Also known simply as the Diamond Diadem, this symbolic tiara has become more of a ceremonial piece during her reign.

I love this tiara from Queen Victoria's collection and so did the Queen Mother, but it's been worn just once (so far) since it returned to the Queen in 2002.

Worn, it seems, just once by the Queen, this tiara has now found recognition via a loan to the Countess of Wessex, who has worn it on several occasions.
A dozen tiaras worn from her collection, but is this all of them? Maybe not. Her private collection is larger than we can know, so any retrospective is bound to be a selection only. There are others that she has loaned to family members but is not known to have worn herself, and others she may have worn privately (the Halo Scroll Tiara and the Meander Tiara, for example, were both gifted to the Queen, but she hasn't been pictured in either). Plus, there may be other treasures as yet unknown to us, the tiara-loving public.
But this is plenty to play with, so tell me: Which one is your favorite? Vote in the poll embedded below!
