The radiant cut combines the best of the round cut (its fire) and of the emerald and Asscher cut (its less fiery shape)! This cut was designed to have the most brightness possible.
The radiant cut diamond is often a rectangle (sometimes square) with cropped corners, it’s faceted for fire. It’s also forgiving with imperfections.
For a radiant diamond shape that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.10
