Sharon Stone wears custom Garatti necklace with rare bluish-green diamond

Sharon Stone’s Cannes jewelry was built around one unforgettable stone: a 2.02-carat Fancy Intense Bluish-Green diamond, set into a custom Garatti necklace and framed by 13.18 carats of diamonds. The result was less a supporting accessory than the center of the entire look, a polished example of how high jewelry now uses one rare gem to define a red-carpet image.

Stone wore the suite on May 19, 2026, at the 79th Cannes Film Festival during the screening of Diamond at the Palais des Festivals in Cannes, France. Her outfit was identified as Miss Sohee Spring 2026 Couture, with Paris Libby credited as stylist. The clothes gave the look its line, but the jewelry supplied the voltage: matching Garatti earrings and a ring completed the set, keeping the color story tight and deliberate.

That kind of restraint matters in Cannes, where the 2026 dress code reportedly banned nudity and restricted overly voluminous gowns and long trains. With fabric drama curtailed, the most effective way to stand out was through craftsmanship, scale and a stone with personality. Stone’s necklace did exactly that. The bluish-green diamond brought a rare, almost atmospheric color that sits between sea-glass cool and saturated teal, while the surrounding diamonds acted like a halo, sharpening the center stone instead of competing with it.

Garatti, based in Milan, has positioned itself around rare green diamonds and custom high jewelry, and Stone’s appearance fit neatly into that lane. The house’s specialty is not mass-market sparkle but the kind of commission that begins with a single exceptional gem and then builds an entire visual narrative around it. That approach is increasingly what collectors and celebrity stylists are after: pieces that look unmistakably specific rather than broadly luxurious.

Stone’s return also carried its own Cannes weight. One report described the appearance as her first red-carpet outing there since 2022, a reminder that she remains a fixture in the festival’s style memory. More than a comeback, the look showed how bespoke high jewelry is changing the brief for statement pieces: start with a stone that has character, wrap it in a setting that amplifies its color, and let the rest of the ensemble orbit that one decision.
