Radiant cut engagement rings have become modern masterpieces due to their chic square form and softly trimmed corners. A radiant engagement ring’s square silhouette and sparkling facets render it an unforgettable center stone.
Master diamond cutter Henry Grossbard invented the radiant cut ring in 1977. He aimed to combine the timelessness of a square silhouette with the brilliance and fire of a round cut.
A radiant stone is cut with 70 facets and is available in square and rectangular shapes. In addition, the radiant cut's corners are beveled (rather than sharp), making the diamond more resilient and less likely to crack.
This fancy cut diamond has subsequently become the center stone for many celebrity engagement rings.
Radiant-cut diamonds have princess-cut facets but are often rectangular in shape, similar to an emerald cut. The trimmed or smooth corners of a radiant-cut diamond set it apart from the competition.
When choosing a radiant ring, look for well-centered cullet, parallel sides, and equal-sized corners. Once you've decided on a square or rectangular shape, make sure the proportions are correct. The optimal ratio for rectangular radiant cut engagement rings is 1.25, but any value between 1.20 and 1.30 will do. A ratio of 1.00-1.03 is recommended for a square-shaped radiant cut.
