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.
