The Hope Diamond is donated to the Smithsonian Institution by New York diamond merchant Harry Winston.

The Hope Diamond is one of the most famous and mysterious gemstones in the world, renowned for its extraordinary deep-blue colour, immense value, and legendary curse. Its history dates back to the 17th century, when French gem merchant Jean-Baptiste Tavernier acquired a large blue diamond, weighing approximately 112 carats, believed to have originated from the Kollur Mine in Golconda, India. Tavernier sold the stone to King Louis XIV of France in 1668, and it became part of the French Crown Jewels. The diamond was subsequently recut into a 67-carat gemstone known as the French Blue and was worn by members of the French royal family. During the French Revolution, the diamond was stolen in September 1792, along with numerous other royal treasures, and disappeared for more than two decades.

In 1812, a remarkable blue diamond weighing approximately 45.5 carats appeared in London, in the possession of diamond merchant Daniel Eliason. Researchers later established that this gemstone had almost certainly been cut from the stolen French Blue. The diamond eventually came into the possession of King George IV of Britain, although the circumstances surrounding its ownership remain uncertain. By 1839, it was recorded in the collection of wealthy London banker Henry Philip Hope, from whom it acquired its famous name. The diamond remained in the Hope family for several generations before being sold in 1901 to settle financial difficulties. Over the following decade, it passed through several dealers and owners, eventually being purchased in 1911 by wealthy American socialite Evalyn Walsh McLean. During this period, stories circulated about a supposed curse associated with the diamond, claiming that its owners suffered misfortune, financial ruin, and premature deaths. Although these tales contributed enormously to the diamond’s reputation, historians generally regard the curse as a mixture of exaggeration, coincidence, and sensational publicity.

Following Evalyn Walsh McLean’s death in 1947, the Hope Diamond was purchased in 1949 by celebrated New York jeweller Harry Winston, who displayed it at exhibitions and charitable events across the United States. In 1958, Winston donated the diamond to the Smithsonian Institution’s National Museum of Natural History in Washington, D.C., famously sending the priceless gemstone through the United States Postal Service in a registered package. Today, the Hope Diamond weighs 45.52 carats and remains one of the Smithsonian’s most popular attractions. Its distinctive blue colour results from trace amounts of boron within its crystal structure, while its unusual ability to glow reddish-orange under ultraviolet light adds to its scientific fascination. Modern research has also helped confirm its connection to the original French Blue diamond. Valued at hundreds of millions of dollars, the Hope Diamond continues to captivate visitors with its remarkable beauty, royal connections, and centuries of intrigue, making it one of the most celebrated jewels in history.
