The jewel, which the royals call the “Palm Leaf Brooch,” was made by Cartier in 1938. Queen Elizabeth the Queen Mother commissioned the piece herself, supplying the diamonds to be placed in the platinum setting. The jewel is designed to reflect a traditional curved boteh design, which has Persian roots. The pattern was also used extensively in artwork and art objects from India, including the palm-shaped sarpech ornaments worn by Indian princes on their turbans.
And, because the design was later imported to Scotland and popularized by textiles produced in Paisley, the motif also has important resonance for those with Scottish heritage, including the Queen Mother. The combination of national references makes the piece a natural choice for a Commonwealth Day celebration.

The Queen Mother began wearing the brooch shortly before the outbreak of World War II, and it remained a mainstay in her jewelry collection for the next sixty years. One of her most famous appearances in the jewel took place in February 1952, when she wore it during the public mourning for her late husband, King George VI. She wears the brooch in the famous “Three Queens in Mourning” photograph taken of Queen Elizabeth II, Queen Mary, and Queen Elizabeth the Queen Mother outside Westminster Hall in London, where the late King lay in state.

When the Queen Mother died in 2002, her jewelry, including the brooch, was inherited by her daughter, Queen Elizabeth II. While the late Queen set aside many pieces of her mother’s jewelry, offering some of them to other family members (like Camilla and Catherine) as loans, she quickly incorporated the Palm Leaf Brooch into her regular jewelry rotation. Like her mother before her, the Queen wore the brooch for all sorts of occasions. This memorable appearance, from the wedding of Lady Gabriella Windsor in 2019, features the brooch pinned to a vibrant pink coat.
