Smithsonian diamond show extended

“The Splendor of Diamonds,” a display of seven of the world’s most colorful and unusual gems, has been extended until Sept. 30, the Smithsonian’s National Museum of Natural History said Thursday.

One of the gems, the 203-carat DeBeers Millennium Star, will leave the show on Sept. 2 to be returned to its owners. It will be replaced by a 103-carat clear stone, never before displayed, on loan from the Steinmetz Group, the museum said.

Officials said the display was being held over because of its popularity. It had been scheduled to end Sept. 15.

The diamonds are on display in the museum’s Harry Winston Gallery, adjacent to the famous Hope Diamond.
