The Cannes Film Festival 2025 didn’t just roll out the red carpet but it laid down a runway of pure glam. And while we were all heart-eyes for the couture gowns and celebrity beauty moments, it’s no secret that jewelry did all the heavy lifting this year.
From jaw-dropping diamonds to regal emeralds and nostalgic pearls, the red carpet felt like a love letter to high fashion with a gemstone twist.
Whether you live for fashion inspo or are hunting for your next red carpet–worthy jewel (even if that red carpet is just your BFF’s wedding), here’s the ultimate Cannes 2025 recap of sparkles, sass and style advice included.
1. Rihanna: The Diamond Duchess of Cannes
Rihanna lit up Cannes 2025 with iconic Boucheron sparkle and boss-level gemstone energy.
Rihanna owned the Cannes 2025 red carpet like only she can. Her fashion formula was that delicious mix of edgy elegance and unapologetic glam that we’ve all come to expect.
But this time, the spotlight was undeniably on her jewels. Draped in Boucheron High Jewelry, she gave us a full-on sparkle masterclass.
The diamond pendant and earrings added dramatic shimmer with every move, while the Hopi Le Colibri ring, studded with aquamarines, gave her look an ethereal, ocean-inspired twist.
Her look was a lesson in balancing bold gemstones with sleek silhouettes. Want to channel RiRi’s red carpet moment? Lean into colored gemstones like aquamarine—they’re fresh, fun and add personality to every outfit.
2. Scarlett Johansson: Lavender Queen with Rare Bling
A soft purple moment meets powerful sparkle—Scarlett’s look was all about elegance with a twist of rarity.
Scarlett Johansson floated onto the red carpet like a dream in her strapless lavender Prada gown, effortlessly exuding old-Hollywood charm with a modern twist.
But it was the seriously next-level jewelry she brought to the Cannes film festival 2025. Scarlett’s look glittered with a rumored 13.15-carat diamond drop earrings, catching the light (and our hearts) with every flash of the camera.
Her fancy yellow green 2.15-carat diamond ring added an element of rare luxury to her ensemble.
While three diamond line bracelets elegantly wrapped around her wrist offering just the right amount of sparkle to complement her gown. The whole vibe was chic, confident and quietly powerful.
If you’re into soft hues but still want your jewelry to speak volumes, diamond shades like Scarlett’s yellow-green beauty are your new go-to options.
3. Elsa Hosk: Feathered Fantasy with Classic Ice
Cannes Film Festival 2025 got a dreamy twist with Elsa Hosk’s couture feathers and icy diamonds.
Elsa Hosk served vintage glam with a playful twist in her custom feather-trimmed AZ couture gown.
But don’t get distracted by the dress alone—her diamond necklace and matching jewelry made the whole look glisten like frost under moonlight.
When soft textures like feathers meet sharp, clean-cut diamonds, magic happens. Elsa’s red carpet moment was proof that you can mix whimsy with high-wattage sparkle and still look runway-ready.
4. Dakota Johnson: Fringe, Sparkle & Double Glam
Dakota brought old Hollywood glam and high-shine drama to every appearance.
Leave it to Dakota Johnson to drop not one, but two knockout looks at Cannes 2025. First, she shimmered in a sparkling fringe Gucci gown, dripping in Boucheron diamonds that matched the sparkle of the dress stitch-for-stitch.
Then she pivoted to cool elegance during the “Splitsville” photocall in a sleek black side-slit Gucci dress, again styled with that signature Boucheron sparkle.
Her jewelry didn’t scream for attention but it whispered luxury with every step. Also, when you’re going for high-glam, keep your jewels sleek and sparkly, just like Dakota.
5. Bella Hadid: The Emerald Empress
Bella owned the Cannes 2025 red carpet with bold emeralds and ultra-sculpted Saint Laurent drama.
Bella Hadid might’ve worn black to the screening of “Partir Un Jour”, but her jewelry brought the color—and then some.
Her custom Saint Laurent gown hugged her like a glove, but it was the giant emerald and diamond earring studs that stole the spotlight.
The bold green hue paired with her sleek dress felt modern and majestic, a reminder that emeralds are the power move of the moment.
If you’re dressing minimal, let a bold gemstone earring be your one dramatic detail.
6. Zoey Deutch: Chanel Throwback with Diamonds
Channeling retro vibes with modern sparkle, Zoey’s look was a love letter to vintage beauty.
Channeling 1960s French icon Jean Seberg, Zoey Deutch arrived outside her film “Nouvelle Vague” with a retro bob and a tiered custom silk organza Chanel gown.
Her throwback hairstyle made waves, but her delicate diamond jewelry made the whole look feel modern and graceful. Sometimes, it’s not about excess—it’s about the little sparkles that feel just right.
7. Heidi Klum: Rebel Queen of Floral Couture
Breaking the rules at Cannes Film Festival 2025, Heidi’s florals and Lorraine Schwartz jewels made waves.
Heidi Klum brought the drama (and bent the rules) in a massive floral Elie Saab gown with a show-stopping train—even though trains were technically banned this year.
But you know Heidi—she’s going to do Heidi. She paired the rebellious gown with Lorraine Schwartz jewels that added an edge of shimmer to the floral fantasy.
Rule-breakers, take note: When your dress makes a scene, make sure your jewelry holds its own.
8. Adria Arjona: Pistachio Perfection & Golden Goddess
From soft greens to glowing gold, Adria gave us two unforgettable jewelry moments in one festival.
Adria Arjona delivered not one but two show-stopping looks. Her first? A dreamy satin pistachio-hued Louis Vuitton gown accessorized with a diamond choker necklace and matching earrings that felt like the cherry on top of a couture dessert.
Her second look turned up the goddess energy—an ivory draped gown by Christopher John Rogers styled with bold gold jewelry.
If you love switching styles, follow Adria’s lead and change up your metals to match your fashion mood.
9. Stella Maxwell: Sapphire Beauty
At the red carpet event, Stella turned heads with sleek glam and a sapphire statement that spoke volumes.
Stella Maxwell looked like a modern film noir star in her black halter-neck beaded dress by Sirivannavari.
She took it to the next level with a pearl, diamond and sapphire pendant necklace, effortlessly combining timeless elegance with deep gemstone drama.
The mix of textures and hues gave us major jewelry envy—and a reminder that you don’t have to choose just one stone to make a statement.
10. Rosie Huntington-Whiteley: Sleek, Sculptural & Stunning
Rosie nailed minimalism with maximum impact & her diamond drop earrings said it all.
Rosie Huntington-Whiteley kept it polished and powerful in a black strapless Balenciaga column dress, but the real magic sparkled from her Tiffany & Co. diamond drop necklace and earrings.
This look was the epitome of “less is more” done flawlessly. With clean lines and stunning stones, she proved that understated elegance can still scream luxury.
11. Salma Hayek: Jewel-Toned Goddess
Salma served up deep glam at the Cannes 2025 in sapphires, sequins and serious elegance.
Salma Hayek gave us red carpet royalty in a black sequin feather-trimmed Gucci gown, elevated by a rich emerald and sapphire necklace with a matching ring.
These jewel tones played beautifully against the dark dress, giving her look a lush, regal vibe.
If you’re ever unsure which gems to wear—go for the greens and blues. They flatter everyone and always feel luxe.
12. Halle Berry: Crystal Coolness
Halle shimmered like a crystal dream, pairing silver glam with timeless diamond accents.
Halle Berry brought celestial energy to the carpet in her floor-length silver Gucci gown designed with intricate crystal patterns.
She paired it with a diamond bracelet and ring, letting the sparkle carry through from head to toe. Her red carpet moment was proof that diamonds love a little shimmer to dance with.
13. Julianne Moore: Understated Drama
Julianne’s chic diamond fringe earrings were a quiet luxury moment at Cannes 2025 worth noticing.
Julianne Moore walked the Cannes carpet in a custom one-shoulder Bottega Veneta dress, but it was her diamond drop earrings with fringe detail that added the wow factor.
Subtle yet powerful, her look reminded us that you don’t need to wear it all—just wear it well.
14. Diane Kruger: Lace, Gloves & Double Bling
Diane’s look was peak red carpet poetry with vintage details.
Lace, sheer gloves and a black scarf gave Diane Kruger’s look a touch of gothic romance.
But it was the two diamond bracelets, plus diamond earrings and a shimmering ring, that made it pop. Double the wrist sparkle? Now that’s a trend we can get behind.
15. Alex Consani: Debut With A Drop (Of Emeralds)
Cannes Film Festival 2025 welcomed fresh face Alex with emeralds, vintage vibes and model-off-duty allure.
Making her Cannes debut, model Alex Consani stepped onto the carpet in full Gen Z-meets-glam mode.
With a smoky amber eye created by YSL Beauty’s Sam Visser and a show-stopping pair of pear-cut emerald and diamond drop earrings, Alex was the picture of fresh elegance.
Debut or not, emeralds are always a power move—especially when you want to be remembered.
