10. Messika
Valérie Messika’s eponymous brand has become the go-to for modern, fashion-forward diamonds. Founded in 2005, Messika brings a youthful, edgy energy to the often-traditional world of high jewelry. Its brilliance lies in wearable, stackable pieces that appeal to a new generation of stars. At Cannes, you’ll see Messika not just on one or two A-listers, but on a small army of actors, models, and influencers. Its sheer volume of placements and its ability to capture the zeitgeist of cool-girl glamour earns it a solid spot on the list.
9. Harry Winston
When you hear “King of Diamonds,” you think Harry Winston. This American jeweler has a legacy intertwined with Hollywood’s Golden Age, and that prestige carries over to Cannes. While other brands may chase trends, Harry Winston represents
timeless, heavyweight glamour. The house is known for providing some of the most significant and flawless diamonds to the world’s biggest stars for their most important moments. A Harry Winston appearance at Cannes is a statement of arrival, signifying classic elegance and unparalleled quality.
8. Van Cleef & Arpels
In a world of flash, Van Cleef & Arpels offers poetic elegance. Famous for its iconic Alhambra motif and Mystery Set technique, the Parisian maison brings a touch of fairytale whimsy and storied French craftsmanship to the red carpet. Its pieces are often chosen by stars who favor artistry and heritage over sheer carat size. Seeing a Zip necklace or a delicate Perlée bracelet on the steps of the Palais des Festivals is a nod to a quieter, but no less powerful, form of luxury—a connoisseur’s choice.
7. Boucheron
Boucheron is the choice for stars with an artistic edge. Under the creative direction of Claire Choisne, the brand consistently pushes the boundaries of high jewelry with innovative materials and audacious designs, like the famous Question Mark necklace. Boucheron’s pieces are more like wearable sculptures, appealing to actresses known for their bold and discerning style, such as Eva Longoria and Salma Hayek Pinault (whose husband owns Kering, Boucheron's parent company). It’s the brand that says you’re not just wearing diamonds; you’re wearing art.
6. Tiffany & Co.
With the power of LVMH behind it, Tiffany & Co. has staged a formidable comeback on the global red carpet circuit, and Cannes is a key battleground. Leveraging its impressive roster of global ambassadors like Anya Taylor-Joy and Gal Gadot, the brand masterfully blends its American legacy with cutting-edge design. The annual Blue Book high jewelry collection often makes its grand debut on the Croisette, ensuring a steady stream of breathtaking, one-of-a-kind pieces that dominate social media feeds.
5. De Beers
As the company that arguably invented the modern diamond dream, De Beers brings an unparalleled authority to the red carpet. With the tagline “The Home of Diamonds,” the brand leverages its deep connection to the source to create high jewelry collections of exceptional quality and natural beauty. De Beers’ presence at Cannes feels elemental and definitive. When a star wears De Beers, it's a direct connection to the very essence of diamond glamour, a powerful statement backed by decades of history and expertise.
4. Cartier
Cartier is royalty. For over a century, the French jeweler has been synonymous with timeless elegance and iconic design, from the Panthère to the Love bracelet. Its presence at Cannes is a given, a constant thread of refined luxury woven through the festival’s history. Stars like Elle Fanning and Jake Gyllenhaal, who appreciate heritage and unimpeachable chic, gravitate towards Cartier. The brand doesn’t need to shout; its legacy and the instantly recognizable aesthetic of its pieces speak volumes.
3. Bulgari
Bulgari is the master of the modern blockbuster moment. The Roman jeweler has perfected the art of the Cannes takeover with its megawatt ambassadors like Anne Hathaway, Zendaya, and Priyanka Chopra Jonas. Known for its bold use of colored gemstones alongside spectacular diamonds, Bulgari’s Serpenti necklaces and high jewelry creations are designed for maximum impact. A Bulgari moment at Cannes isn’t just an accessory choice; it’s a full-blown, headline-grabbing fashion event that radiates confidence and joyful opulence.
2. The Contenders
Before we get to number one, an honorable mention is crucial. The world of high jewelry is vast, and brands like Piaget, with its mastery of watches and sunny glamour, and Pomellato, with its Milanese chic, are consistently strong players. Independent designers and houses like Graff, known for handling the world’s most fabulous gems, also make unforgettable appearances. This competitive ecosystem is what keeps the Cannes red carpet so exciting, as every brand vies for its moment in the sun.
1. Chopard
There can be only one king of Cannes, and it is unequivocally Chopard. As the official partner of the festival since 1998, the Swiss jeweler’s influence is absolute. Chopard not only dresses a staggering number of A-list stars in its Red Carpet and Green Carpet collections but also literally creates the festival’s most coveted prize: the Palme d’Or. The brand hosts the most exclusive parties and sponsors the Trophée Chopard, which honors rising talent. At Cannes, Chopard isn't just participating in the glamour; it is the architect of it. Its integration into the very fabric of the festival makes its importance untouchable.
