Pinctada margaritifera

Pinctada margaritifera, commonly known as the black-lip pearl oyster, is a marine mollusk prized for producing high-quality black pearls. Found in tropical and subtropical waters, especially around French Polynesia, they reside on the ocean floor attached to reefs and rocks. The oyster creates pearls by secreting layers of nacre around a tiny irritant inserted during pearl farming. These pearls are valued for their rich dark colors and luster, making them highly sought after in jewelry. The species plays an important role in local ecosystems and economies, supporting sustainable aquaculture practices in affected regions.
