Diamond shapes refer to the shape of the diamond. It is the most common premise for consumers to differentiate diamonds when they begin their search for the perfect diamond for their dream ring.
It is easy to confuse diamond shapes with diamond cuts. Diamond cuts or diamond shapes are a part of the 4Cs of diamonds – cut, clarity, carat, and color.
Many diamond shapes are named after the people who first produced them, others are named based on their look and shape. However, Cut & Shape are not the same. A diamond’s cut refers to the angles and proportions in which the diamond has been cut to bring out its brilliance.
Depending on the clarity and symmetry of the light and dark spaces formed by the reflection of light, a diamond’s cut can be classified into categories like Excellent Cut, Very Good Cut, and Good Cut. The diamond shapes, on the other hand, determine its look and image.
Diamond shapes include round, princess, oval, marquise, pear, cushion, emerald, asscher, radiant, and heart. Of these, the round, cushion, and princess are the very classic choices that just never go out of style. However, elongated diamond shapes like the marquise, emerald, and oval are also becoming pretty popular among diamond lovers.
Round Shape Diamonds
The round diamond shape is a classic choice and probably one of the oldest and most classic styles. Due to the brilliance of this shape, it gives a uniform and symmetrical look. This is also one of the shapes where diamond lovers usually go for an excellent cut diamond with exactly 58 facets. This ensures it shines bright and has high fire because of optimum reflection.
When it comes to pricing, a round-shaped diamond usually commands a higher market price compared to other popular diamond shapes. This is primarily because of two reasons. First, round shape is immensely popular which contributes to their high market demand. As per market data, around 40% of diamond lovers choose round shaped diamonds.
Diamond manufacturers globally put a premium pricing on round shaped diamonds. Second, cutting and polishing a round diamond from the rough, creates maximum wastage, making it difficult to produce. But there are a few other diamond shapes that come close to the popularity and grace of the round diamond.
An Oval shape diamond has the brilliance of the round diamonds combined with a unique elongated shape. It has a very rich history though it is one of the ‘newer’ diamond shapes. As a variation of the round cut, many jewelers had been experimenting with similar oval shapes. However, the oval diamond, as we know it today, was not developed until the 1960s. Lazare Kaplan, a diamond cutter from Russia, had the reputation for turning the wasted pieces of diamond into something useful. He could create smaller, workable diamonds from damaged gemstones by throwing away the damaged parts and putting in a little extra work. He was responsible for developing the oval shaped diamond as we know it, from a piece of deformed diamond.
Due to their shape and design, oval diamonds require less depth and have a fuller look. If a diamond of this shape is cut a little too deep or shallow, it can emit a bow-tie effect. A bow-tie is a dark pattern running across the width of the diamond, generally across the center. Minimal bow-tie makes oval diamonds more beautiful and clean.
The right setting can make your oval shaped diamond engagement ring gorgeous and out-of-this-world. Oval cut diamonds can go with any settings but it can look extra-beautiful in solitaire and halo settings. Pavé and side-stone settings can make it even more elegant. Oval diamond engagement rings are rather popular among many Hollywood celebrities too. Pop singer, Justin Bieber’s fiancé Hailey Baldwin captured our attention with a large oval diamond set on an 18K gold band. It was estimated to cost around $250,000.
A pear shape diamond resembles the shape of a teardrop which is basically a combination of a round and a marquise diamond with one end tapered and pointed. It is a vintage and very poignant shape with facets similar to the round diamond. This is why pear diamonds have the same beautiful shine and sparkle like round diamonds. However, to get the best sparkle, a pear diamond should have well-defined symmetry.
Pear shaped diamonds, like oval shapes, can have the bow-tie effect. But if the diamond is well-cut, the bow-tie effect is minimal. The origin of the teardrop diamond can be traced back to 1458 Belgium. A Polish diamond polisher Louis Van Berquem (Lodewyk) created the shape using scaif, a polishing wheel he had invented. Eventually, this shape gained more popularity in the Renaissance Period. Given its shape, the pear shaped diamond does not create a lot of rough wastage because it is able to use odd shapes to its benefit. This is why the diamond, even though popular and brilliant in its performance, does not command a premium as round cut or princess shaped diamonds.
A pear diamond engagement ring can be worn with the tip facing away from the fingers or towards it. Famous singer, Victoria Beckham, flaunted a magnificent 17-carat pear diamond back in 2005. Pear shaped diamonds can sit gorgeously in a halo setting or a solitaire setting. Pear diamonds are also great as shiny earrings. However, you should keep the width of the diamond in mind before selecting a setting.

Princess Shape Diamonds
True to its name, a princess cut diamond commands royalty in the diamond industry. This shape belongs to the family of square diamonds and is quite popular across age groups. The shape is usually a square or a rectangle with pointed corners and 76 small facets. Though the princess shape may have four sides like an Emerald or Asscher shaped diamond, it does not give out flashes of lights like the other fancy shapes. Rather, like the cushion or round cut, it has a dazzling sparkle. Cameron Diaz boasted a lovely sparkling princess diamond ring during her engagement with Benji Madden that catapulted this shape on the popularity charts.
The elegant princess shaped diamond was known as the profile cut. In 1961, a London-based diamond cutter named Arpad Nagy created the profile cut. It was only after a few years that other experts in town popularized this shape with its new name, the princess diamond.
Setting is important for princess shape diamonds because the hard edges of the diamond can get chipped if the setting is not secure. A princess shape diamond looks great when paired with a four prong setting or a channel setting or even in a classic solitaire setting. However, you can make it even more gorgeous if you go for the halo setting or the three-stone setting.
Emerald Shape Diamonds
Unlike brilliant cuts, Emerald shape diamonds are based on step-cuts. Brilliant cuts in shapes like round or cushion shapes resemble a pattern of kites and stars in symmetry. But an emerald diamond resembles rectangular facets arranged like steps or stairs. When viewed from the top, it looks like a large open table because of its shape and the arrangement of the cut. The steps play with the light and dark spots to create a hall-of-mirrors effect.
The sparkle of an emerald diamond is quite subtle and subdued. Due to its elongated, rectangular body, it has a bigger visual appeal. Officially, the term “emerald cut” came into use around the 1920s. However, it is believed that this cut has been popular since the 1500s as the “table cut”, much before diamonds were used in jewelry. Originally the shape was developed for cutting emeralds – the inspiration behind this diamond shape’s name. Emerald-shaped diamonds show many similarities to the Asscher shaped diamonds.
No wonder, this shape is a hit among Hollywood stars too. Jennifer Lopez captured the internet when she received a 15-carat emerald diamond ring from A-Rod in 2019. Even Kim Kardashian stunned her fans with the sparkling beauty of her massive 16.5-carat emerald diamond ring. (edited)
A cushion shape diamond resembles a cushion or a pillow, hence the name. Initially, cushion shape diamonds were known as the mine cut or old mine cut diamonds as they have been around for more than 200 years now! The cushion diamond spent the first 100 years of its existence being supremely popular, just as the round cut does at present. Previously, cushion diamonds were square diamonds with rounded corners. They were named after the Brazilian diamond mines, from where they were extracted. The initial cut had 58 total facets. The modern cushion cut has 64 facets which adds to its brilliance, more than the original shape ever did. The recent developments in their designs have made the cushion shape quite popular today.
If you look at a cushion-shaped diamond, you’ll notice that they are either square or rectangular, quite similar to the princess shape. What makes them unique is their rounded corners which gives them a soft appeal. While the brilliance of round diamonds remains unmatched, well-cut cushion shaped diamonds can outshine round diamonds in terms of fire. When set in a 4-prong design, the cushion shape looks absolutely gorgeous.
The history of the Asscher shape diamond dates back to 1902. The Asscher brothers found the Asscher Diamond Company based in Amsterdam/Holland. Now it is known as the Royal Asscher Diamond Company. Joseph Asscher created the original Asscher cut, which featured 58 facets. In fact, it was a patented design for many years and only the Asscher family could produce the Asscher diamond up until the second world war. The Second World War destroyed Amsterdam as the diamond-polishing capital of the world. As a result, the Asscher family was deported to the Netherlands. Gradually, the surviving members of the family returned and tried to rebuild the company. Soon after, the Queen of Holland granted them the royal title. Over the years, the Asscher family made improvements to the Asscher diamond. Today, the diamond shape has an international patent!
The current Asscher shape diamond design has X-shaped facets that flow from the corners to the center of the stone. It is a blend of the princess cut and the emerald cut and is developed using modern tools and technologies. Now, it features 78 facets – a major improvement from the original design with 58 facets. The crown of the diamond has been raised to introduce more facets in the design. These facets help in a clearer, more symmetrical reflection of light. Given its history, the Asscher shape diamond boasts of a vintage appeal. Despite all the new additions and changes made to the design, the Asscher-shaped diamond cut has been able to retain its simplistic and graceful look.
The radiant shape diamond is an octagonal diamond, designed by Henry Grossbard in 1976. It is a very modern and perfectly symmetrical design. The radiant shape combines the best of a round-shaped diamond and an emerald-shaped diamond.
The clean lines and corners make it look like an emerald-shape diamond while the facets are similar to round-shaped diamonds, giving it that stunning sparkle. It is an elongated hybrid diamond and can make your fingers look slim and beautiful. A radiant diamond has around 70 facets and it turns up the brilliance of the diamond. It is a non-traditional fancy shape and falls within the list of elongated looking diamonds. No surprises that this shape is making a big comeback.
Depending on how you want the radiant diamond to look on your finger, you should choose the right setting. For example, a 4-prong or a 6-prong setting is most becoming for this shape. A stunning 14K white gold setting can really spark joy for your radiant diamond. However, if you are confused about the setting or you just wish to buy loose diamonds in this shape, it would be best to consult a diamond concierge from LovBe.
What is the hardest diamond shape to cut?
All diamond shapes have their own unique appeal. For example, the emerald shape diamond may not be the most brilliant but can give a hall-of-mirrors look that is much loved by celebrities like Jennifer Lopez. On the other hand, oval-shaped diamonds can really bring out a diamond’s brilliance. However, the attractiveness of a diamond is not just defined by its shape.
What makes a diamond shine is the right cut and the right shape. Admittedly, a few challenging shapes require more precise cuts that lead to wastage, making the price of the shape higher. Among all the existing diamond shapes, the most popular round shape diamond is the hardest diamond shape to cut. Some of the reasons that make it hard to cut include:
- Precisely-cut facets: Round shape diamond is the hardest diamond shape to cut because it requires precision to create 58 facets. These facets act like tiny prisms and come together to maximize the reflection and brilliance (fire) of the diamond. It requires a lot of intricate detail work making it a hard-to-cut shape.
- Hearts and Arrow cut: The cut of the round diamond makes sure that the diamond has the right symmetry while reflecting the maximum light. The hearts and arrow cut for round shape diamonds is the most challenging cut as it demands a high level of precision. The diamond cutter needs to precisely measure and cut the diamond, keeping in mind the angles and symmetry. When viewing a heart and arrow cut diamonds with a special tool, you can see the arrows (when seen from top) and the hearts (when seen from face-down). It is this degree of skilled craftsmanship that makes the hearts and arrow cut one of the most stellar diamonds you’ll ever lay eyes on!
In the case of naturally mined diamonds, the shape of the diamond unearthed majorly decides the amount of work required to cut a round-shaped diamond. However, in the case of lab grown diamonds, wastage can be minimized, allowing to fashion out diamond shapes more efficiently. Even though round-shaped diamonds can be the hardest diamond shape to cut, other shapes like the princess, ovals, emerald and Asscher shapes also require a high level of precision.
