A Rare Encounter: The Hope and Wittelsbach-Graff Diamonds on display at NMNH


For the first time, the world’s two most extraordinary blue diamonds appear together.


On public exhibition for the first time in more than 50 years, the Wittelsbach-Graff Diamond will join the Hope Diamond in the Harry S. Winston Gallery at the National Museum of Natural History from January 29 through September 1, 2010.

“The Wittelsbach-Graff Diamond is an object of intrigue and legend, certainly one of the great gemstones of the world. We are thrilled to present this icon of history—and gemology—to the public for the first time since it was displayed at the Brussels World’s Fair in 1958.”
- Jeffrey Post, curator of the National Gem Collection

A 31.06 carat diamond of flawless clarity, treasured and worn by European royalty, the Wittelsbach-Graff displays the same rare blue color as the Museum’s 45.52 carat Hope Diamond. Both originated in India. Did they come from the same mine centuries ago—perhaps from the same rough stone? Smithsonian scientists and colleagues will analyze the two gems and explore these possibilities while the Wittelsbach-Graff is on loan here this year.

This exhibition was made possible through the generous support of Graff.
