heirloom pieces): this short, dainty chain necklace, made from 14k gold-plated sterling silver. Hint: It's oh-so-fun to add one or two of our demi-fine nautical charms. Want to keep your jewelry looking like new? We recommend removing it before showering or exercise, and putting it on after applying hair products or perfume. To clean your pieces, polish them with a soft, dry cloth—and when not wearing, store them in a pouch or jewelry case.
