Every year, Cannes gives us unforgettable moments in cinema and fashion. But beyond the films, the red carpet has become one of the world's biggest showcases for exceptional jewellery. From rare diamonds to one-of-a-kind high jewellery creations, Cannes is where the finest pieces are seen before a global audience.
The 79th Cannes Film Festival, held from May 12 to 23, 2026, was no exception. Against the stunning backdrop of the French Riviera, celebrities stepped onto the red carpet wearing some of the most remarkable diamond jewellery creations of the year. From dramatic bib necklaces and dazzling chandelier earrings to statement rings that stole the spotlight, diamonds played a leading role in many of the festival's most memorable looks.
Here are the diamond jewellery moments from Cannes 2026 that truly stood out.
Demi Moore in Chopard
When it came to jewellery at Cannes 2026, Demi Moore was impossible to ignore. As a member of the festival jury, she attended numerous events throughout the festival and consistently delivered some of the most spectacular jewellery moments on the red carpet.
Her standout appearance came at the Opening Ceremony, where she paired a custom beaded Jacquemus gown with a breathtaking Chopard five-row diamond bib necklace featuring 226.34 carats of marquise-cut natural diamonds set in 18-karat white gold. She completed the look with 22.87-carat diamond cluster earrings and two rings from Chopard's Haute Joaillerie Collection, bringing her total diamond count for the evening to more than 263 carats.
Throughout the festival, Moore continued to showcase Chopard's finest creations, including dramatic chandelier earrings, statement cocktail rings, and an eye-catching choker from the Chopard Red Carpet Collection featuring 87 carats of emeralds and over 40 carats of diamonds. She undoubtedly set the standard for jewellery glamour at Cannes this year.
Bella Hadid in Chopard
Bella Hadid's return to Cannes after several years away was one of the most anticipated appearances of the festival. She arrived in style at the Garance premiere, wearing a custom Prada ensemble paired with exceptional Chopard Haute Joaillerie diamonds.
Her jewellery included 24.12-carat diamond chandelier earrings in 18-karat white gold, a 16.18-carat diamond bracelet, and a stunning 15.01-carat square emerald-cut diamond ring. Later, at the Chopard Miracle Gala Evening, she elevated her look further with a necklace from the 2026 Red Carpet Collection featuring 33.73 carats of natural diamonds.
Alia Bhatt in Amrapali Jewels & Chopard
Alia Bhatt's Cannes 2026 appearance was a proud moment for Indian craftsmanship and jewellery design on the global stage. Wearing a custom peach silk crêpe corseted gown by Tamara Ralph and styled by Rhea Kapoor, she brought together heritage and modern glamour beautifully.
The highlight of her look was a remarkable necklace by Amrapali Jewels featuring 168.27 carats of rare pink coral, centred around a 5.53-carat Golconda Type IIa natural diamond. Considered among the rarest and purest diamonds in the world, Golconda diamonds come from the historic mines that also produced the legendary Koh-i-Noor.
She completed the ensemble with elegant Asscher-cut diamond earrings from Chopard, creating a look that celebrated both Indian heritage and contemporary luxury.
Tara Sutaria in Messika
Tara Sutaria embraced understated luxury with a satin ivory Vivienne Westwood corset gown styled by Tanya Ghavri. Her jewellery selection perfectly complemented the elegance of her outfit.
She wore the Messika Turaco necklace from the Terres d'Instinct High Jewellery collection, featuring 53 carats of diamonds alongside rare green Sannan Skarn stones. Matching diamond and emerald chandelier earrings and a Concorde pear-shaped diamond ring in 18-karat white gold completed the look.
Barbara Palvin
Barbara Palvin delivered one of the festival's most heartwarming fashion moments when she appeared at the Histoires Parallèles premiere alongside her husband, Dylan Sprouse, proudly showcasing her baby bump.
She wore a custom baby blue Miu Miu gown paired with delicate Chopard Haute Joaillerie pieces, including 12.85-carat floral diamond earrings in 18-karat white gold, a butterfly ring crafted with pear-shaped diamonds, and a classic diamond eternity band.
Isabelle Huppert
French cinema icon Isabelle Huppert brought drama and artistry to the red carpet as the Godmother of the Trophée Chopard ceremony.
Wearing a striking custom crimson Gucci gown, she paired her outfit with an extraordinary cuff bracelet from the Chopard 2026 Red Carpet Collection. Crafted in 18-karat white gold, the piece featured a remarkable 50.99-carat Colombian emerald surrounded by 82.45 carats of natural diamonds.
She completed the look with Haute Joaillerie earrings featuring 36.14 carats of diamonds set in platinum and titanium. It was a powerful reminder that jewellery can be every bit as artistic as fashion itself.
Cannes 2026 proved once again that natural diamonds remain at the heart of red-carpet glamour. While the carat counts were certainly impressive, what made these pieces truly memorable was the story behind them. From Demi Moore's spectacular diamond bib necklace to Alia Bhatt's rare Golconda diamond, every creation represented exceptional craftsmanship, heritage, and artistry.
These weren't simply accessories chosen to complete an outfit. They were statement pieces that celebrated design, history, and personal expression.
