Technicians check water temperatures and feeding conditions daily at various depths, moving the oysters up or down as appropriate.

Periodically, the oysters are lifted from the sea for cleaning and health treatments. Seaweed, barnacles and other seaborne organisms that might interfere with their feeding are removed from the oysters' shells. The shells are also treated with medicinal compounds to discourage parasites. Over time, after many months of growth and care, the oysters are ready for harvest. Those that have survived the many perils of the sea are brought ashore and opened. And then, when everything has gone well, a beauty is revealed -- the result is a lovely, lustrous and very valuable cultured pearl.

How pearls are processed for market

Saltwater cultured pearls can never be a mass-produced, factory-like product. The whims of unpredictable Mother Nature do not allow it. Millions of oysters are nucleated every year, but only a small proportion live to produce fine-quality cultured pearls. Many oysters don't survive the nucleating process, others are weak and fall prey to disease. Heavy rains may flood the bays with fresh water, reducing their salinity, and killing the oysters. Sometimes, certain species of phytoplankton undergo explosive growth, creating the dreaded "red tide," which exhausts the oxygen in the water, and suffocates the oysters. Then there are typhoons, the attacks of predators and parasites, lack of sufficient nutrients in the water.
