India, Dec. 5 -- On Wednesday, the Princess of Wales, Catherine, made yet another regal fashion moment at the state banquet for the German President and his wife at Windsor Castle, UK.

Kate wore Queen Victoria's Oriental Circlet Tiara, a rarely seen historic piece considered one of the most significant Victorian jewels in the royal vaults. Crafted in 1853 for Queen Victoria and set with roughly 2,600 diamonds.Notably, Kate has worn only four other tiaras since joining the royal family in 2011, and this tiara hasn't been publicly worn since 2006, when Queen Elizabeth II last showcased it.
