Cushion Cut Diamond Guide
Discover the romantic charm of cushion cut diamonds - a soft, pillow-like shape that combines vintage appeal with brilliant sparkle, perfect for those seeking timeless elegance with a unique twist.
What is a Cushion Cut Diamond?
The cushion cut diamond is a square or rectangular shape with rounded corners, creating a soft, pillow-like appearance. Also known as the "pillow cut," this romantic shape combines the brilliance of a round diamond with the vintage charm of antique cuts.
Featuring brilliant-style faceting with typically 58 facets, cushion cuts offer exceptional fire and sparkle. The rounded corners give the stone a gentle, romantic feel that has made it increasingly popular for engagement rings, especially among those drawn to vintage-inspired designs.
The cushion cut's soft, rounded corners create a romantic, vintage-inspired aesthetic that appeals to those seeking both brilliance and unique character.

The History and Origin of the Cushion Cut
The Old Mine Cut's Legacy
The cushion cut's origins trace back to the "old mine cut" of the early 1700s, which was the most popular diamond shape for nearly 200 years. These antique cushions were cut by hand using candlelight, giving them a distinctive, romantic glow.
Modern cushion cuts emerged in the 20th century, combining the romantic appeal of antique shapes with contemporary brilliant-cut faceting for enhanced sparkle. Today's cushion cuts honor this heritage while offering superior light performance and fire.

Expert Tips & Advice
Brilliant vs Modified Cushion
Understanding the difference between cushion brilliant and cushion modified cuts is essential when choosing your diamond. Cushion brilliant cuts feature a traditional faceting pattern that produces consistent, uniform sparkle very similar to a round brilliant — broad flashes of white light and colourful fire that feel familiar and classic. Cushion modified cuts, on the other hand, have additional facets that break light into smaller, more scattered reflections, creating what's often described as a 'crushed ice' appearance. Neither is objectively better; it comes down to personal preference. If you love bold, defined sparkle, go brilliant. If you prefer a softer, more diffused shimmer, a modified cushion may be your ideal choice.
Shape Preference: Square vs Elongated
Cushion cut diamonds come in a range of proportions, from perfectly square to noticeably rectangular, and the length-to-width ratio you choose will significantly affect the ring's overall look. Square cushions with a ratio of 1.00 to 1.05 offer classic symmetry and a balanced, centred presence on the finger. Elongated cushions with ratios between 1.15 and 1.30 create a more slenderising effect, making the finger appear longer and more elegant. When deciding, consider the wearer's hand shape and the style of setting — elongated cushions pair beautifully with sleek solitaire bands, while square cushions shine in halo and vintage-inspired designs.
Ensure Even Light Distribution
One of the most important things to look for when selecting a cushion cut diamond is how evenly light is distributed across the stone. Some cushion cuts can display dark areas or uneven facet patterns, particularly in the corners or centre, which diminish the diamond's overall brilliance and visual appeal. To avoid this, always prioritise stones with excellent cut quality and strong symmetry grades. Viewing the diamond in person or through high-definition video footage under different lighting conditions is the best way to assess light performance. A well-cut cushion should sparkle consistently from every angle, with no noticeable dark patches interrupting its beauty.
Colour and Clarity Sweet Spot
Cushion cuts are quite forgiving when it comes to clarity — their brilliant-style faceting does an excellent job of masking minor inclusions, meaning VS1 to VS2 clarity grades will typically appear completely eye-clean and offer outstanding value. However, cushion cuts can retain and display body colour more readily than some other shapes, so colour grade deserves careful attention. For white gold or platinum settings, G to H colour grades strike the ideal balance between a bright, near-colourless appearance and cost savings. If you're opting for a yellow or rose gold setting, you can comfortably choose I or even J grades, as the warm metal tone naturally complements any slight warmth in the stone. For larger cushions above 1.5 carats, consider moving up one colour grade, as colour becomes more visible in bigger stones.
