Each platinum cushion cut diamond ring in this collection was designed with that in mind. Our platinum cushion cut engagement rings are crafted with the best of the best: the best lab-grown diamonds hand-selected to ensure they meet industry (and your) standards, the best responsibly sourced platinum metal, and the best designs that’ll make your heart flutter. 

With one of the strongest metals as the foundation, our platinum cushion cut diamond rings are the perfect balance of beauty and durability.
