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.

Frequently asked questions

Can I see these diamonds in your London store?

Our London store displays finished jewellery and a smaller selection of gemstones. Our loose diamonds are held at our workshop, so they are not on display in store.
