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 something so wondrous emerges from an oyster's way of protecting itself is one of nature's loveliest surprises. For the nacre is not just a soothing substance. It is composed of microscopic crystals of calcium carbonate, aligned perfectly with one another, so that light passing along the axis of one crystal is reflected and refracted by another to produce a rainbow of light and color.

Cultured pearls share the same properties as natural pearls. Oysters form cultured pearls in an almost identical fashion. The only difference is a person carefully implants the irritant in the oyster, rather than leaving it to chance. We then step aside and let nature create its miracle. How pearls are cultivated and harvested Early on, pearl cultivation depended entirely on wild oysters. Later you'll learn that, in some cases, the same applies today. But modern pearl cultivation has become more selective.

A natural pearl begins its life as a foreign object, such as a parasite or piece of shell that accidentally lodges itself in an oyster's soft inner body where it cannot be expelled. To ease this irritant, the oyster's body takes defensive action. The oyster begins to secrete a smooth, hard crystalline substance around the irritant in order to protect itself. This substance is called "nacre." As long as the irritant remains within its body, the oyster will continue to secrete nacre around it, layer upon layer. Over time, the irritant will be completely encased by the silky crystalline coatings. And the result, ultimately, is the lovely and lustrous gem called a pearl.

How pearls Form In Oysters

The birth of a pearl is truly a miraculous event. Unlike gemstones or precious metals that must be mined from the earth, pearls are grown by live oysters far below the surface of the sea. Gemstones must be cut and polished to bring out their beauty. But pearls need no such treatment to reveal their loveliness. They are born from oysters complete -- with a shimmering iridescence, lustre and soft inner glow unlike any other gem on earth.

During the European expansion into the New World, the discovery of pearls in Central American waters added to the wealth of Europe. Unfortunately, greed and lust for the sea-grown gems resulted in the depletion of virtually all the American pearl oyster populations by the 17th century. Until the early 1900's, natural pearls were accessible only to the rich and famous. In 1916, famed French jeweler Jacques Cartier bought his landmark store on New York's famous Fifth Avenue -- by trading two pearl necklaces for the valuable property.

But today, with the advent of pearl cultivation, pearls are available and affordable to all.
