The Duchess of Cambridge wore one of Princess Diana‘s favorite jewelled pieces, the Cambridge Lover’s Knot tiara, last night for the Queen’s winter party at Buckingham Palace. Kate Middleton was seen sporting the sparkly headpiece as she and her husband, Prince William, arrived at the annual diplomatic reception yesterday evening.
Though her full outfit wasn’t photographed, she appears to have worn a beaded white dress, diamond necklace and drop pearl earrings to accompany her late mother-in-law’s precious jewels.
This isn’t the duchess’ first time wearing the famous Lover’s Knot. She recently wore it in July during a state dinner welcoming King Felipe and Queen Letizia of Spain, when she paired it with a lace pink dress.
She also wore the tiara in December 2016, at the same Buckingham Palace event last year, where she donned a bright red lace Jenny Packham gown.
She did the same in December 2015 as well. It looks like the tiara has become Middleton’s wardrobe staple for attending the Queen’s annual winter banquet.
Though the tiara was one of Diana’s favorites, it was actually made for Queen Mary in 1914 by Garrard, jeweler to the British royal family. (It’s also sometimes referred to as Queen Mary’s Lover’s Knot.) The piece is inspired by a tiara owned by the monarch’s grandmother, Princess Augusta of Hesse, who was also the Duchess of Cambridge. After Queen Mary died in 1953, the tiara was passed down to Queen Elizabeth II, then to Princess Diana, and now to the Duchess of Cambridge.
