Why choose a cushion cut diamond?

Cushion cuts pair rounded corners with larger facets for a soft, pillow-like outline and a warm, vintage-inspired glow. They are especially good at showing off colour, which is why many of our pink, blue and yellow diamonds are cushion cut.

How to choose a cushion lab-grown diamond

Shape. Square cushions have a length-to-width ratio close to 1.00; elongated cushions are around 1.15 to 1.30.

Colour and clarity. D to G gives a bright white look; VS1 and VS2 clarity are eye-clean.

Shape

Square cushions have a length-to-width ratio of 1.00 to 1.08; elongated cushions are around 1.15 to 1.35.

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.
