Introduction
The Radiant Cut Diamond combines the brilliance of a round diamond with the clean, elegant shape of an emerald cut. With its trimmed corners and sparkling facets, it’s a favorite for those who love both fire and symmetry. The radiant cut’s unique design maximizes light reflection, giving it an eye-catching glow that stands out in any setting.
History of the Radiant Cut Diamond
The radiant cut was introduced in 1977 by master cutter Henry Grossbard. His goal was to merge the glamour of step cuts and the brilliance of round cuts. The result was a rectangular or square diamond with 70 facets, offering unmatched sparkle and symmetry. Since then, radiant cut diamonds have become a popular choice for modern engagement rings.
