I don’t understand it at all. What are they even made out of?

Imagine clams are like little oysters with a secret superpower. Sometimes, tiny grains of sand or food get inside their shells and bother them, like having a splinter. To protect themselves, the clam makes something special called a pearl.
It’s like when you put a band-aid on a boo-boo. The clam covers the annoying thing with layers and layers of shiny stuff called “nacre.” This nacre makes the pearl, and it’s what makes pearls so pretty and shiny. Nacre is made of a thing called calcium carbonate, it’s also found in the chalk your teacher uses, marble, eggshells, snail shells, etc.
So, clams make pearls to keep themselves safe from the things that bother them, and pearls are made of lots of layers of shiny stuff! 😀
