The Hall of Geology, Gems and Minerals
The Smithsonian Institution, located in Washington, D.C., is the world’s largest museum and research complex. Inside the Smithsonian’s Museum of Natural History is the Hall of Geology, Gems, and Minerals, which houses one of the world’s largest gem and mineral collections. This permanent collection consists of many rare gems and historical jewels, including two beautiful natural color diamonds which were donated by S. Sydney DeYoung.
In 1962, Sydney DeYoung donated a bright pink pear shape diamond, weighing 2.90 carats, which originated from the Williamson mine in Tanzania. After his death, Sydney bequeathed an extremely rare red-hued diamond weighing 5.03 carats, one of the rarest and largest red diamonds in the world. In addition to these contributions, DeYoung has helped advise the Smithsonian in it’s quest to acquire other special gems.
