Queen Elizabeth II has worn the Sapphire Chrysanthemum Brooch in a series of portraits taken with Prince Philip on their honeymoon. The young couple stayed at Broadlands in the UK after their wedding in 1947.
The Queen was given the piece in 1964 when she launched an oil tanker.
She has often worn it for important and for personal events.
The brooch appeared in a portrait with a young Anne, Charles and with Philip, taken in 1950.
It also holds a special meaning relating to the flower it depicts.
It was given to Princess Elizabeth for her 21st birthday and is made of antique Brazillian diamonds.
The Queen’s brooches are often thought to signify her feelings about specific events or to honour people there.
She often chooses her brooches very diplomatically.
One such example is the Queen’s Canadian Maple Leaf brooch depicts the national emblem of Canada. She usually wears the brooch while in Canada or hosting Canadians.
She has also loaned the piece to the Duchess of Cambridge for similar purposes.
