Princess Kate typically wears Queen Mary's Lover's Knot Tiara when it comes to formal occasions, and like Princess Diana before her, the pearl-and-diamond piece has become her signature tiara. On December 3, it was widely assumed she'd go for the Lover's Knot once again at the German state banquet, but instead, the Princess of Wales chose one of Queen Victoria's historic tiaras that hasn't been seen for 20 years.
The princess wore Queen Victoria's Oriental Circlet Tiara, a diamond piece accented with rubies that was designed for the late monarch by her husband, Prince Albert. The tiara was a favorite of the Queen Mother's, but was worn only once by Queen Elizabeth, in 2005—and it hadn't been seen in public again, until now.
