‘The Thomas Crown Affair’ Star Adria Arjona Flashes 2 Very Different Moods at Tiffany’s Paris Dinner, and Fans Can’t Pick a Favorite

Some celebrity partnerships with luxury houses feel like a paycheck, but the bond between Adria Arjona and Tiffany keeps looking more personal. The ‘Andor’ and ‘Hit Man’ actress has become one of the jeweler’s most visible ambassadors, and her latest Paris appearance showed why the pairing works so well.

Her ties to the brand have grown all year. In January, Tiffany launched its Valentine’s Day campaign ‘Celebrating Love Stories Since 1837’ with Arjona as the star, a short film built on the house’s long storytelling tradition. It was directed by Emmy-nominated filmmaker Justyna Obasi, and Arjona wore HardWear pieces including a graduated necklace, matching earrings and a bracelet.

That relationship reached a new high this week, when Adria Arjona was photographed at the Tiffany & M.A.D. Dinner in Paris during Fashion Week. She posed in front of a navy backdrop bearing Schlumberger’s signature and handwritten script reading “a pencil.”

For the evening, Arjona wore a sleek black dress with a sweetheart neckline, thin straps, and off-the-shoulder detailing. She finished it with a chunky layered chain necklace and a loose updo with face-framing strands.

What really caught fans’ attention was the contrast between the photos. In one, she breaks into a big laugh while leaning toward the camera, while in the other she offers a more serious pose, glancing over her shoulder.

The dinner was far more than a Fashion Week photo op. On September 28, Tiffany announced a 4-year partnership with the Musée des Arts Décoratifs in Paris to restore and digitize the museum’s Schlumberger archive of 10,000 items, including 5,000 drawings.

To mark the occasion, the brand launched ‘I Am Only a Pencil’, an immersive exhibition created with the Virginia Museum of Fine Arts. It follows the path from a simple pencil sketch to a finished high jewelry piece.

Tiffany’s chief gemologist Victoria Reynolds summed up the appeal, telling WWD it was special to be able to “enter the mind of a genius.” The preservation effort also has real urgency, since tracing sheets in the archive have yellowed and grown brittle over time.

The Schlumberger tribute felt especially fitting for Arjona. At the ‘Splitsville’ premiere in Los Angeles last year, she paired a sculptural Loewe dress with the Jean Schlumberger by Tiffany & Co. Bird on a Rock pendant, earrings and rings.

Tiffany’s current direction makes the connection even stronger. The house’s Blue Book collection, Hidden Garden, reimagined several of Schlumberger’s most iconic designs in new color combinations.

Arjona was surrounded by a stacked guest list. Diane Kruger, Rosie Huntington-Whiteley, Greta Lee, Amanda Seyfried, Anya Taylor-Joy and Cynthia Erivo all joined the celebration. Still, many fans online singled her out. One admirer on X wrote that seeing Arjona at Tiffany in Paris simply made sense, adding that the jewelry felt like an extension of her.

The Paris dinner caps off a stylish few weeks for the star. The ‘Onslaught’ actress recently made waves at Milan Fashion Week, where she turned a Max Mara appearance into her own runway moment.

Taken together, these outings show an actress fully comfortable in the fashion world. Arjona moves easily between playful and polished, and her latest photos capture both sides of that energy.

Paris photos often lean on serious, statuesque poses, but Arjona’s laughing shot stands out because it feels genuine. It adds warmth to a look that could have easily read as cool and untouchable.

Her over-the-shoulder portrait, on the other hand, delivers classic editorial glamour, letting the gold chains and bare shoulders do the talking. Together, the 2 images make a strong case that she is one of the most natural faces Tiffany could have chosen.
