Cultured pearls from Australia, Indonesia, the Philippines, and Myanmar, are grown in the Pinctada Maxima mollusk. This shell one is called gold-lipped because of the color of the outer rim of its mother-of-pearl layer.
The black-lipped mollusk can produce a variety of cultured pearl colors. The color of the mother-of-pearl layer is often related to the color of the resulting cultured pearl’s nacre. - Courtesy A & Z Pearls and Tasaki Shinju Co
