I hope she will select Queen Alexandra's Kokoshnik tiara. The diamonds fit with the situation of just coming out of official mourning and it's a piece that has been worn by several queens so not personal to the late queen.
Were she to opt for the Greville tiara it would be too much of a Duchess of Cornwall role instead of underlining with the jewels her new position as Queen.
Im expecting the new Princess of Wales will opt for the Cambridge lovers' knot tiara.
It will be interesting to see if the Princess Royal and or de Countess of Wessex and Forfar will wear new tiara's.
I wish they would start wearing the Q Adelaide instead of the Mary. I hate how it comes to a rise in the centre, the Adelaide is much prettier. But I agree that they would not want to make a point of having access to the late queens collection, and also with the cost of living crisis here in the UK I very much doubt we shall see big diamonds so the rubies, whilst possibly much more valuable might be a good choice.
