Cushion Cut Diamond Engagement Rings | Hatton Garden, London

Some diamonds feel like they were made for love stories. The cushion cut — with its soft, rounded corners, pillow-like form and larger facets that glow with warmth — has been the romantic’s choice for over two centuries. It carries the charm of a vintage era while delivering the brilliance of a modern cut.

At FineDiam, every cushion cut diamond engagement ring is curated in Hatton Garden, London — UK hallmarked and delivered in a luxury gift box. Both lab grown and natural diamond options are available across the collection.

Why Choose a Cushion Cut Diamond?

• Soft, romantic silhouette — rounded corners and a pillow-like shape give the cushion cut a warmth and femininity that no other diamond shape quite matches
• Exceptional fire — larger facets disperse light into vivid flashes of colour; the cushion cut is renowned for its fire and warmth rather than pure white brilliance
• Vintage appeal — favoured throughout the Victorian and Edwardian eras, the cushion cut carries a sense of history and romance that feels genuinely timeless
• Versatile shape — available in square and elongated proportions to suit every hand shape and personal style
• Setting versatility — works beautifully with solitaire, halo, pavé and three-stone settings

Our Cushion Cut Diamond Engagement Ring Styles

Classic Cushion Solitaire
One cushion cut diamond. Pure, romantic elegance. The solitaire lets the stone’s soft geometry and warm fire speak entirely for itself. Available in platinum, white gold, yellow gold and rose gold.

Cushion Halo Rings
A halo of pavé diamonds surrounds the cushion centre stone, amplifying its size and brilliance. The contrast between the soft cushion shape and the sparkling halo creates a truly show-stopping effect.

Elongated Cushion Cut Rings
A rectangular cushion proportion that creates a finger-elongating effect — combining the warmth of the cushion cut with the flattering silhouette of an oval.

Three-Stone Cushion Rings
A cushion cut centre flanked by two side stones — representing your past, present and future. Deeply meaningful and beautifully balanced.

Vintage-Inspired Cushion Rings
Milgrain edging, filigree detailing and floral motifs that honour the cushion cut’s Victorian heritage — crafted with modern Hatton Garden precision.

Lab Grown vs Natural Cushion Cut Diamonds

Both lab grown and natural cushion cut diamonds are real diamonds — chemically identical, equally brilliant, and set in the same precious metals. Lab grown diamonds allow you to choose a larger stone or higher quality grade for your budget. Natural diamonds carry traditional rarity and heritage value. Diamond details and any grading reports are listed on each individual product page.
