A new exhibit has been unveiled at the Smithsonian’s National Museum of Natural History. “Great American Diamonds” showcases four of the most important diamonds found in the United States
The collection comes from the only two diamond mines that have been active in the United States: the Arkansas Diamond Crater and the Kelsey Lake Mine in Colorado. Together, these sites have produced tens of thousands of carats of rough diamonds
Uncle Sam Diamond
The Uncle Sam Diamond is a 12.42 carat pinkish-brown emerald cut from the largest rough diamond found in the United States. The original 40.23 carat crystal was discovered at Diamond Crater, Murfreesboro, Arkansas in 1924

Freedom diamond
The Freedom Diamond is a cushion of 16.87 carats. The diamond was cut from a 28.18-carat diamond crystal mined in Kelsey Lake, Colorado, in 1997
Canary diamond
The Canary Diamond is a 17.85 carat yellow gold rough diamond crystal discovered in the Diamond Crater in Murfreesboro, Arkansas. This is another of the largest uncut diamond crystals ever discovered in Arkansas. It was discovered in 1917 and later sold by the Arkansas Diamond Company to Washington Roebling, whose mineral collection was donated to the Smithsonian in 1926.
Colorado Diamond Crystal
The Colorado Diamond Crystal is a 6.45 carat rough diamond crystal recovered from a kimberlite host rock during mining operations in Kelsey Lake, Colorado. The octahedron shape is typical of natural diamond crystals
