The Ambani family’s approach to jewellery has always been bigger is better. Remember the cascade of walnut-sized emeralds and diamonds that were on display during the wedding celebrations of Anant Ambani and Radhika Merchant Ambani last year? So, it’s no surprise that Isha Ambani’s jewellery choice for the Met Gala 2025 perfectly embodied this more-is-more approach.
Arriving on the red carpet, she swept up the stairs in a dramatic Anamika Khanna three-piece set of corset, tailored coat with train, and trousers. The look was styled with a cane, fedora, and, most significantly, a solitaire necklace from her mother’s personal collection that featured two rows of large clear, white diamonds, linked by three more diamonds and finished with a central pendant.
The neckpiece is an homage to the Toussaint necklace, named after Jeanne Toussaint, the director of fine jewellery house Cartier, who was commissioned to design it in 1931 by the former Maharaja of Nawanagar, Ranjitsinhji Jadeja. It was created to house the weighty Queen of Holland diamond, which then weighed 136.25 carats and was considered one of the largest diamonds in the world.
The original piece no longer exists—it was dismantled in 1960 when Cartier bought the Queen of Holland as a standalone stone—but the brand has drawings and photographs of the work in their archives. These were used to recreate it once before—for a pivotal role in the 2018 film Ocean’s 8, where it was draped on the neck of Anne Hathaway—but using zirconium oxide instead of diamonds.
The necklace’s story endures as it enters the culture yet again with Ambani wearing her own version for the Met Gala 2025 today.
