Nobody knows how old this whopping 106 carat diamond actually is, but it is recorded as far back as 1300, in a curse from an old Hindu text. Afterwards the jewel moved around India, Persia and Afghanistan as a spoil of war, before being gifted to Queen Victoria. She wore it in a brooch, and it was then passed down to Queen Mary, Queen Alexandra and Queen Elizabeth (the Queen Mother) to be worn in their Queen Consort crowns. It currently sits in the Queen Mother's crown in the Tower of London.
