Not since the rocking Eighties and Prince’s ode to the royal color has purple had such a standout moment—and jewelers are taking notice. Eclat, for one, creates high drama with a one-of-a-kind titanium butterfly brooch. Sprinkled with nearly 500 diamonds, the fuchsia winged piece is an artsy nature study. Meanwhile, Tiffany’s multistranded beaded spinel necklace in subtle shades of lavender and rose is a sophisticated example of bohemian appeal. And Cartier’s classically masculine Roadster watch, modeled after automobiles from the Fifties and Sixties, receives a feminine touch with a violet satin band and an iridescent mother-of-pearl face. Talk about a purple haze.
