Uncle Sam (diamond)

It was found in 1924 in Murfreesboro, Arkansas, at the Prairie Creek pipe mine, which later became known as the Crater of Diamonds State Park.

According to some reports, in 1971 it was acquired by a Boston dealer, Sidney de Young, and sold for US$150,000 to an anonymous private collector.

[7] It is displayed alongside the Canary Diamond, an uncut stone found at the Arkansas site in 1917.

[7] The discovery of Uncle Sam arguably rescued the Arkansas Diamond Corporation, which had a debt over $276,470 (equivalent to $4.9 million in 2023) by that time and was going to be shut down in the winter of 1924.

The value of the diamond was not sufficient to cover the debts, but the discovery lifted spirits enough to keep the surface operations going.
