False gems: 

The classic foreign man must return to his country of origin, but has run out of money and to recover a few dollars is forced to sell off some of its precious stones. Start the deal, the price is really very interesting, but the buyer has any doubts, until at a certain point comes another man who says he is very interested in the goods, because it qualifies as a major jeweler (the 's buyer thinks, "then it is true, the stones are of great value, what a bargain the deal !")... goes on for a little 'and the buyer to check at the end, the stones are his! He went happily in jewelry, but there he discovers that the stones are fake! And he understands all the deception!
