Why We Love Radiant Cut Diamonds

Radiant diamonds dazzle with their unique blend of brilliance and versatility. Featuring trimmed corners and a rectangular or square shape, these diamonds emit a stunning sparkle that captures attention from every angle.

The Best of Both Worlds

Radiant cut diamonds combine the elegant outline of emerald cuts with the brilliant sparkle of round diamonds. Created in 1977, this hybrid cut features 70 facets that deliver exceptional fire and brilliance while the trimmed corners provide durability and a distinctive geometric shape. Radiant cuts offer the perfect balance of sophistication and sparkle.

Why Choose Radiant Cut Diamonds?

Brilliant Sparkle
With 70 facets, radiant cuts deliver exceptional brilliance and fire—more sparkle than emerald or Asscher cuts while maintaining an elegant rectangular or square shape.

Versatile Shape
Available in both rectangular and square proportions, radiant cuts work beautifully in any setting style from classic to contemporary.

Durable Design
The trimmed corners make radiant cuts more durable than princess cuts (which have sharp corners) while maintaining a geometric, modern aesthetic.

Hides Inclusions
The brilliant facet pattern helps mask minor inclusions better than step cuts, offering more flexibility in clarity grades.

Radiant Cut Characteristics

Shape
Rectangular or square with trimmed (beveled) corners. The trimmed corners distinguish radiant cuts from emerald and princess cuts.

Facet Pattern
70 facets total—brilliant-cut facets on both crown and pavilion create exceptional sparkle. Combines the cutting style of round brilliants with the outline of emerald cuts.

Length-to-Width Ratio
- 1.00-1.05: Square radiant
- 1.15-1.30: Slightly rectangular, balanced
- 1.30-1.50: Elongated rectangular, finger-flattering
Personal preference determines ideal ratio.

Radiant Cut Quality Factors

Cut Quality
Unlike round diamonds, radiant cuts don't have standardized GIA cut grading. Look for:

  • Excellent or very good symmetry
  • Excellent or very good polish
  • Well-proportioned depth and table percentages
  • Even light return across the stone

Color
Radiant cuts can show color slightly more than round diamonds. Consider G-H color or higher for white gold/platinum settings. The brilliant facets help disperse color better than step cuts.

Clarity
VS2-SI1 clarity works well for radiant cuts. The brilliant facets help hide minor inclusions better than emerald or Asscher cuts.

Rectangular vs. Square
- Rectangular radiants: More finger-flattering, appear larger
- Square radiants: More distinctive, alternative to princess cuts

Radiant Cut History

The radiant cut was created in 1977 by Henry Grossbard, who wanted to combine the elegance of emerald cuts with the brilliance of round diamonds. It was the first rectangular cut to feature a complete brilliant-cut facet pattern on both crown and pavilion.

Radiant cuts gained popularity in the 2000s as brides sought alternatives to princess cuts with more durability and sparkle.
