Whether it is for lavish formal events or casual occasions, Crown Princess Mette-Marit of Norway always goes for understated elegance, preferring monochromatic outfits with an emphasis on simplicity. To create a sophisticated look with a touch of restrained sparkle, she has quite a number of royal heirloom jewellery pieces to choose from, too. The Diamond Daisy Tiara A fairy-tale-like tiara is a must for a princess’ wedding . For her nuptials to Crown Prince Haakon in 2001, Princess Mette-Marit donned the Diamond Daisy Tiara, a wedding gift from the King and Queen of Norway. Crafted in 1910, this rather dreamy jewel is a delicate bandeau of white diamonds set in daisy motifs and enclosed in circles with a scalloped edge. The tiara’s simple design complemented the princess’ minimalist style perfectly. Since the princess first wore the tiara on her wedding, it has become her favourite piece of royal jewellery and she can be seen wearing it for formal occasions often.

It has never been recovered. The current tiara is a replica made by Garrard.
