Founded by Tahiti native Maire-Nui Yao, who immigrated to Honolulu in 2003, Maire-Nui Tahiti Pearls proffers handmade baubles adorned with black Tahitian pearls. Inspired by her exotic homeland, the designer imbues every artisan piece with the spirit of the island and the souls of champion synchronized-swimming tiki gods. Bedeck the graceful neck of a loving spouse or loyal steed with the Ateni ($75), a sterling-silver necklace punctuated by Tahitian and freshwater pearls, or extend a token of appreciation with the masculine Tautiare ($85), a single 11-millimeter black pearl elegantly strung on a knotted leather thong. Pearl-festooned bracelets, such as the crystal-accented Ranitea ($65), add glamor to bare wrists, and a pair of Tevei earrings ($85), two 9-millimeter black pearls hung on 14-karat gold-wire loops, dangle elegantly from lobes.
