1931 De Beers Shuts down the only US Diamond Mine
Who: De Beers Syndicate, US Justice Department
What: De Beers hires US based attorneys to shut down the only diamond mine located on US soil.
Where: Arkansas, USA
Why: Without a diamond mine, the United States would be forced to use De Beers for all industrial diamonds needed for mass production of war machines. De Beers was able to get the Arkansas land to be declared a state park, thus preventing large scale commercial mining.
