Cushion Cut Diamond

A cushion cut diamond serves as the ultimate symbol of romantic elegance. This classic shape blends a structured square silhouette with gently rounded corners to create a soft and inviting presence. Unlike brilliant cuts that prioritize sharp white sparkle, a cushion diamond relies on broad facets to deliver deep pools of colored fire. We curate a thoughtful selection of these captivating stones for those who seek a warmer and more enduring glow.

Our collection highlights the rich history of this shape by offering both refined modern designs and authentic old mine proportions. A true antique inspired diamond features a steep crown and a distinctive open culet to capture ambient light beautifully. We secure these extraordinary stones in tailored bezels and delicate pavé settings to protect their soft curves. Every Elora creation celebrates timeless devotion and sophisticated vintage charm.

Diamond Cut Cushion

The Structure and Value of Cushion Cut Diamonds

A cushion cut diamond merges a square profile with softly rounded corners to offer a highly efficient use of rough material. Diamond cutters originally developed this shape to retain significantly more of the rough stone compared to a standard round brilliant. This higher material yield translates directly to a more accessible price point per carat, allowing you to allocate your budget toward a larger physical size rather than paying for wasted material. The underlying geometry relies on a deep pavilion and a high crown, an architectural combination that acts like a prism to capture light and break it into distinct flashes of colored fire.

Understanding the Optical Variations

The visual impact of a cushion cut depends heavily on its specific facet pattern, which we categorize into three distinct optical personalities. A Standard Cushion Brilliant features broader facets designed to produce large, bold flashes of light and high visual contrast. Conversely, a Modified Cushion utilizes an extra row of facets on the pavilion to create a "crushed ice" effect, delivering rapid, pinpoint scintillation.

For those drawn to historical romance, our collection of Old Mine Cut Cushions offers a soulful alternative. These diamonds honor the original 18th-century hand-cut aesthetic, characterized by a higher crown, a smaller table, and an open culet. Unlike the sharp brilliance of modern cuts, the Old Mine Cut is celebrated for its "inner glow" and "chunky" fire, reflecting light in soft, romantic ribbons that are particularly captivating in candlelight. Whether you prefer the precision of modern engineering or the antique character of a heritage cut, we evaluate every stone to ensure it delivers intense, intentional light return.

Managing Color and Clarity

This specific shape requires a highly strategic approach to color and clarity grading. Because the deep pavilion naturally retains and concentrates the inherent body color of the diamond, it does not mask slight tints as effectively as a round stone. You must prioritize a higher color grade to guarantee a purely white center stone. Conversely, the complex faceting proves incredibly forgiving regarding clarity. The intense light dispersion easily hides minor internal inclusions, an optical advantage that allows you to lower your clarity requirement safely and maximize your total carat weight.

Anchoring Your Ring Design

A cushion diamond provides a versatile and robust core for custom ring designs, though its rounded corners require specific structural support to prevent chipping during daily wear. We carefully engineer our metalwork to protect these vulnerable edges without obstructing light from entering the lower facets. For instance, the Hazel Cushion Bezel wraps the perimeter entirely in solid gold to ensure maximum physical security. If you prefer a multi stone layout, the soft geometry pairs effortlessly with elongated shapes as seen in the Idra Toi et Moi Ring. Ultimately, this rigorous design process results in a piece of jewelry engineered for both exceptional beauty and long term structural safety.

Frequently asked questions

What is a cushion cut diamond?

A cushion cut is a square or slightly rectangular diamond with rounded corners.

It combines a softer outline with a facet pattern that can vary quite a bit in appearance, which is why no two cushion diamonds look exactly the same.

What is an antique cushion cut?

It usually refers to old mine cut or vintage-style cushions, featuring larger facets, a softer, more romantic sparkle, and often an open culet that appears as a small round or slightly elongated shape at the center.

What’s the difference between modern cushion cuts and antique cushion cuts?

The difference comes down to how the diamond is faceted.

Modern cushion cuts often feature a “crushed ice” look, with many small reflections that create a bright, lively sparkle. Antique cushion cuts, like old mine cuts, have larger, more defined facets and often include an open culet, giving a softer, more romantic glow.

Neither is better. It depends on whether you prefer a more brilliant, lively sparkle or a more classic, structured look.

How to choose an antique cushion cut diamond?

Focus on the faceting pattern, overall shape, and culet. Look for balanced proportions, pleasing symmetry, and an open culet that adds character without being distracting.

In addition to classic white diamonds, you can also consider warm tones like champagne for a more vintage feel. At Elora, we can custom cut antique cushion diamonds in both white and champagne tones based on your preference.

Why are cushion cut diamonds often associated with vintage styles?

Cushion cuts trace back to older cutting styles from the 19th century, which is why they’re often linked to antique and vintage-inspired jewelry.

Their soft corners and broader facets give them a slightly old-world feel, especially in designs that lean toward antique or heirloom aesthetics.

Which cushion cut sparkles more?

They sparkle differently rather than more or less.

Modern brilliant cushions tend to give off constant shimmer, while antique cushions produce slower, more noticeable flashes of light. It’s more about style than intensity.

What ratio looks best for a cushion cut diamond?

Cushion cuts come in two main types: square and elongated. 

Most square cushions fall between 1.00–1.10, while elongated cushions are usually around 1.20–1.40. Square cushions feel more classic, while elongated ones look more modern and flatter the finger.

Do cushion diamonds look big for their carat weight?

Cushion diamonds tend to have a fuller, softer outline, which can make them feel visually substantial.However, they usually don’t appear as large as elongated shapes like oval or marquise, since more weight is often carried in the depth rather than spread across the surface.

Do cushion cut diamonds hide inclusions well?

In many cases, yes.

Especially in crushed ice styles, the busy facet pattern can help mask small inclusions better than step-cut diamonds. However, larger or darker inclusions can still be visible depending on placement.

Do cushion diamonds show color more easily?

They can show a bit more warmth than round diamonds, especially in larger stones.

If you prefer a brighter, whiter look, choosing a slightly higher color grade can help, but some people actually like the softer, warmer tone cushion cuts can have.

Does a cushion cut work with different ring styles?

Yes. The rounded corners make it easy to pair with a wide range of settings.

It works well in minimalist solitaire designs, as well as more detailed styles like halo or pavé bands, making it one of the more adaptable shapes.

What should I focus on when choosing a cushion diamond?

Focus on how it looks rather than just the specs.

Pay attention to the facet style (crushed ice vs chunky), overall shape, and how the diamond reflects light. Cushion cuts are one of the most visual shapes, so seeing the actual stone matters more than numbers.

Are cushion cut diamonds suitable for everyday wear?

Yes.

Their rounded corners make them less prone to chipping than pointed shapes, and with a well-made setting, they hold up well for daily wear.
