The Hope Diamond
The Hope Diamond, the world's largest deep blue diamond, is more than a billion years old. It formed deep within the Earth and was carried by a volcanic eruption to the surface in what is now India. Since the Hope Diamond was found in the early 1600s, it has crossed oceans and continents and passed from kings to commoners. It has been stolen and recovered, sold and resold, cut and recut. Through it all, the diamond's value increased. In 1958, Harry Winston donated the Hope Diamond to the Museum, and it now belongs to the people of the United States.
