Gemstone File
The Gemstone File is a conspiratorial document attributed to Bruce Porter Roberts. In 1975, "A Skeleton Key to the Gemstone File" appeared and is generally attributed to Stephanie Caruana. The "Key" is purportedly a synopsis of Roberts' documents that presents a chronicle of interlocking conspiracies, including claims that world events since the 1950s were shaped by suppressed information, the names of supposed shooters of President John F. Kennedy, and suggested connections between a number of political assassinations which occurred within a relatively short time frame.

Action items
- Read the article's evidence and "investigation" or "reception" sections, and open its cited sources.
- Before sharing anything on this topic, run it through the fact-checkers above.
- Rely on coroner, court and official investigation records.
- Be wary of 'hidden clue' videos and anniversary-timed rumors.
- Wait for verified reporting from multiple independent outlets.
- Watch for 'crisis actor' claims, which have harmed real victims' families.
- Notice when a claim blames a whole group for a secret plot. That's a classic sign of hate propaganda.
- Check resources from the ADL, SPLC or national equality bodies.
- Report hateful content on the platform where you saw it.
- If someone you know believes it, ask what evidence would change their mind, and share one good source, not ten.
Prevention steps
- StopNotice a strong emotion (anger, fear, 'they don't want you to know') before you share. Pause first.
- Investigate the sourceWho is making the claim, what's their expertise, and what do they gain if you believe it?
- Find better coverageRead laterally: open new tabs and see what independent outlets and fact-checkers say.
- Trace claims to the originFind the original study, video or document. Check dates and whether quotes are cut.
- Ask what would change your mindReal theories can be tested. If every piece of counter-evidence 'proves' the cover-up, it can't be.
- Count the peopleBig secret plots need thousands of people to stay silent for years. That rarely happens.
- Talk, don't mockWith friends or family, ask questions, listen, share your own sources calmly. Shame backfires.
