A cushion cut engagement ring uses a pillow-like shaped diamond at the centre. The shape of a cushion cut is a little like a square with rounded corners. Some cushion cut diamonds are far more rounded than others, and some are more square. Some are even elongated, similar in shape to a radiant cut diamond.

Similar in shape to Old Mine cut and Old European diamonds, a cushion engagement ring has a beautiful vintage flair.

Cushion cut diamonds appear similar in size to round and princess cut diamonds and aren’t among the largest-looking diamond shapes. Cushion diamond rings don’t typically feature a large spread, meaning much of the carat weight is directly under the crown of the diamond. Unlike this, shapes like pear, marquise and oval diamond engagement rings feature a large spread and therefore appear bigger.

A cushion cut ring says you're romantic and appreciate traditional, timeless style. The cushion cut diamond is rounded, soft, elegant, yet striking and strong, and has a certain feminine charm.

In recent years, several celebrities have been seen showcasing the timeless charm of cushion cut diamond engagement rings, including:

• Meghan Markle – Prince Harry proposed with a trilogy-style ring featuring a 3–4ct elongated cushion cut diamond flanked by two round diamonds. Set in yellow gold and estimated at £200,000–£270,000, it’s a regal and sentimental design.
  

• Louise Thompson – When Ryan Libbey proposed, he chose a cushion cut engagement ring with a diamond halo and pavé diamond shoulders. Glamorous and timeless, it’s a favourite among modern brides. You can get the look with the Cushion Cut Classic Oberon.
  

• Priyanka Chopra – Nick Jonas proposed with a 5ct cushion cut diamond ring, reportedly worth $2,000,000. With top-tier colour and clarity, it’s a bold, luxurious statement.

• Zendaya – Zendaya’s engagement ring is a 5 carat cushion cut diamond set in an east-west orientation, given to her by Tom Holland in 2025.
