Are colored pearls man made

Colored pearls can be both natural and man-made. Natural colored pearls occur when oysters produce nacre in various shades due to factors like water conditions and the type of irritant. Man-made or cultured pearls, on the other hand, are created by intentionally implanting a nucleus into an oyster, and they can be dyed to achieve specific colors. Thus, while some colored pearls are natural, others are artificially produced.
