In the realm of fine jewelry, it doesn't get much cooler than this Milanese label—helmed by verifiable style mavens Romy Blanga and Chiara Capitani. The Ninety necklace has been made in Italy from 18-karat yellow gold. Fastening with a custom-made hinge, the solid silhouette is accented with five signature squared charms, two of which are set with pavé diamonds.
