The Princess of Wales stunned in a sparkling blue dress with a cape, and debuted a tiara she had never worn before. Although Kate Middleton usually favors the Lover’s Knot tiara, Princess Diana’s favorite, this time she chose the Indian Circlet, or Indian Ruby Tiara.

Originally designed for Queen Victoria in the 1850s by Prince Albert, it is a crown relic, meaning Elizabeth technically inherited the right to wear it in 1952 upon becoming queen. However, it was one of the Queen Mother’s favorites, and she kept it until her death fifty years later.
