Smithsonian Museum Home to the Largest Diamond Found in Arkansas
The Smithsonian Museum in Washington D.C. is now the home of a rare Arkansas diamond that hasn't been seen since 1974 in the United States.
The "Uncle Sam Diamond" is said to be the largest ever found in the U.S. was at Arkansas' Crater of Diamonds State Park in Murfreesboro. The diamond was discovered in 1924 in the park, according to Glen Worthington, the author of several books on diamonds in Arkansas.
The "Uncle Sam," 40.23-carat diamond has been in custody at the Smithsonian for 3 years under secrecy until now. The rare diamond is a Type II diamond found deep below the ground's surface up to 497 miles. Only one to two diamonds are classified as Type II and they are the most chemically pure diamond having the highest thermal conductivity.
