The Cannes Film Festival 2026 has officially started, with magnificent jewelry hitting the red carpet at the Palais des Festivals et des Congrès. A-listers like Bella Hadid, Demi Moore, and Jane Fonda have arrived for the Opening Ceremony in impressive suites of dazzling natural diamonds.
Since its early days in 1946, the film festival has taken over the resort town’s renowned Croisette. Each spring, a glamorous menagerie of international movie stars and supermodels heads to the south of France to grace the red carpet leading up to the steps of the convention center. The quintessential venue to showcase jaw-dropping diamonds, Cannes’ famously strict formal dress code always calls on couture creations and mega-watt gems and jewels.
Let me set the scene. Against the backdrop of the French Riviera, palm trees sway in the breeze, mobs of cameras flash, and the energy of the red carpet reaches a fever pitch. Diamond chandelier earrings graze the shoulders of cinema’s most elite. Intricate bib-style necklaces drape across countless décolletages in diamonds, and wrists are stacked to the nines in blinged-out bangles and bracelets. Headpieces could double as historic heirlooms borrowed from the royal vaults.
