Today in the realm of pearl farming, my challenge is: my almost impossible mission is to find the rare pearl. Pearls are small balls made by some molluscs, mainly oysters. The term natural pearls or fine pearls should be used exclusively for pearls produced by molluscs without human intervention. The cultured pearls are obtained by introducing into the oyster a tiny grain of special irritating material. They are less resistant and less beautiful than natural pearls
The pearls are composed of calcium carbonate, just like the shells of oysters. Any foreign matter introduced into a living oyster causes a secretion of mother-of-pearl intended to drown the cause of irritation and which forms the pearl.
The Chinese were the first to obtain cultured pearls in the 13th century. At the end of the 19th century, the Japanese made it a prosperous industry. Since the manufacturing technique is prevalent in all Pacific islands.

Pearls have been used in jewelry since antiquity. They are called "the tears of Aphrodite". The value of the pearls is determined by their shape, brilliance, size and color.
The pearls are divided into eight basic shapes: round, semi-round, button, drop, oval, pear, baroque, ringed. Shine is the most important criteria for judging the quality of a pearl.The pearls are often white, sometimes with a cream or pink hue, but can also present a hue silver, champagne, peach, yellow, green, blue, brown, black. Black pearls are very expensive because they are very rare.
