Black pearl is a rare and valuable type of pearl known for its dark, lustrous appearance, often showcasing overtones of green, blue, or purple. Originating primarily from the black-lipped oyster (Pinctada margaritifera) in the lagoons of French Polynesia, especially Tahiti, these gems are also called Tahitian pearls. Types include baroque, round, drop, and circled black pearls, varying in shape and size.
Benefits: Traditionally, wearing black pearls is believed to bring protection, balance emotions, and attract prosperity, though these benefits are based on cultural beliefs and lack scientific validation.
