Knowing the basic information about diamond shapes will help you select the perfect diamond for you or a loved one.
As the leading diamond shape in terms of popularity, the Round Brilliant Cut represents over two thirds of the diamonds sold.
In 1919, Marcel Tolkowsky published, “Diamond Design: A Study of the Reflection and Refraction of Light in Diamond,” which explained the ideal angles for a diamond to produce the highest level of brilliance and fire. His work created a surge in the Round Brilliant Cut’s popularity, which remains consistent today.
The Round Brilliant’s refined shape allows for maximum reflection of light, contributing to its incredible brilliance. Round Brilliant Cuts have 58 facets (including the culet).
The Round Brilliant Cut is popular for many reasons, one being that it provides exceptional brilliance and a classic, ageless look. Round Brilliant Cut diamonds are stunning choices for engagement rings, necklaces and other fine pieces.
This fancy cut shape is second in diamond popularity after the Round Brilliant Cut. It’s created from the inverted pyramid of the rough diamond stone. Traditionally square, the Princess Cut achieves greater brilliance and fire than other similarly shaped diamonds.
The Princess Cut allows for a square outline while still offering nearly the same brilliance as the Round Brilliant Cut. Due to the larger yield maintained from cutting for a Princess, the price per carat is usually much lower than the Round Cut.
Using the technique originally designed to cut emeralds, this diamond shape comes rightly by its name. With its large table surface, the Emerald Cut Diamond offers abundant reflections through its long, straight lines or ‘steps.’
Most notably, the Emerald Cut showcases size better than other diamonds of the same carat. Emerald Cuts are a premium choice for those desiring a larger piece without an enormous price tag.
The Cushion Cut Diamond gets its name from the combination of a square shape with rounded edges, making it look like a pillow or cushion. Due to its precise bending and dispersion of light, the Cushion Cut beams with fire.
Choosing a Cushion Diamond offers creativity and personalization. Cushions also have the luxurious appeal of a classic fashion along with modern fire and flair.
First produced by the Asscher Brothers of Holland in 1902, the Asscher Cut Diamond regained popularity in 2002 after its one hundredth anniversary and a slight modification to the cut technique.
As a dazzling alternative to the Emerald Cut, the Asscher Cut Diamond hosts a smaller table and more layered facets. Brilliance is achieved through light reflection among the square facets seen underneath the table. The Asscher Cut’s trimmed corners give it extra style and stability.
More Info: The Asscher Cut’s deep pavilion and precision creates an enamouring appeal. While similar to the Emerald Cut, the Asscher tends to offer a bit more sparkle, due to its high crown and 58 facets.
With a rounded side that narrows to a distinct point, the Pear Shaped Diamond is an elegant, timeless choice. If purchasing for a ring, the pointed end will point toward the heart of the wearer. Symmetry is critical to the appearance of a Pear Shaped Diamond so it shimmers evenly.
More info: A Pear Shaped Diamond makes for an enchanting engagement ring. Because well-cut Pear shapes are harder to find, it’s an exquisite alternative to traditional cuts like the round diamond. The Pear Shaped also hides inclusions well.
Showcasing similar brilliance and fire to the Round Cut, the Oval Diamond is an exquisite choice for those who wish to wear a unique shape. The Oval’s elongated silhouette offers a large appearance compared to other shapes of the same carat.
Strong points:This fancy length diamond is durable because it carries no pointed edges.
A prominent symbol of love, the Heart Shaped Diamond boasts an exquisite figure that can be set in a ring, pendant or other jewelry piece. Heart Shaped diamonds range in slenderness and width, selected primarily on personal preference. A well-cut Heart Shaped Diamond should be symmetrical, so it appears balanced and full. The point or cleft of the diamond should be distinct.
Radiant Cut Diamonds gained their popularity in the 1980s due to their dazzling brilliance which is only exceeded by the Round Brilliant.
The Radiant Cut is an enchanting choice due to its numerous facets found in the pavilion and crown. These features provide a high level of both brilliance and fire. Its cropped corners also make it a delightful match for pairing with rounded or square diamonds.
Originally requested by King Louis XIV to mimic the shape of his mistress’ mouth, the Marquise Diamond has remained a flattering and delightful choice for several centuries.
The narrow body of the Marquise Diamond resembles the shape of an elongated eye. Its stunning large crown is complementary to wearers as it makes the finger appear longer and more slender.
The Marquise’s elongated figure gives the appearance of a larger stone when compared to other shapes in the same carat. Making the fingers of the wearer look thinner and longer, the Marquise shines brightly and is usually noticed for its unique shape.
Showcasing 24 parallel facets, the Baguette Diamond hosts long, parallel lines and remarkable clarity. Rectangular in shape with step cutting, Baguettes make for vibrant ring center pieces and graceful side stones.
The long bar shape of the Baguette offers exceptional size even at a low carat. Its clarity and appealing symmetry make it a classic and timeless diamond.
Trillion Diamonds, also known as trilliant diamonds, are incredibly enchanting and unique. Different than round, square or rectangular shapes, the Trillion almost always makes an impression.
With their rich brilliance and deep fire, Trillions diverge from popular shapes yet are just as exquisite.The personality of the Trillion is perhaps its strongest asset. The sharp, unique features create a dashing look, maximized by the Trillion’s immense width. For this reason, Trillions tend to look larger than other diamonds of the same carat weight.
