The Queen received the Flower Basket Brooch as a gift to mark the birth of her first child, Prince Charles.
It was also the year after Her Majesty’s marriage to Prince Philip, when she was still Princess Elizabeth.
Since then, the Queen has worn her Flower Basket Brooch for different royal engagements over seven decades.
The brooch is colourful and is set with multiple different gemstones, including diamonds, sapphires, rubies, and emeralds.
