How would you characterize this pearl dealer in chapter 4?

I assume you are meaning the first pearl dealer. He is out to cheat Kino but even he is in awe of the pearl. He looks down on Kino and Kino's kind. The pearl dealer inspects the pearl and tells him that his pearl is like fool's gold, for it is too large and valuable only as a curiosity. Kino cries out that it is the Pearl of the World, and no one has ever seen such a pearl. The dealer offers a thousand pesos, to which Kino says that it is worth fifty thousand and the dealer wants to cheat him. The pearl dealer offers to asks to fetch other dealers for another opinion. Unfortunately, all the dealers are in collusion together under one man.
