Why choose a radiant cut diamond?

The radiant cut trims the corners of a rectangular or square outline and adds brilliant faceting, combining the clean lines of an emerald cut with the sparkle of a round brilliant. It is durable thanks to its cropped corners and intensifies colour beautifully.

How to choose a radiant lab-grown diamond

Shape. Square radiants have a length-to-width ratio close to 1.00; rectangular radiants are around 1.20 to 1.40.

Colour and clarity. D to G gives a bright white look; VS1 and VS2 clarity are eye-clean thanks to the radiant's brilliant faceting.
