This is one of several reasons why larger pearls can yield higher values. To protect itself, the mollusk secretes the substances aragonite (a mineral) and conchiolin (a protein), which are the same substances it secretes to form its shell.
Instead, A Pearl Forms When An Irritant Such As A Wayward Food Particle Becomes Trapped In The Mollusk.
