Catherine opted for the iconic Wales Lover's Knot Tiara, a timeless piece often worn by her for diplomatic receptions. Completing her ensemble were her favorite diamond and pearl earrings, showcasing her refined taste in jewelry. However, the highlight of the evening was Catherine borrowing the late Queen's Bandeau Necklace—a lavish diamond and ruby piece with a rich history. Originally purchased from jeweler Boucheron, it was a cherished gift from Lady Greville to the Queen Mother and later passed on to Princess Elizabeth as a wedding present.
Featuring intricate diamond flowers and single rubies, the necklace formed a striking V-shape, perfectly complementing her pink Marchesa gown. Catherine's choice of a plunging V-neckline in scalloped lace revealed her daring side, departing from her usual conservative style. Despite commanding attention, she gracefully remained in the background, allowing Queen Letizia to take center stage.
The gown's sheer bell sleeves added drama, contrasting beautifully with its soft color and delicate lace fabric. Tradition dictated that Catherine wear a tiara for the state dinner—the diamond and pearl Wales Lover's Knot tiara, beloved by Diana, Princess of Wales. Her ensemble was completed with cherished diamond and pearl drop earrings, adding a touch of sophistication.
Catherine appeared keen to elevate her style as she stood alongside Queen Letizia, often compared on best-dressed lists. Letizia, known for her bold fashion choices, wore an off-the-shoulder red gown paired with a dazzling tiara inherited from her mother-in-law, Queen Sofia. Queen Camilla also made a striking appearance, showcasing the magnificent Greville tiara loaned from the Queen—a treasured heirloom from her late mother.
Guests at the Spanish state banquet enjoyed a sumptuous menu featuring Scottish beef medallions and truffles in Madeira sauce. The opulent setting of Buckingham Palace's ballroom, accompanied by the melodic strains of the Countess of Wessex's String Orchestra, provided a perfect backdrop for the evening.
This white tie Diplomatic Reception annually marks a social highlight for London's diplomatic community, underscoring the royal family's pivotal role in the UK's international relations. Catherine's appearance was a testament to her impeccable style and grace, honoring both tradition and her unique flair, ensuring the state banquet was an unforgettable evening.
Amidst a collection of heirloom jewelry characterized by an Art Deco aesthetic, one exquisite diamond and ruby necklace stands out. Unlike others, this necklace embodies swirling floral and romantic motifs popular during Maggie Anderson's marriage to Ronnie Greville in 1891. Despite modern transformations to earlier pieces, this necklace retains its distinct V-shaped form and large pendant drop.
Bequeathed to Queen Elizabeth (the Queen Mother) in 1942, a time she favored floral and romantic jewels, the necklace remained unworn, passed to her eldest daughter, Princess Elizabeth. In November 1947, Princess Elizabeth received the necklace as a wedding gift, prominently displayed in newsreel footage showcasing her wedding gifts. Reflecting late '40s and early '50s fashion, the Queen had the necklace shortened to rest closer to her throat, enhancing its elegance.
Princess Elizabeth frequently adorned the necklace during gala functions, including a film premiere in London before her 1951 visit to Canada and the United States. Over seven decades of her reign, the Queen occasionally wore the necklace, notably pairing it with the King George IV Diamond Diadem and Queen Mary's Ruby Cluster Earrings in a formal 1987 portrait.
The diamond and ruby necklace transcends time, leaving a lasting mark on the Queen's regal wardrobe and British monarchy history. Its enduring beauty testifies to the craftsmanship and artistry of its creation era.
