The 11 Most Stunning Brooches in the Royal Vaults

The 3,106-carat Cullinan diamond was the biggest ever found, and in 1907 — two years after its discovery — it was gifted to King Edward VII. Having been cut into many pieces, the two largest — Cullinan I and II — now sit at the head of the Sovereign's Sceptre and the band of the Imperial State Crown, respectively. The two second-largest — each still the size of a crab apple — were made into a brooch, which was passed down to the queen in the year of her coronation. She has worn the brooch several times publicly, most notably at the Diamond Jubilee Service of Thanksgiving.
