The tiara in question? Queen Victoria's "Oriental Circlet," which Gerrard describes as one of "the most important Victorian-era jewels in the Royal Collection." It's also extremely heavy thanks to 2,600 diamonds.

So, how did Kate keep this thing on? As Vanity Fair pointed out, a photo of the Princess of Wales talking to King Charles at the state dinner they were attending shows her trick: the tiara is affixed to Kate's head using strands of her own hair tying it in place.

Genius! Will come in super handy next time I have to wear a tiara and it simply won't stop falling off my head.

Some more tiara lore while we're here? The "Oriental Circlet" was created for Queen Victoria as a gift from her husband Prince Albert in 1853, and was passed to Victoria’s daughter-in-law, Queen Alexandra, who gave it to The Queen Mother, who gave it to the Queen.
