Mission: Impossible - Season 1 - Eps 19: The Diamond
Henrik Durvard has taken over the country of Lombounda by military coup, and holds the natives in terror. He has obtained a diamond from the native miners, and the IMF are assigned to take it away from him. In London to auction the diamond, Durvard is approached by the team who offer to top all bids if they get exclusive rights to diamond production in Lombounda. Since Lombounda is not known for its diamond production, Durvard is suspicious. Eventually the team lets him figure out that they have a plan to use his country as a blind to distribute artificial diamonds that they claim they can manufacture. Durvard insists on being part of the scam, and forces the team to ""make"" a diamond from him using a piece off of the original stone. They do so, but when it comes time to fake the real diamond, the machine apparently overloads from the strain. The team slips the diamond out of the machine and leaves, as Durvard and the machine blow up.

Synopsis
Mission: Impossible is an American television series that was created and initially produced by Bruce Geller. It chronicles the missions of a team of secret government agents known as the Impossible Missions Force. In the first season, the team is led by Dan Briggs, played by Steven Hill; Jim Phelps, played by Peter Graves, takes charge for the remaining seasons. A hallmark of the series shows Briggs or Phelps receiving his instructions on a recording that then self-destructs, followed by the theme music composed by Lalo Schifrin. The series aired on the CBS network from September 1966 to March 1973, then returned to television for two seasons on ABC, from 1988 to 1990, retaining only Graves in the cast. It later inspired a popular series of theatrical motion pictures starring Tom Cruise, beginning in 1996.
