Queen Elizabeth is impressively serving as the longest-reigning monarch in England's history, according to Buckingham Palace. With such a long and storied record of service, it's no surprise that she has such a notable collection of jewels and clothes, each with its own historical significance.

Admirers of Her Majesty's collection can visit Buckingham Palace to see the Queen's Diamond Diadem, along with portraits and additional jewels, from July to October (via Royal Collection Trust). Outfits from past jubilees will be on display at the Palace of Holyroodhouse, the trust says, and the queen's coronation dress and several brooches she often wears when visiting Commonwealth countries will be at Windsor Castle. According to People, the brooches — including a maple leaf worn by Queen Elizabeth, Kate Middleton, and other members of the family on visits to Canada — are symbols of the queen's dedication to her work.

"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," exhibit curator Caroline de Guitaut told People.
