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.

How to choose a radiant diamond

Why choose a radiant?

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. Its cropped corners make it hard-wearing, and it intensifies colour beautifully.

Shape

Square radiants have a length-to-width ratio close to 1.00; rectangular radiants are around 1.15 to 1.50.

Colour and clarity

D to G looks white once set. VS2 and better look clean to the eye, and almost all of ours are VS2 or better. Every stone has a 360° video on its page, so you can see how clean it looks.
