In this article, we’ll delve into what makes this cut special, share expert insights, and showcase 15 glowing reviews that underscore its radiant diamond beauty, inspiring brides-to-be and jewelry enthusiasts alike.
What Makes the Radiant Cut Diamond Special?
Invented in 1977 by master cutter Henry Grossbard, the radiant cut diamond revolutionized square and rectangular shapes by combining the step-cut outline of an emerald with the brilliant faceting of a round. This hybrid design results in a stone with 70 facets—more than the standard round brilliant’s 58—delivering intense fire, scintillation, and a “crushed ice” appearance that hides inclusions effectively. Typically rectangular or square with beveled corners, it offers versatility in length-to-width ratios from 1.00-1.05 for squares to 1.15-1.35 for elongated forms, flattering various hand shapes.
Key features include exceptional durability against chipping, thanks to those trimmed corners, and a larger face-up size per carat, making it appear bigger than equivalents. Compared to rounds, radiants provide similar sparkle at a lower cost; versus emeralds, they boast more brilliance; against princess cuts, they’re safer with softer edges; and to cushions, they offer straighter lines for a bolder look. This makes it one of the best diamond shapes for timeless diamond cuts that balance affordability, sparkle, and style.
