An elegantly dressed man entered a famous jewelry shop one day. He explained that he wished to buy a pearl for his wife's birthday. The price didn't matter, since business had been particularly good for him that year. After examining a number of beautiful and expensive pearls, he chose an exquisite black one that cost $5,000. He paid for the gem in cash , shook hands with the jeweler, and left.
A few days later the man returned and said that his wife had 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 possibly give me any advice on how to get hold of such a pearl?" said the man. The jeweler regretfully replied, "I would say it's virtually impossible to find an exact duplicate of that pearl. "
The millionaire insisted that the jeweler advertise in the newspaper, and offered $25,000 for the matching pearl. Many people answered the ad, but nobody had a pearl that was just right. Just when the jeweler had given up hope, a little old lady came into his store. To his amazement，she pulled the perfect pearl from her purse "I don't like to part with，"she said sadly." I inherited from my mother，and my mother inherited it from hers But I really need the money."
The jeweler was quick to pay the old lady before she changed her mind. Then he called the millionaire's house to tell him the good news. The millionaire，however nowhere to be found.
The "millionaire" and the old lady were thieves who worked together. The "duplicate" pearl that she sold, the jeweler was actually the same one the "millionaire had bought.
