Every girl has a bit of boho in her. But finding the right balance between hippie chick and hippie chic isn’t always easy, and when it comes to fine jewelry, the distinction had better be clear. No one wants her most precious finery mistaken for something from a St. Mark’s Place street vendor. H. Stern treads the line seamlessly. Its evocative cuff—an ode to a Grecian goddess—crafted from golden leaves and set with a bewitching diamond star is ethereal and elegant. Meanwhile, at Taffin, James de Givenchy plays opposites against each other in a diamond and citrine bracelet. He contrasts strands of polished diamonds with a very stately citrine for a sophisticated earthiness. Call it organic chemistry.
