In 1839, a blue diamond weighing over forty-five carats appeared in the collection catalogue of London banker and diamond collector, Henry Phillip Hope.
It would become known as the Hope Diamond, and is famously alleged to have been surrounded by bad luck.
Many owners of the cursed gem met with a grisly death, family tragedy, or a hapless fate.
King Louis XVI and Marie Antoinette who owned the diamond were beheaded.
Other owners and their families experienced suicides, marriage break-ups, bankruptcy, deaths in car crashes, falls off cliffs, mental breakdowns, and deaths through drug overdoses.
Most grisly of all was perhaps the death of the man who discovered—or some say, stole—the diamond in 1642.
Today, spectators gaze in awe at the Hope Diamond through a thick glass in its case at the National Gem Collection of the Smithsonian Institution, Washington D. C.
