The romantic vintage.
The cushion cut diamond is a romantic, vintage-inspired shape that has surged back into popularity. With roots tracing back over 200 years to the old mine cut, today's modified cushion brilliant combines classic pillow-shaped softness with modern faceting for exceptional fire and brilliance.
Every cushion cut diamond in our collection is GIA, HRD or IGI certified and individually selected for superior light performance. Its rounded corners and larger facets produce bold, dramatic flashes of colour — creating a warmer, more romantic sparkle than the tighter pattern of a round brillian

What makes it special
Key Characteristics
Why the oval diamond has become one of the fastest-growing choices for engagement rings and fine jewellery.
Exceptional Fire
Larger facets disperse light into bold, rainbow-coloured flashes. The cushion cut produces more fire than almost any other shape — giving it that signature romantic sparkle.
Soft, Rounded Corners
The pillow-shaped outline with gently rounded corners creates a warm, romantic aesthetic while also making the stone less prone to chipping than sharp-cornered shapes.
Vintage Heritage
Descended from the old mine cut of the 1800s, the cushion carries centuries of diamond-cutting heritage — perfect for antique-inspired and halo engagement ring designs.
Enhances Colour
The cushion cut's open facets beautifully showcase colour in fancy coloured diamonds. It's the preferred shape for yellow, pink and champagne diamonds worldwide.

Expert Advice
Why Choose a Cushion Cut?
Unrivalled Fire & Colour Play
The cushion cut's larger, open facets disperse white light into broad, colourful flashes of fire more dramatically than most brilliant cuts. If you love seeing rainbow sparkle rather than white brilliance, the cushion is your shape.
Romantic, Vintage Aesthetic
The soft, pillow-shaped outline evokes the elegance of antique jewellery. Cushion cuts pair beautifully with halo settings, milgrain details and pavé bands — creating a timeless, romantic look that never goes out of style.
Excellent Value Per Carat
Cushion cut diamonds typically cost 25–35% less than a comparable round brilliant. The combination of lower demand and efficient rough utilisation means you can afford a larger, higher-quality stone within the same budget.
Square or Rectangular — Your Choice
Unlike most shapes, the cushion comes in both square (1.00–1.05 ratio) and elongated rectangular (1.10–1.25 ratio) proportions. This gives you creative flexibility to choose the outline that best suits your style and hand shape.
Ideal for Fancy Colours
The cushion cut's facet structure intensifies colour saturation, which is why it's the most popular shape for fancy yellow, pink and champagne diamonds. If colour is your priority, the cushion showcases it beautifully.

Cushion Cut FAQ
Everything you need to know about buying a cushion cut diamond.
About Cushion Cut Diamonds
What is the difference between a cushion brilliant and a cushion modified brilliant?
A cushion brilliant has a facet pattern similar to a round brilliant — producing broad, bold flashes of light. A cushion modified brilliant has an extra row of facets below the girdle, creating a "crushed ice" or "sparkling water" look with smaller, more scattered sparkles. Neither is objectively better — it's a matter of personal taste. We stock both varieties.
What length-to-width ratio should I choose?
For a square cushion, look for a ratio between 1.00 and 1.05. For an elongated rectangular cushion, 1.10 to 1.25 is the most popular range. Both look beautiful — square cushions are classic, while elongated cushions offer a modern twist and can make the finger appear longer.
Does the cushion cut hide colour well?
