This tiara is a small bandeau of diamonds set in daisy shapes and enclosed in circles with a scalloped edge, so we will call it the Diamond Daisy Tiara. It was made in 1910, and was a wedding gift from King Harald and Queen Sonja to Mette-Marit.
Cate Blanchett wore either this same tiara or a copy in the movie An Ideal Husband. That movie came out in 1999, 2 years before the wedding, so it may indeed be the same tiara. Knowing that Garrard's provided jewels to the moviemakers and that the Norwegian royal family have used Garrard's as a jeweler in the past, it's reasonable to guess that the royal family purchased this in Britain sometime before the wedding.
Since then, it has become Mette-Marit's most frequently worn tiara. (Bonus points to those that can spot the double tiara appearance below.)
As we all know, tiara hair can make or break a diadem's appearance, and I find that to be extra true with this gem. On a good hair day, it's light and delicate and a perfect complement to Mette-Marit's minimalist style. On a bad hair day, it's just a froofy headband.
Can we take a moment to praise good tiara hair? Because even though Mette-Marit has her fair share of sad hair appearances (see: the wedding in Monaco, for one), when she gets it right, she really gets it right.
Ah, bliss.
What do you think: perfection, or not enough?
