Kate's Evening Look: A Resplendent Gold Silk Gown, The Cambridge Lover's Knot Tiara Pays Tribute to Princess Diana!

At a state banquet for President Trump at Windsor Castle, Kate, Princess of Wales, elegantly wearing the renowned The Cambridge Lover's Knot Tiara, instantly stole the show, commanding the room with a calm and composed demeanor.

Kate, 43, and her husband, Prince William, also 43, joined American politician Donald Trump, his wife Melania, and other members of the Trump family at Windsor Palace for the grand event with King Charles, 76, and Queen Camilla, 77.

The Princess of Wales looked exceptionally elegant in a structured silk crepe gown designed by Phillipa Lepley, layered over a hand-embroidered gold Chantilly lace evening gown.

She carried a matching clutch, completing her look. She also accessorized with medals from the late Queen Elizabeth II and the King's Royal Order. A striking blue sash marked her dress, signifying her status as a Lady Grand Cross of the Royal Victorian Order.

Kate Middleton beamed and radiant as she walked with Prince William into historic St. George's Hall in Windsor. The grand event took place at Buckingham Palace, where renovations were underway.

Kate Middleton wore her chocolate brown braids in flowing waves, with Princess Diana's The Cambridge Lover's Knot Tiara resting gently on top, adding a touch of memorabilia to the glamorous occasion.

The late Queen Elizabeth reportedly gifted The Cambridge Lover's Knot Tiara to Princess Diana on their 1981 royal wedding. However, Princess Diana respectfully declined, opting instead to wear her father's Spencer tiara. It turned out that the tiara was too heavy and gave her a headache.

"The fact that it weighed so heavily on Princess Diana is a testament to its preciousness, encrusted with the finest diamonds and pearls."

"While it's difficult to place a price on such a historic and luxurious piece, our experts estimate its value at approximately £1 million."

Although Kate owns four tiaras, the pearl-embroidered Cambridge Lover's Knot Tiara appears to be her favorite. Of the 15 times the Princess of Wales has worn the tiara, she has chosen it 10 times.

Typically, royals rarely wear their tiaras before 5 p.m., as magnificent jeweled tiaras are typically reserved for formal events. This is one reason heirloom tiaras are often revived and frequently photographed at state banquets.

Royal weddings, however, are an exception. Since the ceremony typically takes place at 11 a.m., the ladies of the royal family are usually exempt from this rule and are allowed to wear dazzling tiaras on their special day.

Tiaras are also often loaned to members of the royal family for their lifetime. Kate Middleton currently has four tiaras to choose from: the Pearl Tears, the Lotus Flower, the Strathmore Rose, and the Cartier Halo.

However, while The Cambridge Lover's Knot Tiara is more elaborate than other tiaras in the royal vaults, it has rarely been seen since its debut on the Princess of Wales' wedding day in 2011.

At a state banquet honoring Donald and Melania Trump, Kate Middleton stole the spotlight, standing out among the royal family and high-profile guests.

The mother of three has been described by royal watchers as "breathtaking" and "breathtakingly beautiful."

The President and First Lady are currently on a state visit to the UK, where they attended the stylish event at Windsor Castle with King Charles, Queen Camilla, Prince William, and Kate.

Kate, 43, looked stunning in a Philip Ripley silk crepe gown layered over a hand-embroidered gold Chantilly lace evening gown. She also wore the Royal Order of the late Queen Elizabeth II and the King, along with a blue sash denoting her as a Lady Grand Cross of the Victorian Royal Order.

Notably, she also wore the famous Cambridge Lover's Knot Tiara. This tiara once belonged to Princess Diana and was kept in a Buckingham Palace safe after her death in 1997 before being passed to Kate.

Diana once said the tiara was too heavy and gave her a headache. Designed for Queen Mary in 1914 by the royal jeweler Garrard, it was made from pearls and diamonds already owned by her family.

Kate Middleton wore her hair down over her shoulders, letting it fall in soft waves beneath her crown. She accessorized her look with a pair of drop earrings.

Prince William wore the blue sash and star of the Order of the Garter, along with another star denoting his Knighthood of the Order of the Thistle and a third star denoting his Grand Mastership of the Order of the Bath.

Finally, he wore four medals—one each of the Golden, Diamond, and Platinum Jubilee Medals of the late Queen Elizabeth II, and the King's Coronation Medal.

King Charles and the President of the United States both spoke at the banquet. During the ceremony, Donald Trump also praised William and Kate.
