Yes. It happens when a clam gets 1 grain of sand in its mouth, then the grain of sand turns into a pearl (but I don't know how! Sorry!).

And not all clams have pearls in their mouths.There is also a process called culturing where a small piece of clam shell is placed inside an oyster's shell. To protect itself from the irritation caused the oyster coats it with th stuff pearls are made of and a pearl is made. The longer the pearl stays in, years, the bigger it gets. Most of the pearls around today are cultured.Yes it does but it is not made by sand. It is actually made by a parasite entering the clam and the clam coats it with nacre. Nacre is what a pearl is made of. Not sand.
