Your guide to diamond shapes and diamond cuts by Georgina Yvonne.

Shapes & Cuts

The Difference Between Shape and Cut

When choosing a diamond, its shape and cut are among the most important factors to consider. While these terms are often used interchangeably, they have distinct meanings:
Shape refers to the geometric outline of the diamond (e.g., round, oval, princess).
Cut refers to how well the diamond’s facets are crafted to maximize its brilliance, fire, and sparkle.

Shapes & Cuts

Round Brilliant Cut

The round brilliant is the most iconic and popular diamond shape, loved for its timeless elegance and unparalleled sparkle. Its 58 facets are designed to maximize light reflection, making it the most brilliant shape available.
This cut is best for classic engagement rings, solitaire settings, and maximum brilliance.
We recommend focusing on Excellent or Ideal cut grades to achieve the best sparkle.

Shapes & Cuts

Princess Cut

The princess cut is a modern square shape with sharp corners and brilliant faceting that creates exceptional fire and sparkle. It’s the most popular square diamond shape and a favourite for contemporary designs.
This cut is best for modern, geometric styles, and versatile settings.
We recommend looking for symmetrical proportions to avoid a dull appearance.

Shapes & Cuts

Cushion Cut

Also known as the “pillow cut,” the cushion combines a square or rectangular shape with rounded corners. Its vintage charm and soft edges make it a romantic choice.
This cut is best for vintage-inspired settings and designs with a touch of softness.
We recommend opting for a cushion modified cut for added brilliance.

Shapes & Cuts

Oval Cut

The oval shape elongates the finger and offers a similar brilliance to the round cut. Its elegant and elongated design makes it a popular choice for those seeking something unique yet timeless.
This shape is best for sleek, elongated styles and rings with a contemporary edge.
We recommend ensuring symmetry to avoid a "bow-tie" effect in the centre.

Shapes & Cuts

Emerald Cut

The emerald cut is a rectangular shape with step-cut facets that create a “hall of mirrors” effect. It emphasizes clarity over brilliance, offering a sophisticated and understated sparkle.
This cut is best for minimalist designs and showcasing high-clarity diamonds.
We recommend focusing on clarity and color, as inclusions are more visible in step cuts.

Shapes & Cuts

Radiant Cut

Combining the brilliance of the round cut with the shape of the emerald cut, the radiant cut is a hybrid that sparkles beautifully. Its trimmed corners make it a versatile and durable choice.
This cut is best for those seeking brilliance with a unique twist.
We recommend looking for excellent symmetry to enhance light reflection.

Shapes & Cuts

Pear Cut

Resembling a teardrop, the pear-shaped diamond is a blend of round and marquise cuts. Its unique silhouette is both elegant and dramatic, often chosen for its slimming effect on the finger.
This cut is best For unique, artistic designs and pendants.
We recommend ensuring a well-balanced shape and avoid visible asymmetry.

Shapes & Cuts

Marquise Cut

With its elongated shape and pointed ends, the marquise cut maximizes carat weight and creates a bold, regal look. Its history is steeped in luxury and grandeur.
This cut is best For vintage-inspired designs and maximizing perceived size.
We recommend paying attention to symmetry as this is critical to avoid a lopsided appearance.

Shapes & Cuts

Asscher Cut

Similar to the emerald cut but square, the Asscher cut is a vintage design with step-cut facets that create a mesmerizing geometric effect.
This cut is best for Art Deco-inspired designs and high-clarity diamonds.
We recommend prioritising clarity and a high-quality polish.

Shapes & Cuts

Heart Cut

The heart-shaped diamond is a symbol of love and romance, making it a meaningful choice for engagement rings and special occasions.

This cut is best for statement designs and romantic gestures.

Choosing Your Perfect Shape

When selecting a diamond shape and cut, we recommend:
Considering Your Personal Style: Classic shapes like round and oval are timeless, while pear and marquise are perfect for a modern, unique design.
Think About Setting: Certain shapes pair better with specific settings (e.g., emerald cuts shine in simple solitaire designs).
Set Your Price Point: Fancy shapes often offer better value per carat compared to round diamonds.
