Elongated Cushion Diamond Engagement Rings
The Elongated Cushion Engagement Ring: Softer Lines, Longer Look
The Elongated Cushion takes everything couples love about a classic cushion, the pillowed corners, the warm, romantic fire, and stretches it north to south. The result is a stone that looks larger on the hand than its carat weight suggests and flatters the length of the finger. At Stienhardt, every Elongated Cushion diamond engagement ring is handcrafted in New York's Diamond District and set with an IGI- or GIA-certified lab-grown diamond.
What makes the Elongated Cushion different
- Length without sharpness: You get the finger-lengthening effect of an oval or radiant, but with rounded corners instead of points, softer to wear and less prone to catching.
- Crushed-ice brilliance: The cushion's facet pattern scatters light in small, glittering flashes rather than broad flashes, a warmer, more romantic sparkle than a round brilliant.
- Looks bigger for the weight: Spreading the same carat weight over a longer outline gives the stone more surface area face-up, so it reads larger than a square cushion of equal size.
Elongated Cushion vs. square cushion
Both are cushions, the difference is proportion. A square cushion sits close to 1.00 to 1.05 length-to-width and reads compact and traditional. An Elongated Cushion runs longer, and that single change makes the ring feel more modern and more elegant on the hand. If you have been torn between a cushion and an oval, this is usually the shape that settles it.
Settings that suit the Elongated Cushion
Most of our settings can be built around an Elongated Cushion center stone. A few that suit it especially well:
- Solitaire: Nothing competes with the outline, the cleanest way to show off the elongation.
- Hidden halo: Pavé tucked beneath the gallery lifts the stone and adds sparkle in profile without crowding the shape.
- Halo: A surrounding row of accents exaggerates the length and adds real presence on the finger.
- Three-stone: Tapered side stones echo the elongation and frame the center beautifully.
- Pavé: A line of small diamonds down the band carries the eye along the length of the stone.
How to choose your Elongated Cushion diamond
Ratio is the decision that matters most. 1.15 to 1.35 length-to-width is the range most couples prefer, visibly longer than a square cushion, without looking stretched. Past 1.40 the stone starts to read more like a radiant or an oval. Because the crushed-ice facet pattern hides inclusions well, you can comfortably shop VS2 and still be eye-clean, which leaves more of the budget for size. Every center stone we set is IGI- or GIA-certified, and our gemologists are happy to compare specific stones with you over chat or in person in NYC, by appointment.

FAQ's
An engagement ring whose center diamond is an elongated cushion: a cushion cut stretched into a longer rectangular outline with the same soft, pillowed corners. It keeps the cushion's romantic glow while covering more of the finger.
Choose any setting on this page, then pair it with the exact certified elongated cushion diamond you want from our loose elongated cushion collection. You pick the specific stone by its grades and certificate, and we hand-set and finish the ring in New York.
Shape ratio. A classic cushion is close to square, around 1.00 to 1.10 length to width, while an elongated cushion runs longer, typically about 1.15 to 1.40. The elongated version reads larger for the same carat weight and lengthens the finger the way an oval does, with softer corners.
Face up it usually reads larger for the same carat weight, because the longer outline covers more of the finger. If maximum presence per carat matters to you, elongated shapes like this one are among the best choices.
Both are beautiful and both appear in our inventory. Crushed ice elongated cushions sparkle like shattered glass with many small flashes, while chunkier step-like faceting gives bolder, larger flashes. The stone's video and images on each listing show exactly which look you are getting before you buy.
Solitaires show off the outline most cleanly, halos add overall size, and hidden halos keep the profile sleek while adding sparkle underneath. Because you are pairing your own stone with the setting, any setting on this page can be made for an elongated cushion.
