Kate Middleton Has Her Pick of All These Royal Tiaras

Possibly the queen's favorite tiara, it's certainly the one she wears the most, including on some Commonwealth coins and banknotes and on her historic first visit to Ireland in 2011. The piece was a wedding present to Queen Mary, purchased from Garrard with funds raised by a committee and then passed down to the queen mother and then the queen. It used to feature pearl spikes on top, but they were later replaced with diamonds.
