Choosing Your Diamond's Personality: The Sparkling Showdown Between Round Brilliant and Cushion Brilliant Faceting.

Sparkle, Scintillation, and a Dash of Geometry

So, you’ve decided it’s time for some serious sparkle—congratulations! Whether you’re dreaming of a show-stopping engagement ring or a magnificent piece of diamond jewelry, one of the first and most thrilling choices you’ll make is the shape of your center stone. But let’s be real, when you start looking, the world of diamonds can feel a bit like high school geometry class got fancy. Today, we’re putting two of the most popular and personality-packed cuts in the spotlight: the timelessly classic Round Brilliant and the romantically soft Cushion Brilliant. Think of it as choosing between a perfectly executed power ballad and a soulful, indie love song—both are amazing, but they create a completely different vibe on your hand.

Meet the Contender: The Round Brilliant Cut

The Round Brilliant is the undisputed prom king of the diamond world. Developed over centuries to maximize light return, its 57 or 58 precisely angled facets are a masterclass in optical engineering. The goal? Unmatched fire, brilliance, and scintillation. That’s gemologist-speak for “it throws rainbows and sparkles like a disco ball under a spotlight.” If you’re looking for a diamond whose primary mission is to be seen from space (or at least across a dimly lit restaurant), this is your cut. It’s a universally flattering shape that works in virtually every setting, from a sleek solitaire to an intricate halo. You&ll find this iconic cut featured in stunning pieces from our Gumuchian - Bridal and Oscar Heyman collections.

Meet the Charmer: The Cushion Brilliant Cut

Now, let’s turn to the Cushion Brilliant, the dreamy poet of the bunch. With its soft, rounded corners and larger, chunky facets (often in a “crushed ice” or “antique” style), the cushion cut offers a more romantic, luminous glow. Its sparkle is less “fireworks display” and more “candlelit shimmer.” This cut has a vintage soul but a modern appeal, often appearing larger face-up than a round of the same carat weight. It’s for the person who loves a blend of classic elegance and unique character—think heirloom vibes with a contemporary twist. Designers like Charles Krypell and Pasquale Bruni often use cushion cuts to create pieces with unforgettable, soft-focused glamour.

The Aesthetic Face-Off: How to Choose Your Sparkle Soulmate

Choosing between these two isn’t just about looks; it’s about which one aligns with your personal sparkle signature. Let’s break it down.

For Maximum, Unapologetic Sparkle: If your motto is “more is more” and you want the ultimate in brilliance, the Round Brilliant is your clear winner. Its predictable pattern of light return means it performs spectacularly in almost any light. It’s the perfect choice for a classic tennis bracelet or a pair of dazzling diamond stud earrings.

For Romantic, Soft-Focus Glamour: If you’re drawn to a gentler, more diffuse light and love a touch of vintage charm, the Cushion Brilliant will steal your heart. Its unique faceting pattern can mask inclusions slightly better than a round, offering great value. It looks phenomenal in a Toi et Moi ring or as a centerpiece in a cluster pendant.

Considering Style & Setting: Round brillants are versatile chameleons. They shine in everything from a minimalist bezel to an elaborate three-stone setting. Cushion cuts often sing in settings that complement their soft shape—think ornate halos, vintage-inspired filigree, or elegant cushion halo rings. They also pair beautifully with colored gemstone side stones, like sapphires or rubies.

Beyond the Basics: Modern Twists and Brilliant Advice

The fun doesn’t stop with the traditional! Modern cutters are playing with both shapes. You can find “hybrid” cushion cuts that blend the chunky facet pattern of an antique cushion with the precision of a modern round for incredible sparkle. And for the round, fancy cuts like the “round hearts and arrows” offer an even more precise, symmetrical pattern for the ultimate sparkle connoisseur.

Our best piece of advice? Don’t just read about it—come see it! The true character of a diamond reveals itself in person, under different lights. A cushion cut might look like a puddle of light in one setting and a glittering marvel in another. The same goes for a round. That’s why at Robinson’s, we encourage you to visit and try them on. See how a brilliant round looks on your hand next to a plush cushion. Which one makes you smile wider? Which one feels more “you”?
