Dark Pearls From Atoll Lagoons

Tahitian pearls are cultured in the black-lip pearl oyster, Pinctada margaritifera, mostly on the atolls of the Tuamotu and Gambier islands in French Polynesia. Clear, calm lagoons and plankton-rich water suit the oysters. Pearls are one of the territory's leading exports.

Pearl culture begins with grafting. A skilled technician places a small bead, often cut from freshwater mussel shell, inside the oyster along with a piece of mantle tissue from a donor. The tissue forms a sac that coats the bead in nacre, layer by layer, over about 18 months to two years.

Despite the name, Tahitian pearls are not only black. They come in grays, blues, greens and aubergine, and peacock green overtones are especially prized. Pearls are graded by size, shape, luster, surface and color, and a healthy oyster can be grafted again to grow another pearl.
