Heritage & Craft

Origin

The cushion cut has its origins in the 19th century, where it was a favourite among antique jewellery makers for its distinctive, soft-edged appearance. Over time, the cut was refined by modern cutting techniques to enhance its sparkle while preserving its original charm. Today, the cushion diamond is celebrated for its ability to evoke a sense of history and romance while fitting seamlessly into contemporary styles, making it a bridge between past and present.

How It's Shaped

The cushion cut is defined by its square or rectangular outline with smoothly rounded corners and a complex faceting pattern that provides a blend of brilliance and subtle shadow play. The gentle curves create an inviting, soft silhouette that is both comforting and elegant. The design strikes a balance between a vintage aesthetic and contemporary clarity, resulting in a diamond that feels both nostalgic and modern. Its graceful form makes it ideal for romantic settings and delicate, timeless jewellery designs.
Why This Cut
Cushion-cut diamonds are known for their delicate balance of brilliance and gentle sparkle. The larger, open facets allow light to diffuse softly throughout the stone, creating a warm and inviting luminescence. Its rounded edges help to soften the overall appearance, reducing the emphasis on sharp angles while enhancing its vintage appeal. This cut is particularly effective in concealing minor imperfections, offering a harmonious blend of beauty and practicality that resonates with both traditional and modern sensibilities.
