Elongated cushion-cut center with marquise side stones on an 18k yellow gold band.

More about this design

Will it suit a smaller hand?

It is well suited to it. An elongated cushion is longer than it is wide, so it stretches the finger the way an oval does while keeping the soft, rounded corners that read as gentle and feminine. The marquise side stones continue that lengthwise line. On a petite hand the design looks generous without spilling over the sides, and the dainty band keeps the overall weight light.

How big does the diamond actually look?

Elongated cushions punch above their weight. The long outline spreads the carat across the finger, so this center looks larger than a square cushion or a round of the same weight, and the marquise accents on each side extend the sparkle line even further. The trade off worth knowing: a cushion holds a little more depth than an oval, so two stones of the same face up size can differ slightly in carat. We pick stones that maximize spread.

Wearing it day to day

All stones here are diamond, a 10 for hardness, so durability is excellent. The cushion's rounded corners are naturally less prone to chipping than sharp pointed shapes, which makes this an easy ring to actually wear rather than save for occasions. The marquise side stones have fine tips, so a yearly prong check keeps them secure. The slim 18k yellow gold band is comfortable for full time wear.

Matching wedding bands

A three stone ring like this pairs cleanly with a thin band that does not compete with the side stones. A fine diamond eternity in 18k yellow gold keeps the dainty feel, and a plain gold band gives a crisp modern contrast. We contour either one so it sits snug against the marquise accents.

Celebrity rings in this style

The cushion cut is one of the most photographed engagement shapes of the last decade. Meghan Markle's three stone ring built around a cushion center is the best known example of exactly this layout, a soft central stone flanked by smaller accents. Our elongated take keeps that romance while making the finger look longer.

Questions buyers ask about this ring

What is the difference between an elongated and a regular cushion?

A regular cushion is close to square. An elongated cushion is cut longer in one direction, giving a rectangular footprint. The elongated version flatters the finger more and tends to look larger for its weight, which is why we chose it here.

Why marquise side stones rather than rounds?

Marquise accents point along the finger, so they reinforce the elongating effect of the center and add a vintage, tapered line. Rounds would look softer but shorter. It is a style choice and we can swap them if you prefer.

Is yellow gold a good setting for a colorless diamond?

It can be. Warm gold can make a near colorless diamond look very slightly warmer, which many people love for a vintage feel. If you want the diamond to read as icy white, we would suggest a white metal basket under the stone, which we can do while keeping the gold band.

Can I have a larger center?

Yes. The ring is made to order, so you set the carat weight and we rescale the side stones and band to match. Lab grown and mined options are both available with GIA certification.

Will the band bend or wear thin?

A dainty band is thinner by design, so over many years of daily wear it can show wear like any fine band. We build it in solid 18k gold and can add a touch more thickness on the underside for durability if you ask.
