Oscars 2025: A dazzling display of jewellery from Cartier, De Beers, Bulgari and more

The Oscars 2025 red carpet wasn’t just about couture gowns and sharp tuxedos—it was a celebration of statement jewellery that ranged from classic to quirky. This year’s theme seemed to scream, “Go Big or Go Home,” and Hollywood’s brightest stars certainly delivered. From archival treasures dripping in diamonds to avant-garde designs that pushed the boundaries of red carpet fashion, the jewellery choices were as much a spectacle as the awards themselves.

Let’s dive into the most unforgettable jewellery moments of the night, featuring both Hollywood icons and Asian stars who brought their A-game to the jewellery scene.

Zoe Saldaña, who won Best Supporting Actress at the Oscars 2025 for her performance in Emilia Pérez, stunned in a crimson Saint Laurent gown, but it was her Cartier Panthères Versatiles necklace that roared the loudest. Featuring a 10.10-carat Zambian emerald at its centre, surrounded by onyx and diamonds, this one-of-a-kind piece looked like it had just leapt out of a Parisian jungle workshop. What’s more, this transformable high jewellery necklace by the maison can also be worn as shoulder jewellery or a bracelet.

Michelle Yeoh in Boucheron

The Everything Everywhere All at Once star turned heads in an electric blue Balenciaga gown, but her Boucheron jewellery and Richard Mille timepiece were the real stars of her look. Among her standout pieces were the Boucheron Plume de Paon asymmetrical earrings, which were paved with natural diamonds and set with rose-cut diamonds. She completed her look with a Plume de Paon large ring, also adorned with diamonds and featuring a rose-cut diamond at its centre.

Scarlett Johansson in De Beers

Scarlett Johansson embraced Old Hollywood glamour in a navy Thierry Mugler velvet gown, but her De Beers “Midnight Aura” diamond necklace stole the spotlight. With over 74 carats of diamonds set in white gold, paired with matching diamond studs, Johansson glittered like a walking constellation.

Isabella Rossellini brought a touch of nostalgia with her Bulgari necklace featuring diamonds and sapphires. Paired with her mother Ingrid Bergman’s vintage diamond-and-pearl earrings, her look was a heartfelt homage to cinematic royalty.

Timothée Chalamet in Cartier

Timothée Chalamet proved (yet again) that men’s jewellery is having its moment by pairing his butter-yellow Givenchy tuxedo with Cartier jewels.

Singer Raye brought drama to the red carpet in a Vivienne Westwood gown paired with Lorraine Schwartz ruby jewellery. Her bold ruby drop necklace added fiery energy to her look, proving that red-on-red can be both daring and dazzling. While this look follows Taylor Swift’s fiery ruby ensemble at the Grammy’s, we wonder if this is a trend that is to stay in the world of red carpet jewellery.

Margaret Qualley in Chanel

Margaret Qualley made an impression in a custom black velvet Chanel gown. However, it was her Chanel High Jewellery reverse necklace that truly stole the show. The piece featured a diamond fringe design that was complemented by matching diamond earrings and an assortment of diamond rings, all from Chanel.
