Elongated Cushion Diamonds
31 certified elongated cushion diamonds available
The elongated cushion stretches the classic pillow outline into a rectangle — pairing a cushion's soft corners and crushed-ice glitter with the finger-lengthening effect of an oval. It has become one of the fastest-growing shapes in engagement rings.
We classify any cushion with a length-to-width ratio of 1.15 or higher as elongated. The stones below all qualify — and every one is independently certified.

What ratio makes a cushion 'elongated'?+
Anything above roughly 1.15 reads as elongated; 1.2–1.35 is the sweet spot where the stretch is obvious but the cushion softness remains.
Do elongated cushions cost more?+
They typically carry a small premium over square cushions because demand is surging, but still price well below rounds and ovals of equal quality.
Do they show a bow-tie like ovals?+
Less than ovals — the crushed-ice faceting scatters light and masks most bow-tie shadow. Video still tells the real story.
