Hope Diamond at the National Museum of Natural History

The Hope Diamond, a 45.52-carat deep-blue diamond with a long documented provenance, is on public display in the Smithsonian National Museum of Natural History and is one of the museum’s most famous single artifacts. Donated to the Smithsonian in 1958 by Harry Winston, it is conserved and exhibited in a dedicated, climate-controlled case in the museum’s gem and mineral collection. The gem’s unique size, color, and documented history make it a singular object in the museum’s holdings.
