Chopard often looks to nature for inspiration - the house's latest 'Happy Spirit' collection is designed to mimic the way water ripples after a disturbance. Crafted in the brand's Swiss atelier from 18-karat white gold, this necklace has a trio of concentric rings, with the smallest illuminated by three signature floating diamonds. Aside from the delicate chain, everything else is set with twinkling precious stones, too.
