Selena Gomez wears 8-carat marquise engagement ring in London

Selena Gomez made the marquise ring look less like a bridal whisper than a public declaration. On May 15, 2026, she was photographed leaving dinner at Gymkhana in London in a bronze, beaded midi dress with spaghetti straps and a square neckline, satin pumps, and gold hoop earrings, with the diamond catching the light every time her hand moved.

The ring has become one of the most discussed engagement styles of the past year because it refuses to disappear into the hand. Widely described as an 8-carat marquise-cut diamond on a yellow-gold pavé or eternity band, it reads elongated and crisp, a silhouette that stretches the finger and throws off a bright, knife-edge flash. That same shape can also be unforgiving in daily wear: the pointed ends demand a secure setting, and the stone’s length makes snag risk part of the equation. Gomez wore it with a fitted metallic look, which only sharpened the effect. This is a ring that wants clean lines, confident styling and a hand that is not hidden.

The attention makes sense. Marquise diamonds account for less than 5% of diamonds sold today, so the cut still feels unusual enough to stop the eye. Jewelers have estimated Gomez’s stone anywhere from about 4 to 9 carats, with Ann Grimmett of Jared placing it at about 6 carats and roughly $225,000. Other specialists have said it is likely closer to 8 carats, while broader valuations have ranged from about $100,000 to as much as $1 million. However it is priced, the ring is clearly built to read from across a room.

Its appeal is not only scale but narrative. Gomez revealed the ring on Instagram on Dec. 11, 2024, after Benny Blanco proposed following about a year of dating. Blanco later said the original design included large baguettes at the sides before Gomez asked for something simpler, and those extra stones were repurposed into earrings. The cut also fits Gomez’s own imagery, since she had already likened herself to a marquise diamond in her 2015 song Good for You.

That lineage reaches back to 18th-century France, to Louis XV and the Marquise de Pompadour, which helps explain why the shape still feels aristocratic rather than trendy. On Gomez, the marquise works because it is both polished and slightly theatrical, a diamond that can survive the red carpet and still make sense with a dress, a dinner reservation and a very modern kind of visibility.
