Cushion-Cut Diamonds

Cushion Cut Diamond Engagement Ring

Among the many diamond shapes available today, the cushion cut remains one of the most enduring. Recognisable by its soft, rounded corners and balanced proportions, this cut sits perfectly between classic and contemporary — offering both brilliance and character.

For those seeking a diamond that feels elegant yet distinctive, the cushion cut continues to be one of the most compelling choices in fine jewellery.

What Is a Cushion-Cut Diamond?

A cushion-cut diamond is defined by its square or rectangular shape with gently curved edges, resembling a pillow — hence the name “cushion.”

This cut combines:

• The soft outline of antique diamonds

• The brilliance of modern faceting

• A versatile silhouette that suits a wide range of settings

Available in both square and elongated proportions, cushion cuts can be tailored to suit personal style — from classic to more directional designs.

A Unique Kind of Brilliance

Unlike round diamonds, which produce sharp, high-intensity sparkle, cushion cuts offer a slightly different visual experience.

Their larger facets create:

• Broader flashes of light

• A softer, more romantic glow

• Depth and dimension within the stone

This makes cushion-cut diamonds particularly appealing for those who prefer subtle brilliance over high sparkle intensity.

Shape and Proportion: Defining the Look

The personality of a cushion-cut diamond is shaped by its proportions:

• Square cushion – balanced, classic, and timeless

• Elongated cushion – more modern, offering greater finger coverage

Even small differences in proportion can significantly change how the diamond looks and feels when worn.

What to Look For in a Cushion-Cut Diamond

When selecting a cushion-cut diamond, traditional grading still matters — but visual appeal is key.

Cut & Faceting

Cushion cuts vary widely in facet structure. Some are designed for maximum brilliance, while others emphasise depth and pattern.

Colour

Cushion cuts can show warmth slightly more than round diamonds, making colour choice important depending on your preference.

Clarity

Thanks to their facet structure, inclusions may be more visible than in brilliant cuts, so eye-clean stones are ideal.

Carat Weight

Cushion cuts carry weight slightly deeper than other shapes, meaning they may appear a touch smaller face-up — but offer beautiful depth.

Setting Styles That Elevate Cushion Diamonds

Cushion-cut diamonds are incredibly versatile and adapt seamlessly to different design styles:

• Solitaire settings – clean, refined, and timeless

• Halo designs – enhance size and brilliance

• Three-stone rings – add balance and dimension

• Bezel settings – modern and protective

Each setting highlights a different aspect of the diamond — whether it’s its shape, size, or light performance.

Why Cushion Cuts Remain Relevant

The appeal of the cushion cut lies in its balance. It is neither overly traditional nor overtly modern. It offers softness without losing presence, and brilliance without appearing overly engineered.

As jewellery trends move toward individuality and longevity, cushion-cut diamonds continue to resonate with those who value timeless design with subtle distinction.
