The precious black pearls: have you heard of them? Read how to recognize them and how much they are worth ♦

To indicate something of value is said to be as precious as a pearl. But if the pearl is black, the value increases. In fact, not all pearls are white: the black ones (also known as Tahitian pearls) are very valuable. Actually they are not really black, but only darker in color, tending to gray. They are the fruits of the oyster Pinctada margaritifera (also called the Tahitian black pearl oyster), a mollusk that lives Indo-Pacific Ocean at the latitude of the Tropics. Black pearls are found in many shades, metal color, many shades of gray (who knows, maybe 50 ….), but also green peacock (they are considered particularly valuable), or to purple, like eggplant, and brown dark. The color depends on the minerals that the clam has ingested contained in the plankton, the food of oysters. In the cultivation of pearls, however, they are using dye or irradiation to improve or change their color. But do not expect to identify them: it is difficult to pick a natural pearl from a treated. As for gems, pearls also have values ​​(and costs) different.

The name of these pearls is, of course, linked to the place where they are grown, ie mainly around the islands of French Polynesia, near Tahiti.
