Queen Mary made a stunning debut in one of Queen Margrethe's favourite tiaras as she attended a gala dinner during her and King Frederik's state visit to Norway on Tuesday evening.
The Danish queen, 52, wore the Pearl Poire tiara, which became synonymous with her mother-in-law, 84, who abdicated in January.
The diamond and pearl headpiece was commissioned as a wedding gift from King Frederich Wilhelm III of Prussia to his daughter, Princess Louise, upon her marriage to Prince Frederick of the Netherlands in 1825.
It has a matching brooch, which Mary also pinned to her beautiful lavender gown, created by her go-to dressmaker, Birgit Hallstein.
According to Billed Bladet, the dress is a reworked number first worn by Mary, then Crown Princess, to Prince Carl Philip of Sweden's wedding to Sofia Hellqvist nine years ago.
The A-line gown appears to have been shortened in length, with added sheer sleeves and a pretty organza overlay.
Mary displayed her royal order – the Grand Cross of St Olav – and in another royal first, she wore the Khedive of Egypt Necklace and its matching earrings.

Frederik succeeded his mother, Queen Margrethe, 84, as monarch in January, following her shock abdication.
