The Gemstone File is a 17-page document written by a man named Bruce Roberts, who purportedly was connected to a group of elites who ran the world. It covers the "hidden history" of almost every major event from the 1950s through the 1970s, including the death of JFK, the Howard Hughes disappearance, Watergate, and more.

The Gemstone File first started appearing on college campuses and in underground groups in the 1970s. It spread across the nation from there — it was a pretty well-known document back then — and became an underground sensation for its explosive claims.
