Pearls grow in pearl-producing mollusks. Natural pearls occur when a mollusk's mantle tissue becomes damaged either by parasitic intrusion or damage to the shell. The mantle contains epithelial cells, which are responsible for the nacre deposition on the inside of the shell. If these cells become dislodged when the mantle is damaged, they may continue to deposit nacre within the body of the mollusk, creating a pearl.
A grain of sand neverproduces a pearl. This is a myth.

The oyster makes a peal when a grain of sand gets trapped in its shell. The sand is covered layer by layer over the time it spends in the oyster until the oyster dies.

What does a natural pearl look like?
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!). Then someone goes clam fishing or finds the clam and opens it up to get the pearl. Not all pearls are white. 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.
