Not really. A pearl is a way for the clam to wall away an irritant, such as a grain of sand, that is bothering the clam. If there wasn't any irritant, there wouldn't be any pearl.
You have to go underwater which is left to Aphrodite and you have to find a clam. It opens and closes. Try to get the pearl (which is inside the clam) when the clam is open.

you can find a pearl inside of a clam
you just drag a villager behing the clam and (it has to be a child) and he or she will run to the pearl and the and the ation says (jumping on clam) them the child will pick up the pearl and there you go you got the pearl.
wait untill it closes then run up to it and you have to avoid the clam from closing.
Basically you need a clam, and a piece of sand or shell to irritate it, put it in the clam and wait for (i don't know how long) and when the time is right open up the clam and receive your pearl.
