The Top 10 Diamond Shapes and Their Cuts

Diamonds are among the most sought-after gemstones cherished for their brilliance and beauty. However, not all diamonds are created equal, and one of the most significant factors that influence their appearance is their shape and cut. Here, we explore the various diamond shapes and the intricate cutting process.

1. Round Brilliant Cut
The round brilliant cut is the most popular diamond shape, accounting for over half of all diamond sales. This classic shape is designed for maximum sparkle, with 58 facets that reflect light brilliantly. The more facets a diamond has, the more light it can reflect, hence its popularity. The cut's proportions are carefully calculated to enhance the diamond's fire and brilliance, making it a timeless choice for engagement rings and other fine jewellery.

2. Princess Cut
The princess cut is square or rectangular, with pointed corners and numerous facets. Developed in the 1960s, it has become the second most popular diamond shape due to its modern and geometric appearance. The princess cut is known for its exceptional brilliance and versatility. It is often used in various jewellery settings, such as solitaire, three-stone, and halo rings.

3. Emerald Cut
The emerald cut features a rectangular shape with cut corners and a large, open table. Its step-cut facets create a "hall of mirrors" effect, highlighting the diamond's clarity and elegance rather than sparkle. This shape is favoured for its sophisticated and understated beauty.

4. Cushion Cut
The cushion or pillow cut combines a square shape with rounded corners. This vintage-inspired cut has been around for over a century and is prized for its soft, romantic look. Cushion cuts are known for their more significant facets, which can enhance the diamond's brilliance and clarity.

5. Oval Cut
The oval cut is an elongated version of the round brilliant cut, offering similar brilliance but with a unique shape. Its elongated form can create the illusion of a larger diamond, making it a popular choice for those seeking a distinctive yet classic look.

6. Marquise Cut
The marquise cut is an elongated shape with pointed ends resembling a football or a boat. Its dramatic silhouette is designed to maximise carat weight, making the diamond appear larger than it is. The marquise cut is often used in solitaire settings to showcase its unique shape. The elongated shape of the marquise cut creates the illusion of a larger diamond, making it an ideal choice for a single-stone setting.

 7. Pear Cut
The pear or teardrop cut combines the best round and marquise shapes. It features a rounded end and a pointed tip, creating a graceful and elegant appearance. Depending on personal preference, you can wear this versatile shape with the point facing up or down.

8. Asscher Cut
The Asscher cut is square with cut corners and a step-cut facet arrangement, similar to the emerald cut. It was developed in the early 20th century and is known for its art deco aesthetic. The Asscher cut emphasises the diamond's clarity and depth, offering a unique and vintage appeal.

9. Radiant Cut
The radiant cut combines the round cut's brilliance with the emerald cut's shape, resulting in a square or rectangular diamond with cut corners. Its faceted design maximises sparkle, making it a popular choice for a diamond with brilliance and a distinctive shape.

10. Heart Cut
The heart cut symbolises love and romance. It features a unique heart shape with a pointed tip and rounded lobes. This intricate cut requires exceptional skill to achieve perfect symmetry and brilliance.  Jewellers often use heart-shaped diamonds in engagement rings and other romantic jewellery.

The Cutting Process
Cutting a diamond involves transforming a rough stone into a polished gem with precise angles and facets. The process begins with planning, where the cutter assesses the rough diamond to determine the best shape and cut. Advanced technology, such as computer modelling, helps maximise the diamond's potential.

The rough diamond is then cleaved or sawed into smaller pieces. Next, bruting shapes the diamond into a basic outline. Faceting, where the cutter meticulously adds facets to enhance the stone's brilliance, follows. Finally, the diamond is polished to achieve its final shine.

Conclusion
Understanding the different diamond shapes and how they are cut can help you make an informed decision when selecting diamond jewellery. Each shape has its unique characteristics and beauty, reflecting both the cutter's skill and the diamond's inherent qualities. Whether you prefer the classic round brilliant or the elegant emerald cut, there's a diamond shape to suit every taste and style.
