On display in the Smithsonian Institution’s Hall of Gems – among the rare and historical jewels in its permanent collection – are two beautiful natural color diamonds which were donated by S. Sydney DeYoung (1897 - 1986). The first diamond was donated in 1962: a bright pink pear shape weighing 2.90 carats, which originated from the Williamson mine in Tanzania. The second diamond was left as a bequest when Mr. DeYoung passed away: an extremely rare red-hued diamond weighing 5.03 carats. The DeYoung Family is very proud that these special gems can be enjoyed by millions of visitors to the Smithsonian.
