The French state visit to Britain<\/a> this week was a veritable cornucopia of glamour. All eyes, naturally, were on the Windsor Castle banquet on Tuesday<\/a>, which saw Kate Middleton<\/strong><\/a>, Princess of Wales, make her dazzling return to white-tie-and-tiara form<\/a>, but might you have missed the second, though no less regal, gala dinner on Wednesday? Fresh from celebrating their wedding anniversary at Windsor, Prince Richard<\/strong>, the Duke of Gloucester, and Birgitte<\/strong>, Duchess of Gloucester, hosted President Emmanuel Macron<\/strong> and his wife, Brigitte Macron<\/strong><\/a>, for an evening at the Guildhall in London.<\/p>\n Joined by the Lord Mayor and Lady Mayoress of London, Alastair King<\/strong> and Florence Walker<\/strong>, the Duchess of Gloucester wore jewels from the vast Gloucester collection, passed down by Princess Alice. One piece, the Gloucester Honeysuckle Tiara, was originally commissioned by Queen Mary after the succession of her husband, King George V, in 1910. The Gloucester Honeysuckle repurposed the diamonds previously used in Queen Mary\u2019s wedding gifts, the Ladies of England Tiara and the Surrey Fringe Tiara. So significant was the tiara that it once bore the Cullinan V diamond, cut from the largest diamond ever found.<\/p>\n![\"Image](\"https:\/\/media.vanityfair.com\/photos\/687135f0fdf3a98a4fb61361\/master\/w_1600%2Cc_limit\/Tiara_100725_GettyImages-2223688670.jpg\")
