jewelry. At the same time, different diamond shapes come in different styles and so some shapes have a more classic look while some have a very modern feel. 

These are the criteria to be considered before buying a diamond. This is because these styles can change the look of the ring one hundred percent. If you are going to determine the diamond shape of an engagement ring, you should choose a shape that suits both your taste and usage, taking into account your personality and usage. If you are looking for a classic cut with versatility, you should know that it can go with any style of clothing and jewelry. Therefore, you don’t need to choose a trend that is only in a trend.



Cut of Diamond

Diamonds are very advanced in terms of optimal transmission of light and radiance. There is a misperception that the cut of a diamond is its shape, but the cut is related to how well the surfaces that make up the diamond interact with light. Sculpting diamond requires highly craftsmanship and delicate artistry. It has symmetry and proportions that allow the reflection of light that can only be unique to a diamond. The best cut in a diamond, the cut that reflects the stone’s value and beauty, is the most difficult to understand technical features among other evaluation criteria (color, clarity, carat).

For the diamond, which is the cutting shape that constitutes most of the diamond jewelry and is, therefore, a standard, the cutting degree is determined by GIA and the proportions of the faces that are effective in the face-up view of the diamond are calculated. As a result, the GIA sets the benchmarks for the best cut of a diamond and makes it possible to evaluate it; The aim is to reveal how successful the interaction between diamond and light is and how much visual effects it creates as a result.



For example, the external and internal white light reflected by a diamond is called “brightness”, the scattering of light to create rainbow colors is called “fire” and the pattern of light and dark areas created by the amount of sparkle produced by a diamond and reflections within the diamond is called scintillation.

The Most Ten Popular Diamond Shapes

The diamond shape is one of the most obvious features of the diamond that distinguishes it from other diamonds at first sight. For this reason, the diamond shapes, which determine a type of identity of the diamond, are cut into certain shapes that have an important role in increasing the brilliance, and the various shapes formed as a result are identified with different situations and characters. Princess cut comes second in popularity after the round brilliant cut, the most common shape among diamond shapes. Although the term to be used is a diamond shape, this feature is often referred to as a diamond cut. While diamonds come in many different types of cut or diamond shapes, the ten most popular shapes are popular and generally preferred for engagement rings or any diamond jewelry:

1. Round Shape

A standard round brilliant cut diamond has 58 surfaces. The 58 facet cuts, divided by the top of the diamond by the “crown”, the widest part “belt”, and the section called the pavilion in between, are calibrated using a precise formula and the aim is to achieve the highest level of shine and fire. In the process of cutting a rough diamond, the loss of the diamond is the highest as a result of the process of obtaining a round diamond, and as a result, the cost of each carat of the round diamond increases. If the diamond cut to create a round cut is successfully cut, the light is accurately reflected and the brightness is maximized.

Although the round cut is popular for engagement rings, it is not only used for making engagement rings; many earrings and necklaces are also quite common among other diamond jewelry. There are many different types of cuts around the world, but the most popular are those used to create engagement rings and jewelry over time. More than 75% of the total diamonds found in the world today are round brilliant diamonds.



The round cut diamond has a different history than other diamond shapes. It took a long time to reveal this shape, which is quite common in the world today. The round-cut, unlike many other diamond cuts, was created by jewelers to achieve the brightest and most faceted diamond, and as a result, an ideal diamond shape for women has been created, with the diamond shape that is always fashionable with elegance and timeless.

The round brilliant diamond cut is classic looking and its design is designed to radiate as much sparkle as possible. A round-shape diamond with a good cut will be effective on the ring with its brilliance and distribution. Even though this shape is not advanced in terms of a-face-up area, its intense glow will make it appear larger than it is. Today, round cut diamonds are cut brilliantly and as a result, these diamonds have more angles and facets. Previously, the cut pattern of diamonds had lighter surfaces and was larger. Although these diamonds are still available on the market, they are harder to find than brilliant round diamonds.



2. Princess Shape

One of the brightest diamond shapes, the princess cut is up to 40% more economical than a round cut diamond. Although the princess cut has slightly smaller facets, the long diagonal measurements it has to make them look larger than they are. The creation process of the diamond cut shape, which is called the princess cut, has been created over many years and after women’s taste has been questioned. Although this cut has a square shape, it is famous for its shine.


Diamond shapes come with different advantages and disadvantages. The advantage of the princess cut is that they are environmentally friendly. Its environmental friendliness is that 80% of the rough diamond is used to make the princess cut diamond, which is that princess cut diamonds are not only beautiful but also more environmentally friendly than other shapes.

The princess cut shape is the second most common shape among all diamond shapes. Although the princess cut has a square shape, the princess cut also has a rectangular shape. The non-sharp rectangular princess cuts cost lower amounts, but in general, the princess cut is to focus on the depth of the diamond to enhance the brilliance. Depth percentages are generally between 70% and 78%. The corners of the princess cut are adjusted for a quad prong setting. This cut shape goes well with long fingers and is also used for wedding bands. If the ration of the princess shape, which can have 57 or 58 faces, is greater than 1.10, then this diamond is called Rectangular Modified Brilliant or square modified-brilliant cut.


3. Cushion Shape

Cushion cut diamonds have a long history and date back to the 19th century. The pillow cut, which is similar to the princess cut in terms of its shape being relatively square, can have many proportions, these proportions can be both square and rectangular. Also, the corners of the stone have a rounded appearance, and these soft corners allow someone with an active life to use it. The cushion cut diamond combines a round diamond with a brilliant cut. It has a romantic atmosphere with 58 large faces and square corners resembling a round appearance.



This cut is also called the “pillow cut”. Its surface is large to increase its brightness. However, diamonds with large faces may be of poor quality with inclusions in terms of clarity. Therefore what needs to be done is to determine the location of the inclusions and evaluate the home. Although the square and rectangular shape of this cut shape are common, the square version is less common but is more symmetrical than the rectangular shape in terms of symmetry. Cushion-cut diamonds are quite successful at reflecting “fire”, the so-called rainbow-colored light reflected from a diamond. These diamonds can be at least 25% more cost than round cut diamonds with equivalent properties.

4. Emerald Shape

The emerald diamond cut is one of the diamond shapes that has a long history. At the same time, this cut was standardized only after 1940 because of its shape close to some of its cuts. At the same time, the quality of the diamond should be kept at a high level while choosing this cut, which is ideal for other precious stones. This is because the style brings out the color in the stone. The emerald cut has a layered finish and is therefore also called a “step cut”. The highlight of the emerald cut is the symmetrical radiance emitted by its symmetrical appearance.

The emerald cut diamond has a total of 58 faces, with roughly 25i in the crown, 25i in the pavilion, and 8i in the sash. For this reason, a more encompassing setting should be chosen, such as a bezel, because light settings such as prong can reveal the color of the diamond.



Emerald cuts have gradual cuts that give off a different kind of sparkle instead of shine and splint. The way the light is reflected in the “room of mirrors”. The emerald cut is one of the least common diamond shapes. However, compared to round cut diamonds, it can cost about 40% less than round cuts of the same carat weight. The elongated look of the emerald cut diamonds makes the fingers look thinner.

5. Radiant Shape

A radiant cut diamond with 70 facets is among the brightest diamond cuts due to the number of facets it has. The reason why Henry Grossbard, the inventor of the radiant cut, invented the brilliant-cut was to blend the good features of the round cut with the good features of the emerald cut. According to jewelry, this cut is more suitable for energetic women. This is because there are many well-cut facets and as a result, the diamond has a highly mobile structure and is hardly noticed among these facets.



The clipped corners of the radiant cut are primarily used for engagement rings. It is also frequently used among other jewelry types because of their versatility. It has more fire compared to the princess cut. This is because the cut corners are preserved. The radiant cut combines the positive aspects of all diamond shapes. There is also a rectangular version for those who are looking for a rounded shape but do not prefer a round cut. Radiant diamonds, which have the highest brightness level that a diamond can scatter, also have a more durable structure. They are also more affordable than round cut diamonds.

6. Asscher Shape

The Asscher cut is relatively old among diamond cuts, originating in 1902. The Asscher cut, which has many curved edges, can be called “octagonal”. Asscher cuts were vintage design cuts that had an original look, unlike other cuts. Although it is vintage, it is a timeless style. At the same time, it has a simple design without exaggeration as a result of its gradual structure.



A large number of surfaces make the appearance of the diamond resemble a soft sparkle from many stones. Featuring an X-look starting from the corners to the middle section, the Asscher cut is a mix of princess and emerald cuts. The shine on the face of the cut conceals the sharpness flaws on the diamond.

7. Marquise Shape

Marquise cut diamond is called by many other names such as boat cut, football cut, eye cut. Although less common among other diamond shapes, it is unmatched by other cut shapes in terms of appeal. It is a cut type that is often used in wedding ring selection and provides versatility. It also has a historical meaning and is among the classics. Marquise, which can be associated with round-shaped and pear-shaped diamonds, is a very harmonious shape with thin and long fingers. 



The marquise cut looks bigger than its weight thanks to the elongated body. This elongated shape makes the diamond look big while making your fingers look slimmer and more elegant. The marquise cut, which has the largest face-up area of ​​all diamond cut shapes, is approximately 15% larger than round cuts and at least 10-25% more affordable than round cuts, even if they have the same carat weight.

8. Pear Shape

It looks like a pear-shaped diamond, just like a teardrop with a slightly larger and flat base. It is designed to create a brighter and magical diamond cut by modeling pear shape, oval and marquise-shaped diamonds. An engagement ring with a pear cut shape has a very unique look and is known by women for their unique features. Pear-shaped diamond shapes are highly productive for creative endeavors.

A pear-shaped diamond is characterized as artistic due to a large number of stylish and elegant variations. This type of cut has 58 facets and with these multiple facets, the light reflects off the diamond, radiating a sparkle and reflecting the light as much as possible. Its body allows the user to point it up or down, and inclusions and imperfections are less likely to appear.


Just like the marquise shape, the pear shape can be wide or elongated and has a thinner showing effect on the fingers. The way to prevent damage and breakage in the form of pear cuts is to add a nail covering the end of the stone. In addition to their unique appearance, it can be said that pear-shaped diamonds, which are quite affordable, are both up to 30% more affordable than round-cut diamonds and larger than them.

9. Oval Shape

The oval cut was first created in the mid-1900s and is a simply elongated diamond, unlike the brilliant, round but round cut. The oval diamond with a round luster attracts attention with its unique shape. The oval cut, which has a larger appearance than a round diamond with the same carat weight, has a highly on-trend look. Because of its elongated shape, what the oval cut shape represents is an immortal affair. The oval diamond, like many other cut shapes, has the feature of making the fingers look thinner and longer, and the stones with this cut are quite compatible with any type of ring.



However, the oval cut shape has rounded edges and is therefore precise. These edges, unlike the thick spots that the marquise cut has, these edges combine the length of the stone with a soft touch in the oval cut. However, what you need to know is that you should be very particular about the color of the stone when choosing this diamond-shaped stone because the rounded ends of the oval cut can be more colored than a round cut diamond. The oval-cut diamonds compete with the brilliance of the round-cut diamonds and also give the fingers a longer appearance. Moreover, it has a larger face-up area of ​​about 10%, and as a result, round-cut diamonds cost much less, up to 30%.

10. Heart Shape

The brilliant-cut and modified heart shape diamond is a beautiful symbol of love and passion. Although the heart shape is generally used with rings, it is also widely preferred in solitaire necklaces made with this shape. It is the symmetry of the heart that must be taken into account when choosing a heart-shaped diamond; both halves of this heart must be the same. The slit in the middle of the two lobes should be sharp.

At the same time, they need to be different and besides that, the round shape of the wings should be very light. If the diamond is small, the heart shape may be less prominent. Therefore, it is recommended that your carat selection for heart-shaped diamonds be not less than 50 carats. If you choose a heart diamond with a carat weight less than this carat weight, the triple prong or bezel setting should be selected. This setting will ensure that the outline of heart-shaped diamonds is more securely preserved.



Heart-shaped diamonds can be both narrow and fat and therefore come in many different styles. If you are considering the heart shape for your pendant, the most preferred size is usually relatively narrow cuts. However, if the diamond is to be used for an engagement ring, a slightly larger size of the diamond is better for the ring’s appearance. Diamonds are subjected to precise measurements so that the ratio of the length of the diamond to its width is determined and as a result, you know the ratio-based shape of the diamond you desire. Also, the symbol of romance, heart-shaped diamonds is up to 30% cheaper than round cut diamonds.

What Is the Difference Between Diamond Shapes and Diamond Cut?

Although the terms “diamond shape” and “diamond cut” are used to mean the same in diamond-related matters, in fact, the concepts they refer to are different. The term in which the term “diamond shape” is confused as “cut” which is among 4C (Clarity, Color, Cut and Carat) and is used as an evaluation criterion.

Although the purpose of cutting diamonds is to create various shapes and this is effective in the brightness and clarity of the shapes, the meaning of the term “cut” refers to the way the light reflects on the stone by making facet arrangement. On the other hand, the shape of a diamond is related to the outer structure of the diamond in question and its outline. For instance, the round, pear-shaped, and pillow diamonds are used to express the true look and shape of the diamond.



On the other hand, it is the size, symmetry, and reflective properties of the diamond that are referred to by a diamond’s cut. For example, the cut of a heart-shaped diamond can be a bright-dull or leather-shallow. These criteria do not determine the shape of the diamond and the shape will remain the heart shape no matter how the diamond is cut. The features that the cut sets are reflective properties such as shine and fire because a diamond whose cut is delicately cut will have higher levels of fire and shine. When choosing a diamond, you must first select the shape and then determine the cutting properties.

The Effect of Diamond Shape on Sparkle

The shapes of the diamonds are cut to maximize the light return. The cuts of these diamonds that reflect the light at the highest level are described as the brilliant-cut. These shapes appear in shapes such as princess, round, oval, pillow, pear, radiant, and the pavilions, which are the belt section of the diamonds, and the facets in the lower part, form a return mechanism where the light is at the maximum level. The diamond is cut in what’s described as “step cuts” to emphasize clarity. The shapes in question both bring out clarity and offer a beautiful glow through the parallel faces they have.



The Effect of Diamond Shape on Price

Although it is a common view that fancy diamonds cost less than round cut diamonds, it can be said that this view is not entirely true. Regarding fancy diamonds, it can be said that their price per carat is generally lower. However, these diamonds are also often smaller in the faces of these diamonds. This is because of the greater carat weight it conceals in its total depth. So an oval-cut diamond of the same carat weight may be more affordable than a round-cut diamond with equivalent properties.

However, you will need to purchase a larger carat weight to get the same visible surface area. With these conditions, you will need to shop comparing to find out which diamond shape suits you. In general, however, everything comes at approximately the same cost considering the average outer diameter. The difference in the raw material price of diamonds is part of the equalization, and the diamond that forms the raw material to obtain a round diamond is more expensive than other diamonds because kava diamond is more compatible with both symmetrical shape and more uniform. On the other hand, princess cut diamonds are obtained with the increased diamond as a result of the round diamond cutting process.

As a result, the shape of the stone and the setting and metal must complement each other in the ideal jewelry, whether it is a jewel that will sparkle in your ears like a pair of earrings, or jewelry bought for special occasions like an engagement ring. In terms of technical features, the round brilliant diamond cut is the one with the most sparkle. Of course, this shine is also and often correlated with the quality of the cut. Another factor in brightness is also size. As mentioned earlier, diamonds in oval, pear, and emerald cuts tend to appear larger than they are. However, what should always be considered is not the diamond with the largest size but the shape that is most ideal for you and the type of jewelry.
