In the book The Pearl, the most overt instance of irony was Kino’s expectations of good fortune after he discovered the pearl. He envisions a better life for his family, treatment and education for his son, a church wedding, as well as a rifle. Other people in the community are also hopeful that Kino’s pearl will change their circumstances. Conversely, ill luck proceeds that include life-threatening attacks on Kino’s family and ended with the fatal shooting of Kino’s only child.
Despite common knowledge that Kino was in possession of a very valuable pearl, the pearl buyers decline to buy it and claim it was worth very little.
It is also ironic that prior to Kino’s discovery of the pearl, the doctor wanted nothing to do with the poor couple. He is certain that they could not afford to pay for his services and thus, declined to give them an audience, humiliating them before the villagers. However, when he learns about Kino’s good fortune, he shamelessly brags that Kino’s baby was his patient.
