Tahitian pearls, grown around Tahiti and French Polynesia, display a shimmering orient or overtone that is green, blue, pink or violet in color. These orient colors are in striking contrast to their silver to black body color and are sometimes given specific names (e.g., deep green is called fly wing; peacock is used for the combination of green and pink; eggplant is a dark toned body color combined with pink).
