In the film, Cartier provides jewelry originally customized for the Duchess of Windsor. Jewelry was also lent to others during the screening. Madonna stepped onto the red carpet to add luster to the retro theme. Madonna wore them to the Venice Film Festival and played the Duchess of Windsor in the film. These jewels include three antique diamond bracelets made by Cartier around 1920, and a replica cross bracelet given to wallis simpson by the Duke of Windsor, which the Duchess of Windsor wears almost every day.
It is reported that Madonna also participated in the discussion of the film content. Finally, everyone agreed that there must be some expensive and exquisite legendary jewels in the love story of the Duke and Duchess of Windsor, and Cartier made faithful copies according to his design documents in London, Paris and new york. In addition to an emerald engagement ring, this key jewel also has an iconic "cross" bracelet-a series of brightly cut diamonds. From 1933 to 1944, the Duchess of Windsor connected nine jewelry crosses, which were given to her by the Duke of Windsor to commemorate the milestone of their common life.
This "cross" bracelet consists of nine white gold crosses set with precisely cut colored gems: aquamarine, emerald, ruby, sapphire, amethyst and rectangular cut diamond. There are dates, love words and "little secrets" on the back of the cross. Cartier's updated record in 1957 is that this bracelet has been remake in the film, and the original has been entrusted to the Paris studio for maintenance.
