What Is a Radiant Cut Moissanite? Radiant vs Emerald vs Cushion Explained

24/09/2026 | Rodio Ice&Co

Quick Answer: A radiant cut moissanite is a rectangular or square stone with trimmed corners and brilliant facets. It has the elegant outline of an emerald cut but the intense sparkle of a round brilliant. It is one of the most fiery shapes you can choose, and the trimmed corners make it durable for everyday wear.

Key Takeaways

  • Radiant = emerald-cut outline + brilliant-cut sparkle.
  • Moissanite's high dispersion makes radiants exceptionally fiery.
  • Trimmed corners help prevent chipping.

Emerald Rectangle, cut corners Step Elegant flashes of light
Cushion Square or rectangle, rounded corners Brilliant Soft and romantic

Why Radiant Cuts Look So Lively

A radiant cut has dozens of brilliant facets in the crown and pavilion, which break light into many small, bright flashes. Combined with moissanite's strong fire, the result is a stone that seems to glow with color from every angle.

Choosing Your Proportions

  • Square radiant (about 1.00 to 1.05): bold and modern.
  • Classic rectangle (about 1.20 to 1.35): balanced and elegant.
  • Elongated (1.35 and above): slimming and dramatic, very popular right now.

Best Settings for a Radiant

  • Four-prong solitaire: clean and striking.
  • Hidden halo: sparkle from the side.
  • Three-stone with trapezoid or pear side stones: luxurious and wide.
  • Pave band: adds extra shimmer.
