TEST 4 – The Pearl 
 
A. 
The pearl has always had a special status in the rich and powerful all through the history. For 
instance, women from ancient Rome went to bed with pearls on them, so that they could remind themselves 
how wealthy they were after waking up. Pearls used to have more commercial value than diamonds until 
jewellers learnt to cut gems. In the eastern countries like Persia, ground pearl powders could be used as a 
medicine to cure anything including heart diseases and epilepsy. 
B. 
Pearls can generally be divided into three categories: natural, cultured and imitation. When an 
irritant (such as a grain of sand) gets. inside a certain type of oyster, mussel, or clam, the mollusc will 
secrete a fluid as a means of defence to coat the irritant. Gradually, layers are accumulated around the 
irritant until a lustrous natural pearl is formed.
