Radiant Cut Diamond Guide: History, Price, Styling Tips
The radiant cut diamond is often described as the best of both worlds: it fuses the fiery brilliance of a round cut with the clean, angular silhouette of an emerald cut. First introduced in the late 1970s, this modern hybrid has earned a loyal following for its impressive sparkle, rectangular (or square) shape, and beveled corners that provide durability and elegance in equal measure.
Whether you're looking for a bold engagement ring or a versatile everyday piece, the radiant cut deserves your serious consideration.
1. What Is a Radiant Cut Diamond?
Known for its dazzling brilliance and modern appeal, the radiant cut diamond combines the elegance of emerald cuts with the fire of round brilliants. It features 70 facets, allowing it to reflect light from multiple angles—creating a vibrant, "crushed ice" sparkle that sets it apart from other rectangular cuts.
Unlike the step-cut facets seen in emerald or Asscher diamonds, radiant cuts use brilliant-cut facets throughout, maximizing light performance and internal fire.
Key Features of the Radiant Cut:
Faceting Style: Brilliant-cut facets across the entire surface for maximum sparkle.
Number of Facets: Typically 70, contributing to a dynamic, multidirectional light return.
Sparkle Effect: Known for a “crushed ice” appearance—more scintillating than step-cut shapes.
Versatility in Shape:
Radiant (Rectangular): Elongated and finger-flattering, ideal for those who love a sleek, modern silhouette.
Radiant Square: More symmetrical and compact, with a shape closer to a cushion cut—perfect for balanced, bold looks.
Personal Fit: Choice often depends on finger shape and style preference, as both versions share the same faceting brilliance.

2. A Brief History of the Radiant Cut
Invented in 1977 by master cutter Henry Grossbard, the radiant cut was revolutionary for its time. Prior to its arrival, no rectangular diamond had the sparkle of a brilliant cut. Grossbard’s goal was to combine the brilliance of the round cut with the sophisticated geometry of step cuts, creating something entirely new.
Since then, the radiant cut has evolved with refinements in facet proportions and length-to-width ratios. It has also become a foundation for many custom hybrid cuts, including radiant cushions and radiant ovals.
Notably, radiant cuts rose in popularity in the early 2000s thanks to celebrity engagement rings, and they remain a favorite for those seeking a unique yet timeless look.
3. Radiant Diamond Prices: Natural vs. Lab-Grown
Radiant cut diamonds are generally more affordable than round brilliant diamonds but slightly pricier than emerald or cushion cuts due to their brilliance and cutting complexity.
According to StoneAlgo, as of July 2025:
1-carat natural radiant cut: ~$4,500–$6,000 (VS1 clarity, G-H color)
1-carat lab-grown radiant cut: ~$750–$1,200 for similar specs
2-carat natural radiant cut: ~$10,000–$14,000
2-carat lab-grown: ~$1,800–$2,500
Compared to cushion or emerald cuts, radiant diamonds tend to retain more carat weight after cutting, making them appear slightly smaller face-up, but with significantly more sparkle per millimeter.
Pro Tip: Choose a lab-grown radiant if you want maximum size and sparkle at a lower price. They offer excellent brilliance and are virtually indistinguishable to the naked eye.
4. Style & Setting Recommendations
Radiant cut diamonds are extremely versatile and shine in both minimalist and elaborate settings.
Solitaire or bezel: Emphasizes the clean, modern angles of the cut.
Halo setting: Adds extra sparkle, especially for smaller stones.
Three-stone rings: Pair beautifully with trapezoid or tapered baguette side stones for a luxe Art Deco feel.
East-West setting: Lays the radiant cut horizontally for a fashion-forward twist.
Yellow gold or rose gold bands: Provide warmth that contrasts with the sharp brilliance of the cut.
Radiant cuts are also an excellent choice for pendants and earrings, where their symmetrical brilliance stands out from a distance.
5. Outfit & Styling Tips
Radiant cut diamonds are perfect for powerful, confident styles. Their shape conveys strength, while the brilliance adds flair.
Formal wear: The radiant cut complements sharp silhouettes like tailored suits, blazers, and cocktail dresses.
Casual elegance: Pair a radiant pendant or ring with neutral-toned outfits to let the sparkle speak for itself.
Bold contrasts: The rectangular brilliance contrasts beautifully with soft fabrics like silk or velvet.
Stacking-friendly: Their flat sides allow radiant-cut rings to stack neatly with wedding bands or eternity rings.
Whether you dress up or down, the radiant cut remains a statement piece that doesn’t scream for attention—it glows with quiet authority.

I ordered this as an anniversary gift for my wife, and I’m so glad I did. The engraving I requested came out perfectly—clear, elegant, and exactly how I imagined it. But what really blew her away was the packaging; it’s this beautiful velvet box with a little ribbon, making the whole unboxing experience feel like opening something truly special. That reaction alone makes this purchase the best decision I’ve made in a while. ?

I was worried that such a detailed ring might be clunky or catch on things, but it's not at all! The profile is designed so well. It sits perfectly on my finger, and the U-shaped micro-pave on the band is so smooth. The security of the six-prong setting gives me great peace of mind. The gray presentation box it came in was also super elegant and made the proposal feel even more special. Flawless experience from purchase to unboxing.

I am absolutely stunned by my ring. My fiancé did an incredible job choosing it. The description said 'sculpted halo' and that is exactly what it is—it's like a tiny piece of wearable art. The way the light catches the double bright diamonds is insane; it sparkles from every single angle, even in low light. I can't stop staring at the little heart-shaped arches underneath; it's such a romantic and hidden detail. It's so much more unique than anything I've seen in a typical jewelry store. I feel like a modern-day princess.
Wore it out for coffee and three people asked where I got ittttt. Sorrrry, this one’s my little secret treasureeeee. So obsessed ?
