Selena Gomez’s Marquise Cut Diamond Engagement Ring

When Selena Gomez announced her engagement to Benny Blanco, the ring drew as much attention as the news. She went for a marquise cut diamond, set on a chunky yellow gold band that, as TODAY put it, also sparkles with smaller stones. The couple married in September 2025, and the ring is still the one people bring up when they want something elongated and warm.

The look comes apart into three decisions you can make on your own ring: the shape of the center stone, the color of the metal, and how much diamond runs along the band. Our jewelry consultants can walk you through all three.

The Marquise Cut

A marquise is instantly recognizable: two pointed ends, gently curved sides. It is a modified brilliant cut, so its facets are arranged for both brilliance, the white light a diamond returns, and fire, the flashes of color it breaks light into. GIA notes that because of its shape a marquise looks larger face-up than a round diamond of the same weight, and that many wearers like the way it makes a finger appear longer and more slender.

The shape has been around far longer than any red carpet. GIA dates it to France in the 1740s and records the legend that it was named for the Marquise de Pompadour, a mistress of King Louis XV, because its outline resembled the shape of her mouth. It is also called a navette, Old French for little ship.

Gomez’s choice may not have been arbitrary. TODAY reported that the marquise cut appears in her 2015 collaboration “Good for You,” and that fans read the ring as a deliberate nod to it.

If you want the full picture of the shape, our guide to marquise cut diamond engagement rings and wedding bands covers what to weigh when you choose one and how marquise diamonds work in a wedding band.

Yellow Gold and Diamonds Along the Band

Yellow gold is the warmest of the bridal metals and it flatters a wide range of skin tones. Against an elongated center stone it gives a ring that heirloom quality, which is most of why this combination reads as vintage and current at the same time.

The diamonds set along the band do the rest of the work. Smaller stones running down the shank carry light around the finger and make the center stone read brighter by contrast. Their scale is what separates a delicate band from a bold one, and it is worth trying both before you decide. If the metal is the part you are still weighing, our guide to choosing a yellow gold engagement ring and wedding band compares 14k with 18k and covers pairing a band with your ring.

A celebrity photograph is a starting point, not a specification. We have been helping couples choose engagement rings since 1921, and the useful part of that experience is knowing which details actually change how a ring looks on a hand rather than in a close-up.

Our diamond experts will set marquise stones of different ratios side by side so you can see the difference, show you how each setting protects the points, and compare natural against lab-grown at the same scale. Our master jeweler handles custom work in house. You will find us in showrooms across California, Arizona, Texas, and Washington.

Frequently Asked Questions

What kind of engagement ring does Selena Gomez have?

A marquise cut diamond on a chunky yellow gold band set with smaller stones, according to TODAY’s reporting when the engagement was announced. Published carat and value figures are outside estimates rather than confirmed specifications, so treat them loosely. The shape and the metal are the parts worth borrowing.

What is a marquise cut diamond?

A marquise cut diamond is an elongated stone with two pointed ends and curved sides, cut in the modified brilliant style so it is faceted for plenty of sparkle. Stop by any of our showrooms to see how the shape sits on your hand.

Does a marquise diamond look bigger for its carat weight?

Yes, and that spread is the main reason people choose an elongated shape. When you compare stones, ask for the millimeter dimensions rather than the carat weight alone: two marquise diamonds of identical weight can cover noticeably different amounts of finger depending on how each was cut. Our diamond experts will put a marquise and a round beside each other so you can judge it yourself.

What is the bow-tie effect in a marquise diamond?

It is the faint shadow that falls across the center of an elongated stone, and some of it is expected. The practical test is to view the diamond face-up in ordinary room light and tilt it slowly, because a display spotlight tends to wash the shadow out. Ask us to take a stone out of the case so you can look at it that way.

Are the points on a marquise diamond fragile?

GIA calls the points the most vulnerable part of the stone, though this is a solvable problem rather than a reason to avoid the shape. Some cutters use French tips, a modified facet arrangement at each end that adds durability, and the setting handles the rest. Bring the ring in once a year and we will check that the tips are still secure.

Why choose a yellow gold band?

Yellow gold is warm, classic, and flattering on many skin tones, and it gives a ring a timeless, heirloom feeling. It also sets off the soft glow of a marquise center. We are happy to help you compare metals in person.

Should I choose a natural or lab-grown marquise diamond?

Both are real diamonds with the same sparkle, and the choice comes down to your budget and preferences. A lab-grown stone generally buys you more size for the same spend. We carry marquise diamonds in both and can put them next to each other so you can decide.

Can you create a custom marquise engagement ring?

Yes. Our master jeweler can design a one of a kind ring around the center stone, metal, and band details you choose. Book an appointment and we will guide you through each step.

Do I need an appointment to shop?

Walk-ins are always welcome, but booking ahead means a diamond expert is ready to work with you one on one. You can reserve a time whenever it suits you.
