Cushion Solitaire Engagement Rings
A cushion cut is a soft, rounded square with an antique pedigree, and on a solitaire its pillowy shape and warm, chunky sparkle carry a ring on their own. This collection also includes the elongated cushion — a slightly stretched version that lengthens the finger like an oval while keeping the cushion's soft corners. It holds 33 cushion cut solitaire lab-grown diamond engagement rings, from $945, each IGI-certified and made to order in solid 10K, 14K or 18K gold.
Why choose a cushion solitaire
The cushion's larger facets throw broad, warm flashes of light rather than the sharp scintillation of a round, giving it a softer, more romantic, vintage character. A solitaire setting shows that pillow shape off cleanly. The elongated cushion is worth knowing about too: it reads longer and larger on the finger, so if you want a cushion with an oval-like stretch, look for it here.
Styles in this collection
The collection covers classic cushion solitaires and elongated cushions, on four-prong, cathedral and slim knife-edge bands. Metal options span white, yellow and rose gold — yellow especially suits the cushion's antique feel — with centre sizes from about one to three carats.
Lab-grown, IGI-certified
Every cushion here is lab-grown and IGI-certified — the same carbon, hardness and fire as a mined diamond, at a fraction of the price, so a larger centre stays within reach.
Shop with confidence
Each ring is made to order in about two weeks, ships free by express courier in 5–7 days, and is covered by a 30-day return policy, with the IGI certificate included.

How to choose a cushion cut solitaire
Cushions retain body colour more than most shapes because of their large facets, so on a solitaire — where the stone stands alone — colour grade earns extra attention. H or better keeps a cushion cut diamond solitaire ring looking white, especially in white gold; in yellow gold you can drop a grade and save. As a brilliant-style cut it hides inclusions well, so SI1 usually faces up clean, letting you spend on colour and cut instead.
Decide between classic and elongated first: a standard cushion reads soft and squarish (ratio near 1.00–1.10), while a solitaire elongated cushion cut engagement ring stretches to about 1.20–1.30 and wears like an oval with cushion character. On a solitaire the whole outline shows, so check the shape is even and the corners uniformly rounded. Four-prong and cathedral mounts both suit the pillowy shape.
Cushion cut solitaire engagement ring FAQs
What is an elongated cushion cut solitaire?
A solitaire elongated cushion cut engagement ring uses a cushion that's slightly stretched in one direction, so it lengthens the finger like an oval while keeping the cushion's soft, rounded corners. It's a popular alternative to the classic squarer cushion.
Why does a cushion cut look soft and warm?
A cushion's larger facets throw broad flashes of light rather than the fine sparkle of a round, giving a cushion cut diamond solitaire ring its signature warm, romantic, vintage character.
What carat size works for a cushion solitaire?
Cushion solitaires are popular from 1 to 3 carats. A larger stone, like a 3 carat cushion cut solitaire diamond ring, shows off the shape's generous, pillowy spread beautifully.
What metal suits a cushion solitaire?
All three golds work, though yellow gold especially complements the cushion's antique feel. Each ring here is made to order in solid 10K, 14K or 18K gold.
Is a solitaire the best setting for a cushion?
A solitaire shows the cushion's soft square shape and warm sparkle with nothing beside it, and pairs cleanly with any wedding band. It's the purest way to display the cut.
Are cushion cut lab grown diamonds real?
Yes. A cushion cut diamond solitaire made with a lab-grown stone is chemically and optically identical to a mined diamond, IGI-certified to the same standards, and classed by the FTC as a real diamond.
