Queen Elizabeth wears favourite chrysanthemum brooch for Commonwealth Day address

In April 1948, the Queen wore the brooch for the unveiling of a statue of Franklin D. Roosevelt in Grosvenor Square, London, and again a few weeks later for a visit to Paris, where she delivered a speech about the dangers of nationalism.

The monarch has worn the sapphire and diamond item for many photographs, including in 1950 for a family portrait with her husband and babies Prince Charles and Princess Anne.

In 1947, the Queen matched the brooch with a patterned dress, wool coat, and pearl earrings for a series of portraits with the Duke of Edinburgh during their honeymoon at the Broadlands estate in Hampshire.

The royal couple re-created these images, again at Broadlands, in 2007 to celebrate their 60th wedding anniversary.
