Radiant Cut
A rectangular or square brilliant with cropped corners that combines the elegance of the emerald cut with brilliant-cut sparkle.
Definition
The radiant cut bridges the gap between step cuts and brilliant cuts. It has the rectangular shape and cropped corners of an emerald cut, but its 70-facet brilliant pavilion produces the fire and sparkle associated with round brilliants. Created in 1977, it is the first truly rectangular brilliant-cut diamond.
Why It Matters for Ring Design
Radiants hide inclusions and color better than emerald cuts, making them a more forgiving choice. They pair beautifully with baguette side stones. Square radiants are often confused with cushion cuts — the key difference is the straight, not curved, sides.
