Black pearls are primarily found in the waters of the South Pacific, specifically in the lagoons and atolls of French Polynesia, particularly around the islands of Tahiti. They are produced by the black-lipped oyster (Pinctada margaritifera) and are highly valued for their unique color and luster. Other locations that produce black pearls include the Cook Islands and the Marquesas Islands.
