According to ancient Chinese legend, the moon holds the power to create pearls, instilling them with its celestial glow and mystery. Pearls have been treasured for their lustrous, creamy texture and subtle iridescent reflections since the dawn of humankind.
Pearls are unique in the world of colored gemstones since they are the only gemstone formed within a living creature. Because natural pearls are so rare and difficult to recover from the ocean's depths, and, in fact, are prohibited from being harvested in most countries, man invented the technique of culturing sea and freshwater pearls from mollusks carefully seeded with irritants similar to those produced by nature. The painstaking effort of culturing is one of the most dramatic examples of man's quest to coax beauty from nature.
If you would like to see a natural pearl, your best chance would be to visit a museum.
Today, cultured pearls are grown and harvested in many parts of the world including the fresh waters of the Tennessee River. The majority of cultured pearls come from Japan, China and the South Pacific.
Cultured pearls come in many beautiful colors including: gold, yellow, champagne, pink, peach, lavender, gray and black. Cultured pearls come in many shapes and sizes, and can be acquired in both graduated and uniform strands. June birthdays and third and thirtieth anniversaries are celebrated with the gift of pearls.
Due to demand for perfectly matched white pearl strands, cultured fresh and saltwater pearls are often bleached to achieve a uniform color. They may also be polished in tumblers to clean and improve their luster.
Dyes, heat treatment, and irradiation are sometimes applied to produce a wide range of hues such as yellow, green, blue, purple, gray, and black in freshwater and Akoya cultured pearls. Some South Sea cultured pearls are bleached to lighten their hue, but most South Sea and Tahitian cultured pearls are not subjected to enhancements to create or improve their color.
Pearls require special care because they contain calcareous crystals that are sensitive to chemicals and acids.
