Elongated Cushion Knife-Edge SolitairePetal Prong Setting

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.
