Buying an Engagement Ring? Here are the most popular diamond shapes

The shape of your diamond will have a great deal of impact on the look of your fiancée's ring, whether it is round or cushion-cut. In addition, it could have a significant impact on the ring's price. This article will provide an overview of each diamond shape and point you in the right direction for your diamond purchase.

Do not confuse Diamond Shape with Diamond Cut

Diamond shape and diamond cut are often used interchangeably when it comes to diamonds, but they’re actually quite distinct terms.

The outline or external figure of a diamond can be determined by its shape. Pear-shaped, round brilliant, and cushion, for example, all refer to the diamond's physical shape and appearance.

The cut of a diamond refers to the facets, symmetry, dimensions, and reflective qualities of the diamond. A heart-shaped diamond, for instance, may be cut shallow or deep, dull or brilliant. These factors don’t affect the shape of the diamond — after all, it’s still heart-shaped — but they do affect its cut. The finer the cut of a diamond, the greater the level of brilliance and fire.

To find your ideal diamond, first, select the desired shape. Then work toward finding that shape in the most appealing cut.

Our diamond shapes guide will help you maximise the value you get within your budget with your desired taste and style.


1. Round Brilliant Cut Diamonds

As the leading diamond ring shape in terms of popularity, the Round Brilliant Cut represents over two-thirds of the diamonds sold.The precise shape of a round diamond provides for maximum light reflection, adding to its exceptional brilliance. There are 58 facets in Round Brilliant Cuts (including the culet).

2. Princess Cut Diamonds

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.

3. Emerald Cut Diamonds

This diamond ring shape gets its name from the process that was initially used to cut emeralds. The Emerald Cut Diamond's broad table surface allows for a lot of reflections thanks to its long, straight lines or 'steps.' Emerald Cuts can be found in both square and rectangle designs.

4. Cushion Cut Diamonds

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. Different from other diamond ring shapes, the Cushion Cut can be designed in many variations, including standard, modified, and modern.

5. Asscher Cut Diamonds

After its one-hundredth anniversary and a small change to the cut technique, the Asscher Cut Diamond regained popularity in 2002. It was first manufactured by the Asscher Brothers of Holland in 1902. The Asscher Cut Diamond is a stunning alternative to the Emerald Cut, with a smaller table and more layered facets. Light refracts between the square facets beneath the table, resulting in brilliance. Trimmed corners give the Asscher Cut further beauty and stability.

6. Pear Shaped Diamond

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.

Length to width ratio: The classic length to width ratio ranges from 1.45-1.75. Reviewing a variety of ratios will give you an idea of personal preference. You may wish, for example, for a wider or more narrow shape.

7. Oval Diamonds

8. Heart Shaped Diamond

A prominent symbol of love, the Heart Shaped Diamond boasts an exquisite figure that can be set in a ring, pendant, or another 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.

9. Radiant Cut Diamonds

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.

10. Marquise Diamond

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 shape of the Marquise 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.
