Rangiroa, the largest atoll in the Tuamotus, is the center of the thriving French Polynesian pearl industry. Paul Gauguin passengers can set sail over the blue waters of the lagoon to a pearl farm where they can learn about the complex process of cultivating pearls. After learning how to evaluate the quality of a pearl like a master jeweler, you’ll be able to purchase black pearls direct from the sea. Due to the variety of shapes and colors, black pearls are known for their versatility to fit into any jewelry setting—calling them black doesn’t accurately capture the range of colors of Tahitian pearls, with shades of green, pink, blue, and other hues. You can take the unset souvenir back home to add a unique piece to your collection—one that will forever remind you of an unforgettable tropical getaway.
