Often referred to as a gift from the sea, pearl’s origin has been an object of folklore throughout history. Early Chinese myths told of pearls falling from the sky when dragons fought. Ancient Persian legend said that pearls were tears of the gods. In classical times, it was believed that pearls were formed when moonbeams lit upon shellfish, while Indian mythology suggested pearls were formed when dewdrops fell from the heavens into the sea.

In truth, pearls are lustrous gems with an organic origin. They are formed inside mollusks such as oysters, clams and mussels when an irritant such as a tiny stone, grain of sand or small parasite enters the mollusk's shell. To protect its soft inner body, the mollusk secretes a smooth, lustrous substance called nacre around the foreign object. Layer upon layer of nacre coats the irritant and hardens, ultimately forming a pearl.

This process of building a solid pearl can take up to seven or eight years. Generally, the thicker the nacre becomes, the richer the “glow” of the pearl and greater its value. While pearls that have formed on the inside of the shell (called blister pearls) are usually irregular in shape and have little commercial value, those that are formed within the tissue of the mollusk are either spherical or pear-shaped and are highly sought-after for jewelry. Most pearls on the market measure 7.0-7.5mm in diameter, but can be found as small as 1mm or as large as 20mm.

Although some pearls are found naturally in mollusks (considered the most valuable), the vast majority of pearls are grown, or cultured, on pearl farms. To instigate this culturing process, a small shell bead, or nucleus, is surgically inserted into the mantle of an oyster. Despite the fact that pearls are harvested in great quantities on pearl farms, producing a quality pearl is an extremely rare event. It is estimated that half of all nucleated oysters do not survive and, from those that do, only 20 percent create marketable pearls.

Cultured and natural pearls can be distinguished from imitation pearls by rubbing them gently against the edge of a tooth. Cultured and natural pearls will feel slightly rough, like fine sandpaper, because of the texture of natural nacre. Imitations will feel quite smooth because their surfaces are merely molded or painted on smooth beads. Since nacre is organic, pearls are quite “soft” and rank only a 2.5-4.5 on the Mohs Scale . The gems are very sensitive and special care should be taken when wearing and storing them.

The value of a pearl is judged by several factors, and high-quality pearl strands should feature pearls well-matched in these factors: “orient,” the lustrous iridescence that’s produced when light is reflected from the nacre, should glow with a soft brilliance; the nacre’s texture should be clean and smooth, absent of spots, bumps or cracks; the shape of a pearl should be symmetrical and generally the rounder a pearl is, the higher its value; and although pearls come in many different colors (depending on the environment and species of mollusk), the most favored are those that have a rose-tinted hue.

Pearls are cultured in a variety of sizes, shapes and colors. Akoya pearls are the classic round pearls found in most pearl jewelry. They are mainly grown in the waters off Japan and are found in a range of hues, including white, cream, pink and peach. Mabe pearls are grown in Japan, Indonesia, French Polynesia and Australia. They are usually flat-backed and often called blister pearls because they form against the inside shells of oysters rather than within oysters’ bodies. Tahitian pearls are grown in French Polynesia and come in a range of colors, including gray and black with green, purple or rose overtones. Because of their large size and unique dark colors, they command very high prices. Also prized for their large size, white South Sea pearls are grown in Australia, Indonesia, the Philippines and other areas of the South Pacific.

Freshwater pearls come in various colors and are grown in bays, lakes and rivers primarily in Japan, China, Europe and the United States (Mississippi River). They are often irregularly shaped and less lustrous than saltwater cultured pearls, making them substantially less expensive. Types of freshwater pearls include Biwa pearls from Lake Biwa in Japan, irregularly shaped baroque pearls and the exceptionally small seed pearls.

Pearls that develop within the soft tissue of mollusks encounter little resistance and therefore grow to be round or "regular" in shape. However, pearls that become lodged in the muscular tissue of shellfish experience resistance, so they free-form into irregular, unusual shapes. These "Baroque" pearls are asymmetrical and are world-renowned for their naturally unique beauty. Baroque pearls were especially prized by jewelers during the Renaissance.

In China, cultured pearls come mainly from freshwater rivers and ponds, whereas Japan is famous for culturing pearls along their saltwater coasts. Black pearls can be found in the Gulf of Mexico and in waters off some islands in the Pacific Ocean. In the warmer waters of the South Pacific, larger oysters produce South Sea cultured pearls and Tahitian black cultured pearls. Cultured pearl industries are also carried out in Australia and equatorial islands of the Pacific. For thousands of years, natural pearls have been harvested from the Persian Gulf, the Red Sea and the coasts of India and Sri Lanka. Natural saltwater pearls are also found in the waters off Indonesia, the Gulf of California and the Pacific coast of Mexico.

Pearls have been treasured throughout ancient folklore and history. Aphrodite, the Greek goddess of love, considered pearls to be sacred. The Greeks prized the gems for their beauty and believed that wearing pearls would promote marital bliss and prevent newlywed women from crying. In ancient Rome, pearls were considered the ultimate symbol of wealth and status. The ancient Egyptians were buried with them and the Egyptian queen Cleopatra favored pearls immensely. It is said that while dining with Mark Anthony, she purposely dropped a pearl into her drink to demonstrate the wealth of her rule.

As early as 2000 B.C., pearls have been used as medicine in China, where it was believed to represent wealth, power and longevity. Pearls were also widely used as medicine in Europe until the seventeenth century.

Long ago, when pearls were not cultured and thousands of oysters had to be searched for only one pearl, the gems were important financial assets, comparable in price to real estate. Some European countries even banned all but nobility from the right to wear them. Medieval knights wore them in battle as a talisman against injury, while warriors in India encrusted pearls into their sword handles to symbolize the tears that swords can bring.

Today, the pearl is a universal symbol of innocence and purity. It is the birthstone for June and is considered the traditional gift for couples celebrating their 3 rd and 30 th wedding anniversaries. Many believe the gem gives wisdom through experience, quickens the laws of karma and cements engagements and love relationships. It is also considered to offer the powers of wealth, protection and luck.

The largest pearl in the world is approximately 3” long and 2” wide, weighing one-third of a pound. Called the Pearl of Asia, it was a gift from India’s Shah Jahan to his favorite wife, for whom he also built the Taj Mahal. Another famous pearl is called “La Peregrina,” or “the Wanderer,” and is considered by experts to be the most beautiful pearl in the world. Pear-shaped and measuring 1-1/2” in length, it is said that 400 years ago the pearl was found by a slave in Panama, who gave it up in return for his freedom. In 1570, the conquistadors sent the pearl to King Philip II of Spain. The pearl was passed to Mary I of England, who gave it to Prince Louis Napoleon of France, who sold it to the British Marquis of Abercon. After disappearing for a century, the pearl turned up once again in 1969 at a New York auction house. It was purchased by actor Richard Burton for his wife, Elizabeth Taylor.
