Hope Diamond - Janet Annenberg Hooker Hall of Geology, Gems, and Minerals

The Hope Diamond, a 45.52-carat deep-blue diamond with a long documented provenance, is part of the Smithsonian National Museum of Natural History’s gem collection and is exhibited in the Janet Annenberg Hooker Hall of Geology, Gems, and Minerals. The gem is presented in a secure, climate-controlled display as one of the museum’s signature objects; it has been moved occasionally for special exhibitions. The museum documents the Hope Diamond’s gemological characteristics and historical ownership in its exhibit information.
