When most people think about diamonds, they picture the classic and popular round shape. But if you prefer something different, there are plenty of other types of diamond cuts and shapes available to reflect your

what is a diamond shape?
A diamond shape refers to the outline or form of a diamond when viewed from above, and it plays a major role in the stone's overall appearance and sparkle. Diamond cuts range from the classic round brilliant to elegant ovals, striking emerald cuts and romantic hearts. Each of the different diamond cuts adhere to specific proportions and angles, which affect how the diamond reflects light, giving each shape its own unique brilliance and fire. Whether you’re drawn to something timeless or trendsetting, the shape of your diamond is key to creating the perfect ring.
different types of diamond cuts

round brilliant cut diamonds
Thanks to its 58 expertly placed facets, the round brilliant cut maximizes light return, giving it unmatched brilliance and fire. This type of diamond shape offers the greatest amount of flexibility in terms of balancing cut, color, clarity grade and price. Whether set in a solitaire, halo or vintage-inspired setting, round brilliant diamonds remain timeless and ever popular.

princess cut diamonds
The princess cut diamond has a square shape with sharp angles and a similar facet pattern as the round brilliant diamond, so it sparkles more than other square cuts. Sophisticated and eye-catching, the princess cut provides symmetry, clean lines and a modern design.
This different cut of diamond makes it one of the most popular choices for engagement rings after the round brilliant. The princess cut’s sharp corners and pyramidal shape also help to hide inclusions well, making it a great option for maximizing visual impact. It's especially stunning in settings that emphasize its crisp edges, such as channel or bezel styles

cushion cut diamonds
A cushion cut diamond is a square or rectangular shape with rounded corners, like a cross between a round and a princess cut diamond. Often referred to as a “pillow cut” because of its soft, rounded edges, this diamond shape exudes a vintage charm and romantic appeal. Cushion cut diamonds come in a variety of facet patterns, such as the classic “chunky” style or the more modern “crushed ice” look, offering options for every taste. The diamond cuts work beautifully in halo settings or as solitaires and pair well with both modern and vintage-inspired bands.

emerald cut diamonds
Although the emerald cut diamond has the same number of facets as round and princess cut diamonds, it is the parallel facets that help highlight the stone’s color and clarity. The best way to describe the emerald cut is a rectangular shape designed with a large table and step-cut faceting that creates a unique hall-of-mirrors effect. This geometric diamond shape is rare: only 3 percent of all the diamonds in the world are emerald cut diamonds. Because of its open, linear design, the emerald cut tends to reveal inclusions and color more easily, so selecting a higher clarity and color grade is often recommended. This cut pairs perfectly with Art Deco, minimalist and vintage-inspired settings.

oval cut diamonds
The oval diamond shape has an elongated silhouette that helps it appear larger than other diamonds of a similar carat weight, offering maximum visual impact. A brilliant facet pattern, soft curves and a graceful shape give the oval cut that timelessly elegant feel that flatters the finger by creating a lengthening effect. Try an oval cut diamond set east-west for a trendy twist, or go with a classic north-south orientation.

marquise cut diamonds
The marquise shape is an elongated oval with pointed ends and is sometimes referred to as boat-shaped due to its distinctive silhouette. Originally commissioned by King Louis XV of France, the marquise cut diamond exudes royalty and sophistication. Its elongated shape maximizes the carat weight of the diamond, meaning you get more visible surface area compared to other cuts of the same weight. This not only enhances the finger-lengthening effect but also creates the illusion of a larger diamond. The pointed tips of the marquise diamond cut add a bold, dramatic flair, while its brilliant facet pattern ensures plenty of sparkle and light return. Consider pairing this diamond with tapered baguette accent stones or a halo of smaller diamonds.

pear cut diamonds
The pear cut’s elongated teardrop has a narrow pointed top and a perfectly rounded bottom, combining the best of both the round and marquise cuts. This versatile diamond shape offers a unique and elegant look that stands out from more traditional styles. Known for its high sparkle, the elegant pear shape helps to lengthen and flatter its wearer's finger, creating a graceful, slimming effect. Pear cut diamonds can be worn with the point facing up or down, offering a personalized touch to the ring’s design. This type of diamond cut also works beautifully in a variety of settings, from minimalist solitaires to elaborate halos or vintage-inspired bands.

radiant cut diamonds
Radiant cut diamonds have a rectangular shape with cropped corners, giving them a bold yet refined look. This cut of diamond combines the clean lines of an emerald cut with the brilliance of a round, thanks to its complete brilliant cut facet pattern. Radiant diamonds are available in both square and more elongated rectangular shapes, depending on their length-to-width ratio, offering flexibility for different style preferences. Their faceting helps hide inclusions well, making them a great option for maximizing beauty and value. These diamond cuts promise incredible sparkle and are usually set in prong-style solitaire settings that further highlight their brilliance.

asscher cut diamonds
Developed during the Art Deco period, the Asscher cut diamond is a blend of the princess and emerald cut, featuring the step-cut facets of an emerald with the square outline of a princess cut. Its deep pavilion and high crown give it exceptional depth and brilliance, creating a distinctive hall-of-mirrors effect. The asscher’s X-shaped facets offer a hypnotic, geometric symmetry that draws the eye inward. It looks stunning in settings that reflect its heritage, such as Art Deco-inspired designs or solitaire styles that let the cut shine on its own.

heart-shaped diamonds
Wear your love loud and proud with a bold symbol of romance: a heart-shaped diamond. Whimsical and sweet, a heart-shaped diamond gets cut into the unmistakable shape of a heart. This cut of diamond requires expert craftsmanship to balance symmetry and maximize brilliance, as even slight imperfections can affect the overall look. Because of its unique silhouette, it works best with settings that protect the delicate points while showcasing its romantic form, such as prong or bezel styles.
how are diamonds cut into shapes?
Diamond cutting is a highly precise and technical process that transforms rough stones into dazzling gems with carefully crafted shapes and facets. Initially, the rough diamond is examined and mapped using advanced imaging technology, such as 3D scanners and laser mapping, to determine the best way to maximize carat weight, clarity, and brilliance. The wedding ring cutting process begins with cleaving or sawing, where a laser or steel blade is used to split the rough diamond along its natural grain lines or crystal planes.
After sawing, the diamond undergoes bruting or girdling, where two diamonds are rubbed together or shaped by a spinning wheel to create the basic outline or shape. The most critical and intricate phase is faceting, where skilled cutters use precise angles and proportions to create multiple flat surfaces called facets. These facets are engineered to optimize the diamond’s ability to refract and reflect light, enhancing brilliance, fire and scintillation. Cutters rely on mathematical calculations and extensive experience to determine facet arrangement and angles unique to each diamond shape. Polishing is the final step, ensuring each facet is smooth and perfectly aligned to meet strict industry standards.
