How Pearls Form • A piece of sand or grit gets inside the oyster shell. • Natural pearls also have parasites growing on their shells. • The oyster begins to cover the grit with a shell like material, called Nacve. • As more layers are added, the pearl takes shape. • A pearl takes an average of 10 years to become mature. • About 20% of oysters contain a pearl

  3. Pearl Diving • A pearl diver had a dangerous job. • He wore protective clothing and had to deal with weather and water conditions. • The diver would go to the ocean floor and search for oyster fields. • He place them in his basket and return to the boat. Boats had many divers searching for oysters. • Divers can stay underwater for 1-2 minutes. Normally they would find just one or two pearls in 50 or 200 shells!
