I think I would say it's off the base in the younger pic.
I like the Girls of GB & Ireland too but I think my favorite tiara from Her Majesty's vaults is the Vladimir. I think it's the circles! I love that it's rounded, and the versatility of pearls or the beautiful Cambridge emeralds ... mmmm.
Just imagine if rubies were able to be suspended in those circles! Or even diamond drops!

Slurp!
