Radiant Cut Diamond Guide
Rectangular, brilliant and fire-rich — here is why the radiant cut is one of the most requested diamond shapes and how to buy it well.
What is a radiant cut?
The radiant cut is a rectangular or square diamond with cut corners and a brilliant-style facet pattern. It was designed to combine the sparkle of a round brilliant with the elegance of an emerald shape. Because it is so brilliant, it is a favourite for halo and three-stone settings.

What to check before buying
Ask for VS2 or better clarity — the radiant table is open and shows inclusions. A length-to-width ratio of 1.15–1.35 reads best on the hand. For a custom radiant ring, message our factory directly.
