The 105-carat jewel is currently housed in the Tower of London, glimmering atop the Queen Mother’s 1937 coronation crown. It’s another gem with a rich history of getting plundered. Owned by a succession of sultans, warlords, and rulers, the rock ended up in the English Crown Jewels collection after the British conquered Punjab. Ever since Queen Victoria laid her hands on this diamond (and had it recut to better please her), only female members of the British royal families have worn it. Supposedly, it brings “great misfortune” to men who wear it.
