Seven of the world’s most extraordinary diamonds representing a rainbow of colors—red, orange, yellow, pink, blue, blue-green, and colorless—will be on view this summer in “The Splendor of Diamonds,” an exhibit at the Smithsonian’s National Museum of Natural History, June 27 through Sept. 15.

The exhibit in the museum’s Harry Winston Gallery will include the Steinmetz Pink, a 59.60-ct. diamond, considered by some to be one of the rarest, finest, most precious stones the world has ever seen. It was unveiled in May in Monaco and has never before been on public display. The Winston Gallery is the home of the Hope Diamond and other important stones.

Also on view for the first time in the United States will be the 203-ct. De Beers Millennium Star, one of the largest diamonds in the world. Other rare diamonds included in the exhibition are the Heart of Eternity blue diamond; the Moussaieff Red, the largest known red diamond in the world; the Harry Winston Pumpkin Diamond; the Allnatt, one of the world’s largest yellow diamonds; and Ocean Dream, the world’s largest naturally occurring blue-green diamond.

“The diamonds in this collection represent all the important features that make diamonds special to us—size, color and overall quality,” said Jeffrey Post, curator of the National Gem Collection at the Natural History Museum. “Each of the diamonds is the finest of its kind and together with the museum’s gem collection makes for an exhibit of truly historic proportions.”

The principal sponsor of “The Splendor of Diamonds” exhibition is The Steinmetz Group of Geneva, with additional support from the Gemological Institute of America.

The National Museum of Natural History is located at 10th Street and Constitution Avenue N.W.
