“Anything I do tells a story,” says Coomi Bhasin, the designer behind the simultaneously luxe and brainy fine jewelry line, Coomi. Having launched in 2002, her previous collections have incorporated ancient Roman glass, or coins from the days of Alexander the Great. For fall, Bhasin’s one-of-a-kind rings, necklaces, and earrings combine diamonds, 20-karat gold, and arrowheads from the Paleolithic era. And the story she tells is one of evolution—both literal and artistic. “The skeleton is my favorite,” says Bhasin, referring to an arrowhead pendant she’s adorned with a gold and diamond iteration of Lucy—the oldest skeleton of human remains ever found on earth. “She’s very famous. And when her skeleton was found, there were some bones missing, so I recreated that,” offered Bhasin, adding that she’s embellished the back of the piece with three handprints, because handprints were “humans’ very first attempt at art.” Other highlights include arrowheads decorated with the skeleton of an ancient fish fossil, an interpretation of a bison cave drawing, and a deer running away from a slingshot—all done in diamonds, of course.
