It’s one of the largest cut-diamonds in the world - but unless you want to meet a violent end, keep a curse-free distance from the Koh-i-Noor Diamond. Now part of London’s Crown Jewels, this Indian gem has a bloody history of colonial conquest. The saying goes that “he who owns this diamond will own the world, but will also know all its misfortunes. Only God or woman can wear it with impunity.”

Over the centuries, many of the diamond’s owners, including rulers or warlords, suffered horrible fates, fueling the curse’s legend. In the mid-19th century, the diamond came into British hands after the annexation of Punjab. Taking the curse into account, the British monarchy made sure it was worn only by female members, setting it into the crows of Queen consorts.
