Pearls are an immune response of bivalves to irritants, disease or other contamination in the shell. There is even a parasitic fish that lives in shells called pearlfish, so named because they're occasionally entombed in pearl (5)

Bivalves make their shell from calcium carbonate. They literally crystallize it from ions in the water around them on a scaffold of protein. (4)
