Everything You Need to Know About Cushion Cut Diamonds
Quick Summary
Cushion-cut diamonds feature soft, rounded corners and a romantic pillow-like shape. Known for their vintage charm, beautiful fire, and versatility, they offer a softer sparkle than round diamonds while effectively hiding color and inclusions. Their durable design and timeless appeal make them a popular choice for both classic and modern engagement rings.

What Is a Cushion Cut Diamond?
A cushion-cut diamond is distinguished by its square or rectangular shape with softly rounded corners, giving it the appearance of a cushion or pillow. Typically featuring 58 facets, it produces a softer, more romantic sparkle than a round brilliant diamond, with light that appears more dispersed and gentle. Its combination of vintage elegance, noticeable presence, and timeless appeal has made the cushion cut a popular choice for engagement rings and fine jewelry.
History of the Cushion Cut
The cushion cut has a rich history dating back to the 18th century, when diamond cutters developed the Old Mine Cut, one of the earliest diamond-cutting styles. Characterized by its rounded corners and large facets, it became the foundation for the modern cushion cut. Over time, advancements in diamond-cutting techniques led to refined proportions, improved facet arrangements, and enhanced light performance. Today’s cushion-cut diamonds preserve the charm and character of their historic origins while offering the brilliance and beauty expected by modern buyers.
Visual Characteristics: Chunky vs. Crushed Ice
Most cushion-cut diamonds have a length-to-width ratio between 1.00 and 1.05, giving them a nearly square appearance with balanced proportions. When selecting a cushion cut, one of the biggest decisions involves the type of sparkle you prefer: chunky brilliance or crushed-ice shimmer.
Cushion Brilliant
Cushion Brilliant diamonds feature larger, well-defined facets that produce bold, distinct flashes of light. Often referred to as “chunky cushions,” they closely resemble the traditional Old Mine Cut and are prized for their vintage-inspired character and romantic appeal. Their sparkle is broad and dramatic, creating a classic look with plenty of personality.
Cushion Modified Brilliant
Cushion Modified Brilliant diamonds contain a greater number of smaller facets, creating a lively, all-over sparkle effect. Rather than producing large flashes of light, they display a fine, shimmering brilliance often compared to crushed ice. This style is commonly known as a “crushed-ice cushion” and is the most widely available cushion-cut variation today.
Which One Is Better?
Neither style is inherently better than the other—each offers a unique visual experience. Chunky cushions appeal to those who love bold flashes of light and vintage charm, while crushed-ice cushions are favored by buyers who prefer a more intense, glittering sparkle. The best choice ultimately comes down to personal taste, so it’s worth viewing both styles before making a decision.

What Makes Them Great
Timeless Appeal: Cushion cuts have remained popular for more than two centuries, proving their enduring style and versatility. Whether featured in a vintage-inspired halo setting or a sleek modern solitaire, they adapt effortlessly to a wide range of ring designs.
Soft, Romantic Shape: With their gently rounded corners and curved edges, cushion cuts offer a softer and more inviting appearance than sharp, angular diamond shapes. Their signature pillow-like silhouette creates a warm, elegant look that feels both classic and romantic.
Beautiful Brilliance: A well-cut cushion diamond delivers impressive sparkle and light performance. While it may not match the intense brilliance of a round brilliant cut, it often displays exceptional fire, producing vibrant flashes of color that give the diamond a lively and captivating appearance. The result is a sparkle that feels rich, warm, and full of character.
What to Know Before Buying
Sparkle Can Vary Significantly:Cushion-cut diamonds can look very different from one another, even when they share similar measurements. Some display bold, chunky flashes of light, while others feature a finer crushed-ice sparkle. Because of this variation, it’s important to evaluate each stone individually rather than relying solely on specifications.
Smaller Face-Up Size: Due to their deeper proportions and rounded corners, cushion cuts may appear slightly smaller from the top than a round diamond of the same carat weight. If maximizing visual size is a priority, you may want to consider a slightly higher carat weight.
Potential for a Glassy Look: Some poorly cut crushed-ice cushion diamonds can appear flat or glass-like, lacking the depth, fire, and brilliance expected from a high-quality stone. Reviewing detailed images, videos, or light-performance information can help ensure the diamond delivers the sparkle and visual appeal you're looking for.
How to Choose Your Cushion Cut
Unlike Round Brilliant diamonds, cushion cuts do not have a standardized cut grading system, which means their appearance can vary considerably from one stone to another. Understanding a few key factors can help you choose a cushion-cut diamond that delivers exceptional beauty and sparkle.
1. Decide on Your Preferred Sparkle Style
Before focusing on carat weight, color, or clarity, determine the type of sparkle you prefer. Cushion cuts generally fall into two categories:
- Chunky Cushion Brilliants – Feature larger facets that create bold, distinct flashes of light and a more vintage-inspired appearance.
- Crushed-Ice Cushion Brilliants – Contain smaller facets that produce a fine, shimmering sparkle throughout the stone.
Since these styles can look dramatically different, viewing photos and videos of both can help you identify the look that best matches your taste.
2. Select Color With the Setting in Mind
Cushion-cut diamonds tend to reveal color more readily than round diamonds, making color selection an important consideration. For a bright, crisp appearance in platinum, 14k gold, or 18k gold settings, many buyers prefer diamonds in the F color range or higher. Pairing a high color grade with excellent clarity can help maximize brilliance and maintain a clean, vibrant appearance across different metal types. The right balance of color and clarity will ensure your cushion-cut diamond looks beautiful in any setting.
