Jacquie Aiche - A single drop of faceted blue tourmaline lends a beguiling finish to Jacquie Aiche's 14kt rose-gold earring. It's handmade in the designer's LA-based workshop with a fine chain and three bezel-set white diamonds which total 0.09ct, and secures with a post-back fastening. Style it as a solo accent to a bold day dress with your hair in a neat updo to ensure it pulls focus.
