Product Details

Design Intent

This design was created to highlight the softness of an elongated cushion cut while adding structure through a clean knife edge band.

From the top, the silhouette is balanced and elegant. From the side, the petal prongs bring a subtle, sculptural detail that lifts the diamond and allows light to move freely through the stone.

It’s a solitaire — but not a basic one.

Why Diamondboi

For over 20 years, Diamondboi has designed and handcrafted fine jewellery for clients who value quality, integrity, and timeless design.

Every piece is created with intention — balanced proportions, secure settings, and craftsmanship meant to last a lifetime.

Natural diamonds, in 60 seconds

A natural diamond formed in the earth over millions of years, and that origin is where its rarity premium comes from. Every diamondboi natural centre diamond is GIA-certified, E–F colour and VS2 clarity or better, and chosen for cut performance first, because cut is what makes a diamond come alive. The side diamonds on a natural ring are natural too, matched to the centre for colour and clarity.

Natural and lab-grown diamonds share the same optical, chemical and physical properties; the difference is origin. Nobody can tell them apart by eye. The only visible differences are the laser inscription on the girdle and the number on the grading report.

Choose natural if the story of origin matters to you. If you would rather put the budget toward a larger or higher-grade stone, the same design is available with a lab-grown centre in our lab-grown collection. Either way, the ring is made the same way, in the same studio, with the same lifetime guarantee. Read the full guide →
