Understanding Diamond Shapes: A Guide to Choosing Your Perfect Gem

When selecting a diamond, its shape is just as important as its clarity, color, and carat weight. Diamond shape refers to the geometric appearance of a diamond, distinguishing it from diamond cut. Diamond shapes, often referred to as cuts, play a crucial role in determining the stone’s overall appearance and brilliance. Whether you’re in the market for an engagement ring or a special piece of jewelry, understanding the different diamond shapes will help you make an informed decision that matches your personal style. Here’s an in-depth look at the most popular diamond shapes and cuts to help you discover which one suits you best.

The Timeless Appeal of Round Cut Diamonds

The round cut diamond remains the most popular choice among buyers, prized for its versatility and exceptional ability to reflect light. This popular diamond shape, known as the round brilliant cut, features over 56 meticulously crafted facets that optimize light refraction, resulting in a brilliance and fire that is superior to other diamond shapes. The round brilliant diamond is highly popular and optimized for brilliance, making it a top choice for modern engagement ring styles. Its symmetry and balance make it a perennial favorite, ideal for those who appreciate classic beauty and elegance.

Elegant and Unique: Pear-Cut Diamonds

Pear shaped diamonds, also known as teardrop diamonds, combine elements of round brilliant and marquise styles, featuring oval diamonds with one rounded end and a pointed tip. This distinctive shape is reminiscent of a sparkling droplet of water, making it an excellent choice for individuals looking for a blend of tradition and unique flair. The pear cut’s elegant contours are perfect for creating a soft, feminine look that elongates the finger when set in a ring.

Vintage Charm of Cushion-Cut Diamonds

Originating in the 1800s, the cushion-cut diamond is a blend of historical charm and modern technology. Known for its pillow-like shape with rounded corners and sides, this diamond cut has gained a reputation for its romantic, soft look. Modern cushion cuts often feature brilliant faceting, enhancing their appeal and making them a fantastic choice for vintage-inspired jewelry.

The Brilliant Radiance of Radiant Cut Diamonds

Radiant cut diamonds are a stunning synthesis of traditional, round diamonds and elegant emerald cuts, combining the brilliance of a brilliant cut with the silhouette and geometry of an emerald. Featuring 70 brilliant facets, these diamonds are cut to emit an immense amount of radiance and help hide inclusions. With its trimmed corners and a sophisticated blend of facets, the radiant cut is ideal for those who seek a lively diamond that combines classic and contemporary elements.

Asscher Cut Diamonds: A Touch of Royal Elegance

Developed in 1902 by Joseph Asscher, the Asscher cut diamond is renowned round diamond, for its sophisticated, almost architectural look, thanks to its cropped corners and unique facet pattern. This cut is perfect for those who adore vintage style and want a diamond that offers depth and drama, accentuated by its distinctive angled cuts.

Contemporary Beauty: Princess-Cut Diamonds

The princess cut is a modern favorite next only to the round cut in popularity. Known for its sharp, uncut corners and beautiful symmetrical shape, this diamond is cut into either a perfect square shape or slightly rectangular shape. The princess cut is highly sought after for its contemporary beauty and excellent use of rough stone, yielding more carat weight from the raw diamond.

Among the various types of diamond cuts, the princess cut stands out as one of the most popular shape with many options available, each offering unique qualities and shapes.

The Understated Elegance of Emerald-Cut Diamonds

With its long, rectangular shape and step-cut facets, the emerald cut diamond is a study in sophistication. When compared to other shapes of rough diamond, like the oval cut, both give the illusion of a higher carat diamond when set into a ring. This cut highlights a diamond’s clarity better than any other cut. The broad, flat plane of this diamond showcases the stone’s natural color and inclusions, requiring a high level of clarity. It’s ideal for those who appreciate a subtle, understated look with a powerful presence.

Dramatic Flair of Marquise-Cut Diamonds

The marquise cut diamond features an elongated shape with pointed ends, optimized to maximize carat weight, giving the illusion of a much larger diamond. This cut can elongate the finger and add a touch of elegance to any setting. Its history traces back to royal courts, making it perfect for those who want a diamond with both a story and a striking appearance.

Romantic and Rare: Heart-Shaped Diamonds

Heart-shaped diamonds are a testament to skillful diamond cutting, and their unique shape makes them a rare and enchanting choice. Symbolizing love and romance, these diamonds are perfect for special occasions like anniversaries and engagements. The complexity of cutting a perfect heart oval diamond shape makes these diamonds particularly special and sought-after.

Heart-shaped diamonds are also a popular choice for engagement rings, symbolizing deep love and commitment.


Choosing the right diamond shape involves understanding both the style and the technical attributes of each cut. Whether you prefer the brilliant sparkle of a round cut, the elegant elongation of a pear cut, a fancy shaped diamond or the vintage allure of a cushion cut, each shape offers something unique. Popular diamond shapes, such as the round brilliant, oval, princess, emerald, cushion, pear, and heart shapes, appeal to different preferences and styles. Remember to consider how each diamond shape will look on your hand and how it reflects your personal style. When selecting your diamond, ensure that you purchase from reputable jewelers who provide quality cuts that enhance the stone’s natural beauty. By understanding the various options available, you can select a diamond that not only meets your aesthetic criteria but also represents a cherished investment in lasting beauty.
