Black Mother of Pearl





Pinctada margaritifera oyster

Black Mother of Pearl shells, the dark, silky gems from the South seas are cultured in the lagoons of Tahitian and Cook Island atolls. The Pinctada margaritifera oyster (or Black-lip mother of Pearl) produces a unique dark lustrous free-form or marbe pearl. The lustrous dark-lipped shell must be the ocean's black beauty. An eye-catching look for jewellery, laminate, tiles and tumbled pieces.
