Queen Elizabeth is giving us a rare peek into her own jewelry box — and it's quite the dazzling display!

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.

"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.

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.

The Flame-Lily Brooch, which represents the national flower of Zimbabwe and Zambia, will be exhibited The brooch is particularly poignant, as it was pinned to the Queen's mourning clothes when she arrived back in Britain from Kenya after the news of her father's death in 1952.

Also in the collection is the Queen's Australian Wattle Brooch, presented to Elizabeth by the government and people of Australia on the monarch's first visit there in 1954. As one of the larger brooches in the Queen's collection, it is often worn for celebratory events, such as the wedding of Prince Charles and Camilla in 2005.
