#9: Koh-i-Noor Diamond – Various Indian and British rulers (India/United Kingdom)
The Koh-i-Noor, meaning “Mountain of Light” in Persian, is one of the most famous and controversial gems in the world, and it remains on display at the Tower of London. Likely mined in India, it passed through the Mughal Empire, Persia, and Afghanistan before reaching Britain in 1850 after the annexation of Punjab, when it was presented to Queen Victoria. Recut in 1852 to 105.6 carats, it became part of the Crown Jewels. A long-standing legend claims the diamond is cursed, bringing misfortune to any man who wears it, which is why only queens have used it.
