Diipa Khosla Wears a Custom DiAi Designs Mangalsutra from as she closes her 2026 Cannes Film Festival appearance

A Modern Indian Marriage Symbol just took the global stage, and it happened at Cannes. Global fashion entrepreneur Diipa Khosla closed out the 2026 Cannes Film Festival wearing a custom DiAi Designs Mangalsutra, bringing India’s most enduring symbol of love and commitment to one of the world’s most watched stages. This wasn’t just a jewellery choice. It was a declaration: that Indian culture, Indian tradition, and Indian craftsmanship belong exactly here, at the centre of the world’s most glamorous stage.

The Mangalsutra is not just an ornament. It is one of the oldest and most deeply held symbols in Indian culture, a thread of love, protection, and lifelong commitment that has been worn by Indian women for centuries. It carries the weight of generations. It tells a story before a single word is spoken. And at Cannes 2026, it finally got the global spotlight it has always deserved.

The piece was designed by Disha Shah, Founder of DiAi Designs, a fine lab-grown diamond jewellery brand. Shah took the Mangalsutra, sacred and deeply traditional, and gave it a design language that feels unmistakably modern without losing a single thread of its soul. Two brilliant solitaire lab-grown diamonds sit at its heart, representing the union of two people. The initials “D” and “O” were worked into the design, a detail that made it uniquely their own.  Old meaning, new form. Timeless, but of this moment. Every jewellery piece Diipa wore at Cannes was a DiAi Designs creation. 

And then there’s Oleg. Husband Oleg Buller wore a custom men’s Mangalsutra bracelet by DiAi Designs, his own version of the same statement. He didn’t make it to the South of France, but he didn’t need to. The Mangalsutra has always been hers to wear. A husband choosing to wear one too quietly asks who decided that, and why. Miles apart, they made the same statement together.

“The Mangalsutra is one of the most powerful and recognisable symbols in Indian culture. Our mission has always been to take the Mangalsutra to the world, evolving its design language while preserving its deep emotional soul. Seeing the Mangalsutra at Cannes is a proud moment for Indian craftsmanship, proving our heritage belongs on the global centre stage.”

Diipa taking India to the world with the Mangalsutra is exactly the kind of move that defines her. This is a woman who shows up on her own terms, in the spaces that matter most, and she does it wearing her culture, not concealing it. In a festival full of statements, she saved her most personal one for last.  The Mangalsutra doesn’t get left behind for a global audience. It gets brought to one.

India has given the world yoga, spices, cinema, philosophy, and some of the most breathtaking craftsmanship in human history. The Mangalsutra has always been part of that story, worn quietly, carried deeply. What Cannes 2026 did was give it a stage. What Diipa and DiAi Designs did was make sure it was ready for one.

For DiAi Designs, this is the mission made visible: Indian fine jewellery and the traditions it carries, placed confidently in front of the world. Heritage as identity. Tradition as a statement, not a compromise.

This is what the New-Age Mangalsutra looks like. At Cannes 2026, it made its case to the world.
