It is most commonly found in three types of mollusks - pearl oysters, freshwater mussels, and abalone. To protect the inside of their shells from parasites and foreign irritants, the mollusk coats it with nacre.  An organic substance that gives mother-of-pearl its iridescent effect and distinct beauty. This multicolored iridescence is caused by the way light reflects on the layers of nacre on the shell.
