Home » Radiant Cutting Guide
In the world of high jewelry, there are shapes that follow the rules and shapes that rewrite them. The radiant cutting belongs to the second category. For decades, the choice has been stark: the austere, crystalline geometry of the emerald cut or the fiery sparkle of the round brilliant cut.
Then, in the 1970s, came an innovation: the radiant cut.
It is a technical masterpiece, an ingenious hybrid that captures the best of two worlds. It possesses the rectangular (or square) shape and clean lines of the emerald, but hides within it the complex facet of the brilliant.
The result? A diamond that offers explosive brilliance and a “fire” you would never expect from a geometric shape. It is the choice for the woman who loves structured elegance, but doesn't want to give up a hypnotic sparkle.
The radiant cut was created in 1977 by Henry Grossbard, a master cutter who took 33 years to perfect his vision. His goal was revolutionary: to create a stepped cut (like an emerald) that could, however, shine with the same intensity as a brilliant cut.
He achieved this by radically altering the pavilion (the underside of the stone), applying a complex pattern of triangular and “diamond” facets typical of brilliant cuts. With its 70 facets, the radiant is an optical machine designed to maximize light return.

Understanding the radiant means comparing it to its more famous “neighbors.” The choice between these cuts defines a ring's personality.
This is the most common comparison. Both offer a sophisticated rectangular silhouette.
The Emerald: It is a step cutting (step-cut). Its long, linear facets create a “hall of mirrors” (hall of mirrors). It celebrates the clarity and purity of the gem, offering elegant flashes of light.
The Radiant: It is a modified brilliant cut. Its triangle and kite facets create a chaotic and vibrant sparkle. It celebrates the brilliance and fire.
If you are looking for understated, crystalline elegance, choose Emerald. If you desire a rectangular shape that bursts with light, choose the Radiant.
