Henry Grossbard introduced the first “Radiant Cut” in 1977. His aim was to capture the brilliance and lustre of the round brilliant cut, whilst combining the elegance of the emerald cut.
The radiant cut received a patent; however, as its popularity soared, so did the copy-cats and within five years, the princess cut was born.
The main difference between the radiant cut and the princess cut is that the princess has pointed corners and is always square, whereas the radiant cut has truncated corners and can be either square or rectangle in shape.
Just like the emerald cut, the radiant cut has truncated corners, but rather than long, parallel facets, the radiant cut has triangular and kite shape facets similar to the round brilliant cut. The original radiant cut had 70 facets: a table, 25 on the crown, 8 on the girdle and 36 on the pavilion.
