Tahitian pearls are exotic, luxurious pearls that are cultivated in warm salt water in French Polynesia, primarily  around Tahiti. Since production is limited to a specific region it adds to the rarity of Tahitian pearls. Referred to as black pearls because they come from the black-lipped oyster, the pearls are distinctive and have a natural dark coloration.  However, Tahitian pearls actually come in a wide array of overtones including peacock, green and purple iridescent, silver, charcoal, aubergine, and blue. High-quality Tahitian pearls have a rich luster, a deep mirror-like shine, that reflects light and enhances the dramatic colors. This makes Tahitian pearls both natural and rare.

Cultivating Tahitian pearls is a time-consuming process as only one pearl is grown in each oyster. The process takes at least 18 to 24 months and many oysters do not survive or produce high-quality pearls. Other qualities that make Tahitian pearls rare and unique include the shape - round, baroque, oval, button, teardrop, and circular - and the size of the pearl.
