The sister designers behind jewelry line Anndra Neen are upping the ante on their signature brass, silver and copper creations. For the first time, Phoebe and Annette Stephens introduced color and stones into their collection this spring. The centerpiece: this lapis Calder-esque collar. The earthy blue accents play beautifully off the distinctive geometric silhouette for an artful contrast of modern and organic. Give this statement piece the display it deserves—wear it solo with a minimalist ensemble.
