Cannes Film Festival 2026 Best Jewellery Looks
The Cannes Film Festival 2026 once again transformed the French Riviera into the centre of the fashion and jewellery world, with celebrities arriving in extraordinary couture gowns and breathtaking high jewellery creations.
Known for its timeless glamour and cinematic elegance, Cannes always delivers some of the most sophisticated jewellery moments of the year. Below, we round up the standout jewellery looks from Cannes 2026 and the styles set to inspire the world of luxury jewellery next...
Simone Ashley
The Look:
Simone Ashley embraced effortless Cannes glamour with a sleek, elegant silhouette that felt both modern and timeless. Her styling was refined and understated, allowing her jewellery to take centre stage beautifully.
The Jewellery:
The standout piece was an extraordinary diamond necklace featuring a series of graduating pear shaped diamonds pendants in a flawless 18k white gold setting. The elongated silhouette of the stones created incredible movement and light across the neckline, giving the look a soft, feminine elegance while still feeling red carpet worthy.
Why It Stood Out:
Pear cut diamonds continue to dominate both fine jewellery and engagement ring trends thanks to their romantic shape and flattering elongation. Simone’s necklace perfectly captured the balance between classic sophistication and contemporary luxury that Cannes does so well.

Ruth Negga
The Look:
Ruth Negga delivered one of the evening’s most striking fashion moments with a sculptural, fashion-forward ensemble that paired beautifully with bold gemstone jewellery.
The Jewellery:
Her statement green emerald earrings were impossible to ignore. Featuring classic emerald cut stones, the earrings celebrated the clean lines and rich depth of colour that make emeralds so timelessly luxurious.
Why It Stood Out:
Emerald jewellery continues to rise in popularity as clients look beyond traditional diamonds and embrace vibrant colour. Ruth’s choice felt sophisticated, artistic, and beautifully timeless while also tapping into the growing demand for gemstone-led fine jewellery.

Demi Moore
The Look:
Demi Moore once again embraced classic Hollywood glamour, pairing an elegant gown with jewellery that felt dramatic yet incredibly refined.
The Jewellery:
Her marquise cut diamond necklace was one of the standout jewellery moments of the festival. The elongated marquise diamonds created beautiful fluidity and sparkle around the neckline, while a simple polished 18k yellow gold band added a modern, understated finishing touch.
Why It Stood Out:
Marquise cut diamonds are enjoying a huge resurgence right now and marquise cut engagement rings are everywhere. Demi’s jewellery styling proved exactly why. The combination of bold diamond shapes with minimal polished gold created a look that felt both timeless and very current.

Kiko Mizuhara
The Look:
Kiko Mizuhara leaned into sleek modern elegance with a minimalist look that allowed her jewellery to become the focal point of the entire ensemble.
The Jewellery:
Her platinum necklace featured a striking emerald cut blue sapphire pendant with extraordinary depth of colour and clarity. The cool platinum setting enhanced the vivid blue tone beautifully, creating a clean and contemporary finish.
Why It Stood Out:
Blue sapphires continue to influence both high jewellery and engagement ring design, particularly among those looking for a more individual alternative to traditional diamonds. Kiko’s necklace felt elegant, artistic, and quietly powerful.

Bella Hadid
The Look:
Bella Hadid delivered full Cannes glamour with a dazzling diamond-heavy look that balanced modern sensuality with timeless elegance.
The Jewellery:
While her entire jewellery styling sparkled from every angle, our eyes were immediately drawn to two incredible rings. The first was a platinum Asscher cut diamond ring with a delicate pavé band, while the second featured a pear cut toi et moi style design, also set on a diamond pavé band. Together, the stacked effect felt luxurious, contemporary, and incredibly fashion-forward.
Why It Stood Out:
Asscher cut diamonds are becoming increasingly popular thanks to their vintage-inspired symmetry and Art Deco feel, while toi et moi rings remain one of the biggest engagement ring trends in the world right now. Bella’s styling captured both trends perfectly, proving that statement ring stacks are here to stay.
