Biominerals: Pearl, Coral, Odontolite

Shot right inside the Muséum national d'Histoire naturelle, with the eminent Professor François Farges, who opens up drawers to show examples of the museum's treasures, in order to answer the always lively questions about gems of organic origin. What makes these marvels come into existence? How does Mother Nature make it happen? See examples of pearls and other biominerals which used to belong to the French Kings and Queens, and enjoy François and Inezita as they discuss the pieces and enjoy answering the popular questions which students ask about biominerals.
