Smithsonian's hidden treasures
KidsPost offers a sneak peek at the Smithsonian's secret stash of centuries-old artifacts and scientific finds.
Hope Diamond mail wrapper, postmarked Nov. 8, 1958
The Hope Diamond, a 45-carat blue diamond that is one of the world's most famous gems, is one of the Smithsonian's most popular items. When jeweler Harry Winston donated it, he sent it in this envelope by regular first-class mail.
The original envelope is not on display, but a reproduction can be seen at the Smithsonian's National Postal Museum.
