Tahitian pearls or black pearls are the only pearls that are truly black. These pearls come from the Tahiti-Polynesian islands. The black pearl is not only rare, exotic and breathtakingly beautiful, it is an integral part of the Polynesian economy and lifestyle. The islands are the leading exporters of fine black cultured pearls in the world.

Black pearls are pearl concretions that are concealed inside the black-lipped Pinctada Margaritifera pearl oysters. These pearls come in many shapes, diameters, qualities and several natural shades ranging from pale gray to jet-black. Black pearls for making necklaces and other jewelry are chosen with care many pearls that do not satisfy the criteria are rejected. The chosen pearls must not reveal the nucleus or the seed of the nucleus.

Tahitian pearls are grown in large black-lipped oysters in the salt waters of Tahiti. The natural black color pearl is particularly famous and most desired. Universal colors are black, gray, blue and peacock green. Perfectly round Tahitian pearls with a nearly flawless surface and remarkable luster are considered the highest quality and best for making necklaces. Black pearl necklaces are made in various shapes and sizes.

The black-lip mother-of-pearl specially found in the waters of French Polyne secretes a black pigment. This pigment ejaculated by the mollusk gives a rich color to the pearl ranging from deep black to gray to light silver. Shades of green, blue and pink can also be found. The saltwater oysters are big, sometimes almost the size of a dinner plate, and produce luxurious pearls ranging from 8 to 18 mm in size. Prices range from $100 for a small pearl of average quality up to $10,000 for a round pearl of perfect quality with a diameter of 18mm. However, black pearls are very rare compared to ordinary white pearls. If one is looking to buy these exquisite pearl necklaces, the online market offers a wonderful array of black pearl lengths. However one must shop carefully and purchase pearls only from trusted sellers.
