A well-dressed man entered a famous jewelry shop. He explained that he wished to buy a pearl for his wife’ s birthday. The price didn’t matter, since business had been very good for him that year. After examining a nice black one that costs $5, 000, he paid for the pearl in cash, shook hands with the jeweler, and left.

A few days later the man returned and said that his wife liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality as she wanted a pair of earrings made. "Can you give me any advice on how to get such a pearl?" said the man.
