1 Carat Cushion Cut Blue Diamonds

A natural diamond with these characteristics pairs a rare blue hue formed with trace boron over billions of years with the soft, vintage-inspired cushion silhouette. The larger facets produce broad flashes of blue light. At 1 carat, the blue is clearly visible. The combination of extraordinarily rare natural color with vintage-inspired shape creates a distinctive, elegant engagement ring.

White gold and platinum create a cohesive cool aesthetic. Yellow gold creates warm-cool contrast deepening the blue. The cushion's vintage character pairs well with detailed settings in any metal. Rose gold creates a modern, fashion-forward warm-and-cool combination.

Yes, fully durable with 10.0 Mohs hardness. The boron creating blue has no effect on structural integrity. The cushion's rounded corners resist chipping better than pointed shapes, making it one of the more durable shape choices for everyday engagement ring use.
