Koh-i-Noor

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. Albert, the Queen's husband, constantly had it cut down for it to meet the exact specifications he needed for the light chamber.

In 1879, while being taken to a jeweller to have the stone recut, it was used in combination with the light chamber to kill a Lupine Wavelength Haemovariform. (TV: Tooth and Claw)
