The Uncle Sam Diamond
The United States has the world’s only diamond mine open to the public. The Crater of Diamonds State Park in Arkansas is a dig-for-fee operation for tourists and rock hounds. Since 1906, more than 70,000 diamonds have been discovered there, including the Uncle Sam diamond, weighing 40.23 carats. To date the Uncle Sam, discovered in 1924, is the largest diamond ever found in the U.S.

Happy 4th of July America!!!
