What is the oyster species used to grow Tahitian cultured pearls?

The oyster species used to grow Tahitian cultured pearls is Pinctada margaritifera, commonly known as the black-lipped oyster. This species is primarily found in the warm waters of the South Pacific and is renowned for producing pearls with unique colors, including peacock green, gray, and black.

The body of this oyster is distinguished by its dark shell, which contributes to the wide variety of pearl shades produced, making them highly sought after in the jewelry market. Pinctada margaritifera has the ability to form larger pearls compared to some other species, which adds to its desirability among pearl farmers and jewelry designers alike.

Other oyster species, such as Pinctada fucata, are primarily associated with the production of Akoya pearls, which differ significantly in size, shape, and color. Pinctada maxima is known for producing South Sea pearls, which vary in appearance from Tahitian pearls. Pinctada imbricata is less relevant in cultured pearl production, focusing more on other marine uses. Thus, Pinctada margaritifera stands out as the specific species integral to the cultivation of Tahitian cultured pearls.
