The largest uncut diamond from North America will go on display Thursday at the Smithsonian National Museum of Natural History, according to the museum.
The Foxfire Diamond will join the museum's Harry Winston Gallery Thursday through Feb. 16.
At more than 187 carats, the Foxfire Diamond is more than four times bigger than the gallery’s famous Hope Diamond.
More than 100 million people have visited the Hope Diamond, a blue stone cut into a 45.52 carat heart-shaped diamond, which Harry Winston donated to the Smithsonian in 1958, the museum says.
The Smithsonian’s time line of the diamond says it was originally 115 carats when purchased by King Louis XIV in 1669.
According to Bloomberg, the Foxfire Diamond was found in the Diavik Mine in Canada.
The diamond has previously been on view for bidders, according to a Bloomberg report, but this is the first time the public will have access.
