Koh-i-Noor
From Tardis Wiki, the free Doctor Who reference
The Koh-i-Noor was a diamond owned by Queen Victoria, among others. There was a myth that whoever owned the diamond must surely die. In 1879, while on the way to a jeweller to have the stone recut, it was used to kill Haemovariform. (DW: Tooth and Claw)
