Choosing a diamond is a deeply personal decision, and one of the most important factors is diamond shape. While cut quality affects brilliance, the shape defines the diamond’s personality, visual appeal, and how it reflects your individual style. From timeless classics to modern statement shapes, each diamond shape tells a story.

In this guide, we compare the most popular diamond shapes, explain their unique characteristics, and help you discover which shape best suits your lifestyle, aesthetic, and values.

Why Diamond Shape Matters

Diamond shape refers to the outline or form of a diamond when viewed from above. Unlike cut grade, shape is a matter of preference rather than quality - but it significantly affects the overall appearance and finger coverage, brilliance and sparkle pattern, ring style compatibility, personal symbolism, and style expression.

Whether you prefer understated elegance or bold design, the right diamond shape enhances both the beauty of the stone and the meaning behind it.

Some of the popular antique diamond shapes include:

Round Brilliant Cut	Round Rose Cut
Hexagon Cut	Emerald Cut
Princess Square	Marquise Cut
Asscher cut diamond	Trillion Cut diamond
Kite Cut	Shield Cut
Pear Cut	Oval Cut
Cushion Cut

The well-known antique diamond cuts that have gained a lot of popularity are listed below:

Round Brilliant: The Timeless Classic

Round brilliants are best for maximum sparkle and traditional grandeur. The round brilliant is the most popular and recognizable diamond shape in the world. Designed with 58 facets, it is designed to reflect maximum light, providing unparalleled brilliance and fire.

Choose a round brilliant because it offers excellent sparkle and light performance. It works with almost any ring setting. The round brilliant is a timeless charm that never goes out of style.

Round diamonds generally command a higher price per carat due to demand and the deterioration of rougher diamonds - but for many, the brilliance is worth it.

Oval: Elegant and Elongated

Classic brilliance is the best for a modern look. Oval diamonds offer the same sparkle as round diamonds but with a more elongated silhouette. This shape creates the illusion of long, slender fingers, making them appear larger than their carat weight.

Why choose oval?

• Excellent sparkle with soft contours
• Elegant, flattering shape
• Ideal for minimalist and vintage-inspired designs

Considerations

Some oval diamonds can exhibit a "bow-tie" shadow effect, which can be minimized by choosing a well-cut stone.

Princess: Modern and Bold

Best for contemporary style with strong sparkle. The princess cut is the most popular square-shaped diamond. Known for its sharp corners and vibrant brilliance, it blends modern design with exceptional light return.

Choose a princess for a clean, geometric look. Has high brilliance for a non-round shape. Princess diamonds are excellent value compared to round diamonds.

Considerations about the princess cut are that the sharp corners require protective settings to prevent chipping.

Cushion: Soft and Romantic

Best for vintage lovers and romantic souls. Cushion-shaped diamonds have rounded corners and a pillow-like profile. Their appeal lies in the balance of brilliance and softness, often associated with antique-style jewelry.

Choose a cushion because it has a romantic and timeless feel. It looks beautiful in halo and vintage settings, and is easily available in modern or antique facet styles. Cushion diamonds vary widely in brilliance depending on the facet pattern.

Emerald: Understated Luxury

Emeralds are known for their sophisticated and minimalist style. Emerald-cut diamonds are known for their rectangular shape and step-cut facets. Rather than sparkle, they emphasize clarity, symmetry, and grandeur.

Choose emeralds for their clean, architectural beauty. Emeralds create a “hall of mirrors” effect. They are perfect for clean, modern designs. Emerald inclusions are more visible, so a high clarity is recommended.

Radiant: Sparkle with Structure

Radiant cuts with sharp lines have a glamorous shine. Radiant diamonds combine the brilliance of a round cut with the shape of an emerald cut. With well-defined corners and faceted pavilions, they offer intense brilliance.

Choose radiant because it is a stone that offers bold sparkle and strong presence. It offers a versatile shape for modern settings. It hides inclusions well. Radiant diamonds can appear a bit deep, so proportion is important.

Pear: Graceful and Unique

The pear shape is best for artistic and expressive personalities. The pear shape blends round and marquise characteristics, creating a teardrop silhouette. It is elegant, distinctive, and perfect for someone who wants something different.

You may choose a pear because its elongated shape flatters the hand. The pear appears larger per carat, making it look cheaper in value but more expensive in shape. The pear works beautifully in solitaire and halo designs.

Considerations:

Symmetry is important - an uneven pear can look unbalanced.

Marquise: Dramatic and Regal

Marquise is the best diamond for bold statement jewelry. With pointed ends and an elongated body, marquise diamonds maximize surface area and create a dramatic look. Historically favored by royalty, this shape feels both vintage and daring.

Why choose Marquise?

• Makes fingers appear longer
• Offers excellent visual size
• Ideal for unique, custom designs

Considerations

Points require protection, and symmetry is key.

Asscher: Art Deco Elegance

Best for Vintage sophistication and clean geometry. The Asscher cut resembles a square emerald cut with deeply cropped corners and step facets. It’s prized for its depth and architectural beauty.

Escher You can choose for its distinctive Art Deco appeal. Escher emphasizes clarity and precision. Ideal for statement solitaire. Smaller tables mean less shine but more depth.

Heart: Symbol of Romance

Heart shape is great for emotional and expressive wearers. Heart-shaped diamonds are a bold symbol of love and emotion. When well-cut, they are symmetrical and eye-catching.

Choose a heart because of its strong romantic symbolism, the heart shape is unique and meaningful. It is perfect for personalized or custom designs. Cut quality is essential for a balanced, elegant look.

4. Ethical Values

Lab-grown diamonds allow you to explore all shapes with a smaller environmental footprint and greater value.
