Princess Cut vs Cushion Cut: Which Is Better?

Corners are what set these two shapes apart. A princess cut is square, sometimes slightly rectangular, with sharp corners that come to a crisp point, giving it a modern, geometric look. A cushion cut shares that square-to-rectangular base but softens every corner into a curve, and its facets throw a warmer, more vintage-inspired glow. Neither is objectively the better choice; it comes down to how you feel about corners, era, and how the ring needs to hold up to daily wear. At Diamondrensu, both shapes come in lab grown diamond and moissanite, giving you the freedom to choose the shape and stone type that suit you best.

Princess Cut vs Cushion Cut: Quick Comparison

At a glance, here's how princess and cushion cut compare.

• Shape: A princess cut is your classic square or rectangle, featuring four sharp corners that meet at clean 90-degree angles. The cushion cut takes those same four sides but softens them into gentle, rounded curves, giving the stone a noticeably fuller, pillowy outline.
  
• Era: The cushion cut has serious history behind it. This is a design that traces back to the 1700s and still holds the title of the oldest diamond cut in widespread use today. The princess cut, by contrast, is a modern invention, arriving on the scene in the 1960s and 70s when jewelers began experimenting with fresh silhouettes.
• Brilliance style: When it comes to sparkle, the two cuts speak entirely different languages. A princess cut delivers bold, uniform flashes of light, each one crisp and disciplined. The cushion cut is more unpredictable in the best way, with some stones throwing wide, dramatic bursts of light while others settle into a softer, almost hazy shimmer known as the crushed ice effect, depending on how the facets are arranged.
• Best for: Go princess if you want a look that's clean, geometric, and contemporary; go cushion if warmth and vintage romance matter more to you.
  

Meet the Two Shapes

What is a Princess Cut Diamond?

The clearest way to spot a princess cut is by its corners: four sharp, unrounded right angles that give the stone an inverted-pyramid profile when viewed from the side, with the widest point at the top of the setting. Jewelers reportedly developed it in the 1960s and 70s to give a square cut that could rival round-diamond brilliance without sacrificing rough carat weight.

What is a Cushion Cut Diamond?

A cushion cut is easiest to identify by its rounded corners and slightly curved sides, which give the outline a soft, pillow-like shape, and the name comes from exactly that resemblance. It is the oldest diamond cut still in wide use, tracing back to the 1700s, when cutters shaped diamonds by hand and believed rounded corners helped protect the stone from chipping during faceting. Its centuries-long history and the way it has been reinterpreted across eras of jewelry design, are a big part of why it reads as vintage today, even in a brand-new ring.

Princess Cut vs Cushion Cut: Key Differences

Shape and Corners

The single biggest visual difference between these two cuts is the corners. A princess cut keeps its corners sharp and pointed, giving it a bold, architectural outline that reads as modern and geometric. A cushion cut softens those same corners into a gentle curve, which rounds out the whole silhouette and gives the stone a more relaxed, romantic outline. Both shapes can be cut as a true square or elongated into a rectangle, but the corner treatment is what separates them at a glance.

Brilliance and Sparkle Style

Princess cut diamonds are typically faceted in a chevron pattern (V-shaped facets that radiate out from the center), which channels light into bright, evenly distributed flashes across the whole face of the stone. Cushion cut diamonds are cut in two main styles: a classic brilliant facet pattern that produces bold, chunky flashes of light, or a “crushed ice” pattern, made of many small, irregular facets that scatter light into a soft, sparkly haze rather than distinct flashes. Neither style is more brilliant than the other in a strict sense; they simply distribute light differently, so the right one comes down to whether you prefer crisp, defined sparkle or a softer, more diffused glow.

Face-Up Size and Carat Weight

Because a princess cut has more depth relative to its width, it can look slightly smaller face-up than its carat weight suggests, though its sharp corners still read as a full square. A cushion cut, especially in its more square proportions, can also appear a touch smaller than the same carat weight in a round or oval stone. Choosing a more elongated cushion is the simplest way to offset that, since it tends to maximize face-up size most effectively among cushion-cut proportions.

Durability and Corner Protection

Sharp corners tend to be the more vulnerable point on fancy-shape diamonds generally, since they are more exposed to knocks and chipping in daily wear. A princess cut's pointed corners benefit from a protective setting, such as a V-tip prong or bezel, to guard against damage. A cushion cut's rounded corners are inherently more forgiving day-to-day, since there is no sharp point to catch or chip. That durability may be part of why it's remained a practical choice for daily wear.

Princess Cut or Cushion Cut: How to Choose

Choose Princess Cut If…

You're drawn to clean lines, sharp geometry, and a distinctly modern look. Its sharp angles are why solitaire, channel-set, or bezel settings suit it best, since they echo the geometry rather than compete with it. It's also a strong choice if you already lean toward contemporary, minimalist styling elsewhere in your jewelry collection, or if bright, evenly distributed sparkle matters more to you than a softer glow.

Choose Cushion Cut If…

You want a romantic, vintage-inspired ring with a softer overall silhouette. Its rounded outline is why halo and hidden halo settings suit it so well, since the extra ring of sparkle plays up its soft edges rather than sharpening them. It also suits anyone who prefers a warmer, more diffused glow over sharp, geometric flashes, or who wants a shape with real historical weight behind it.

Shop Princess and Cushion Cut Diamonds at Diamondrensu

Both princess and cushion cut diamonds are available at Diamondrensu in two stone types: lab grown diamond and moissanite. And each stone comes with IGI certification, which means its quality is independently verified, so you can buy with confidence. A lab grown diamond is the same as a natural diamond as the former shares the same optical, chemical, and physical properties, since it is also made of crystallized carbon. The difference is origin: labs grow it in a controlled environment rather than mining it from the earth, which typically makes it more affordable at the same carat weight and clarity. Moissanite is a different mineral, silicon carbide rather than carbon. Its exceptionally high refractive index gives it a fiery sparkle, and it typically costs less than either natural or lab grown diamond.

Princess Cut in Lab Grown Diamond and Moissanite

Shoppers who want the princess cut's sharp, modern outline can choose it in lab grown diamond for a more budget-friendly option without giving up any of the shape's crisp brilliance, or in moissanite, which is known for exceptional fire due to its high refractive index and affordable price.

Cushion Cut in Lab Grown Diamond and Moissanite

The cushion cut's soft, vintage-leaning silhouette is also available in both lab grown diamond and moissanite, giving shoppers a similarly romantic look across a range of budgets, whether the priority is a lower price point, a larger stone for the money, or simply choosing a lab-created option over a mined one for ethical reasons.
