Its symmetrical shape is beloved for its versatility, pairing beautifully with everything from classic solitaires to intricate halo settings.
Cushion: Soft, Romantic Glow
The cushion shape, with its softly rounded corners and larger facets, offers a unique blend of vintage allure and modern sophistication. Known for its pillow-like shape and romantic glow, this design showcases a diamond’s clarity and enhances its fire, making it a favorite for those who cherish timeless beauty with a touch of whimsy.
Pear: Graceful and Refined
The pear shape features a rounded end that tapers to a single point, creating a teardrop silhouette that naturally elongates the finger. It blends softness with elegance, offering a timeless look that’s both delicate and striking.

Oval: Elegant and Eye-Catching
Oval-shaped diamonds combine the brilliance of a round diamond with a lengthening silhouette that flatters the finger. Their elongated shape offers a soft, elegant presence that feels timeless but modern.
Emerald: Refined and Architectural
With its hall-of-mirrors effect and sleek step cuts, the emerald shape is loved for its clean lines and refined sparkle.
Radiant: Bold and Brilliant
Radiant-shaped diamonds offer the fire of a round brilliant with the structure of a rectangular or square outline.

The Asscher diamond shape evokes the elegance of the Art Deco era. With deep step cuts and a square silhouette, it draws the eye inward like a hall of mirrors.

How Diamond Shape Influences Style
While diamond shape is often the first thing that catches your eye, it’s also one of the most powerful ways to express your style. Understanding how each shape pairs with different settings and styles helps you design a piece that’s as unique as you are.
Pairing Shape with Ring Settings
The right setting can elevate your diamond’s shape, highlighting its best features and reflecting your personal style. A round brilliant, for example, looks stunning in a classic solitaire setting, where its symmetrical sparkle truly shines. For a more contemporary look, an emerald diamond pairs beautifully with a sleek, modern band, adding architectural intrigue to your ring.
