As part of her historic Platinum Jubilee celebrations, the Queen is loaning several pieces of her personal jewelry to the Royal Collection Trust to exhibit at the various royal palaces this summer. An array of brooches, which the Queen often wears as a symbolic nod to her hosts during official Commonwealth tours, will be displayed alongside the Queen's Coronation Dress and Robe of Estate — as well as her famous Diamond Diadem — in the U.K. At Windsor Castle from July 7 to September 26, the Queen's majestic Norman Hartnell-designed Coronation Dress and her purple silk velvet Robe of Estate will be shown alongside five brooches that represent the emblems of the Commonwealth as a nod to the same floral emblems embroidered by hand onto the dress.

Royal Collection Trust "I think it serves to underline the significance of emblematic design and iconography of the coronation dress, but at the same time it's really supporting that message of the Queen as head of the Commonwealth and the fact that she has really devoted so much of her reign to that," Caroline de Guitaut, deputy surveyor of the Queen's works of art and curator of the exhibition, tells PEOPLE. From Barbies to Chocolate — All the Special Products Celebrating Queen Elizabeth's Platinum Jubilee The brooches include the Canadian Maple-Leaf Brooch made by Asprey & Co, which was worn by Princess Elizabeth on her first visit to Canada in 1951. Later loaned to both Camilla, the Duchess of Cornwall and Kate Middleton, the piece is instantly recognizable. Kate Middleton wearing the Maple Leaf brooch in Canada 2011.

And lastly, the vibrant Sri Lanka Brooch set — featuring pink, blue and yellow sapphires, garnets, rubies and aquamarine — which was gifted to the Queen in 1981, will sparkle on exhibit too. Royal Collection Trust At Buckingham Palace, the Queen's famous Diamond Diadem — with 1,333 brilliant-cut diamonds, two rows of pearls and diamonds set in the form of a rose, a thistle and two shamrocks to represent England, Scotland and Ireland — will be on display alongside official portraits of The Queen taken by photographer Dorothy Wilding just weeks after the Accession. Inherited by Queen Victoria in 1821, the Queen regularly wears the impressive crown to the State Opening of Parliament. The Queen in her Diamond Diadem.
