These seven diamonds are among the most rare and valuable in the world. They are being displayed together for the first and only time through the collaborative efforts of the Smithsonian Institution, The Steinmetz Group, and the Gemological Institute of America.

The diamonds range from 5.11 to 203.04 carats in weight. All crystallized from carbon atoms deep within the Earth and endured an explosive journey to the Earth’s surface. One—The De Beers Millennium Star—is composed purely of carbon atoms. The others were tinted rare colors as impurities and defects replaced some carbon atoms during growth.
