However, Camilla eschewed one major royal tradition on her big day: she didn't wear a tiara. While royal brides traditionally sport a sparkling tiara for their walks down the aisle, Camilla opted to sport a golden feathered headpiece by Philip Treacy. The decision sparked commentary, but there were several reasons for the sartorial choice. For one, the wedding wasn't the first for either member of the couple. Charles had previously been married toPrincess Diana, and Camilla was married to British Army OfficerAndrew Parker Bowlesfrom 1973 to 1995. The occasion also wasn't a traditional royal wedding. The couple tied the knot in a civil ceremony followed by a religious blessing rather than a church ceremony. In addition to the lack of tiara, Camilla opted to go with less traditional bridal looks for her big day. She wore two ensembles, both by British design pair Antonia Robinson and Anna Valentine: first a cream silk chiffon dress with a matching coat and hat for the civil ceremony at the Windsor Guildhall, followed by a pale blue chiffon gown with a floor-length, long-sleeved coat, topped with the feathered headpiece, for the Service of Prayer and Dedication at St. George's Chapel.

The Cubitt-Shand tiara was loaned to Camilla by her grandmother, Sonia Keppel Cubitt, and has become a treasured family heirloom of the queen, perTatler. The tiara, which features a large diamond floral spray in the middle of a diamond floral bandeau, was inherited by Camilla's mother, Rosalind Shand, and when she died in 1994, it passed down to the future queen. Camilla has continued to occasionally wear the Cubitt-Shand in the years since her second wedding, and her daughter, Laura Lopes, wore the tiara for her wedding day to Harry Lopes in 2006.

For a Norwegian state dinner in November 2005, the then-Duchess of Cornwall wore the Delhi Durbar Tiara. According toThe Court Jeweller, the tall, platinum and gold circlet piece was created for Queen Mary in 1911, to be worn at a ceremony celebrating her and King George V's coronation as the new emperor and empress of India. The royal couple traveled to Delhi for the celebration, known as a durbar, and, as the crown jewels are not allowed to leave Great Britain, a new tiara was created for the Queen to wear in India. Queen Elizabeth, the Queen Mother, later wore the tiara on the royal family's tour of South Africa in 1947. However, the state dinner in 2005 marked the one and only time Camilla has worn the Delhi Durber tiara to date. It's possible that controversy surrounding its ties to the British colonization of India — which has affected the public perception of other royal jewels, like the Koh-i-Noor diamond — has dissuaded the royals from sporting the piece.

Since her marriage to King Charles, one of Camilla's most worn headpieces has been the Greville tiara. The impressive signature piece is not officially part of the crown jewels, but it was inherited byQueen Elizabeth, the Queen Mother, to whomDame Margaret Grevillebequeathed her entire jewelry collection in 1942. The Queen Mother was notoriously secretive about the collection, which also reportedly includes a diamond necklace that belonged to Marie Antoinette. AsThe Court Jewellerexplains in their breakdown of the collection, for the sake of propriety, she didn't wear any of the pieces in public until the end of World War II. Even then, she kept many of the impressive pieces to herself until closer to the time of her death in 2002. However, she was very fond of the Greville tiara, and it became her signature piece for the remainder of her life. She even wore the unique, geometric circlet in multiple official royal portraits. Upon her death, the Queen Mother passed her jewelry collection on to her only living daughter,Queen Elizabeth. However, the long-reigning monarch never wore the Greville tiara in public, likely due to its significant connection to her late mother. She did, however,agree to loan it to Camillabeginning in 2006, and the current Queen has made it a signature piece of her own. Queen Camilla has since worn the Greville tiara on at least eight occasions, to state banquets, royal galas and even to the official state opening of Parliament. Eddie Mulholland - WPA Pool/Getty Queen Camilla isn't the only recent royal to form an attachment to a piece from the infamous Greville collection. On her wedding day to Jack Brooksbank in October 2018,Princess Eugeniedecided to forgo a traditional veil in favor of theGreville Emerald Kokoshnik Tiara, commonly referred to as the Boucheron Tiara, lent to her by Queen Elizabeth. The tiara is made of brilliant and rose-cut diamonds pavé set in platinum, with a stunning central oval emerald and six more emeralds on either side.The Court Jewellerexplained that the mere existence of the Boucheron came as a surprise to many, as it had never been worn in public by the Queen Mother or Queen Elizabeth herself.
