Since pearls are so rare and possess such a high degree of natural beauty, they have been considered to be among the most splendid of gems for many centuries.

The people of India and Persia (Iraq) were among the earliest to collect pearls, because of the rich fisheries of Ceylon and the Persian Gulf, the Indian and Persian princes in the last century, acquired huge collections of pearls that have never been equaled, these collections would be worth hundreds of millions of dollars today.

Pearls A Natural Wonder

Natural or real pearls are made by oysters and other mollusks. Cultured pearls also are grown by mollusks, but with human intervention; that is, an irritant introduced into the shells causes a pearl to grow. Imitation pearls are man-made with glass, plastic, or organic materials.

Because natural pearls are very rare, most pearls used in jewelry are either cultured or imitation pearls. Cultured pearls, because they are made by oysters or mollusks, usually are more expensive than imitation pears. A cultured pearls value is largely based on its size, usually stated in millimeters, and the quality of its nacre coating, which give it luster. Jewelers should tell your if the pearls are cultured or imitation. Some black, bronze, gold, purple, blue and orange pearls, whether natural or cultured, occur that way in nature; some, however, are dyed through various processes. Jewelers should tell you whether the colored pearls are naturally colored, dyed or irradiated.

Clams, oysters, mussels and many other mollusks with limy shells are known to produce pearls. But very few kinds yield gem pearls of jeweler's quality. The pearl is an abnormal growth of mother-of-pearl, or nacre, imbedded in the soft bodies of these shellfish. It is built up, layer upon layer, in the same way as nacre is added to the lining of the growing shell and always has the same color and luster. For example, over the country, hundreds of good-sized pearls are found each year in the oysters we eat. Unfortunately these have no commercial value regardless of whether they have been cooked or not because they are dull opaque white or purple like the shell of the parent oyster. In recent times almost all pearls of gem quality come from the oriental pearl oyster which has a bright shimmering translucent nacre.

A pearl starts growing when some irritating foreign substance such as a sand grain, bit of mud, parasite or other object becomes lodged in the shell-producing gland called the mantle. Pearls formed in the soft flesh where nacre can be added on all sides are most likely to be spherical and the most highly prized. By far the great majority are flattened or variously distorted and have little value. Size, color, luster and freedom from flaws are other essential qualities. Unlike other gems, such as diamonds, pearls have an average life of only about 50 years. In time the small amount of water in a pearl's make-up is lost and its surface cracks. Because they are mostly lime, necklaces which are worn often are injured by the acid secretions of the human skin.

Though, the pearl is not technically a stone at all, its beauty has earned it a place in the Big 5 of precious stones. Jewelry artists have long appreciated the pearl and continue to utilize its charm in their creations
