Early pearl
cultivation depended entirely on wild
oysters. Now pearl
cultivation is more
selective. Japanese
scientists isolated strains of oysters
possessing superior pearl bearing
qualities. These selectively bred oysters
produce pearls of exceptional lustre and
color clarity. Highly skilled
technicians open the live pearl oysters
carefully, then surgically implant a small
polished shell bead and piece of mantle
tissue in each. The shell bead serves as
the nucleus around which the oyster
secretes layer after layer of nacre, the
crystalline substance that forms the
pearl. The nucleated
oysters are returned to the sea. There, in
sheltered bays rich in natural nutrients,
the oysters feed and grow, depositing
lustrous layers of nacre around their
nuclei. In winter, the oysters are moved
south to warmer
waters. The nucleated
oysters are suspended from rafts such as
these in order to provide the best growing
conditions. Pearl technicians check water
temperatures and feeding conditions daily
at various water depths and then move the
oysters up or down to take advantage of
the best growing
conditions. Periodically, the
pearl-bearing oysters are lifted from the
sea for cleaning and health treatments.
Seaweed, barnacles and other undersea
growths that might impede feeding are
removed from their shells. Then the shells
are treated with medicinal compounds that
discourage parasites from injuring the
oysters. At last, the
oysters are ready for harvest. Those that
have survived such perils of the sea as
typhoons, suffocating red tides, and
attacks from predators are brought ashore
and opened. If everything has gone well,
the result is a lovely, lustrous and very
valuable pearl.
