A necklace changes a look the way nothing else does. Same outfit, different chain — entirely different woman.

Pendant necklaces in every theme — from meaningful religious pieces to playful initials to bold gemstone drops. Pearl strands, graduated or uniform, in cultured freshwater, Akoya, and shell pearl. Layering sets designed to work together without thinking about it. Bead necklaces with lapis, turquoise, and amethyst. Italian-crafted link styles with the weight and finish of pieces that cost twice as much. For over 70 years, Ross-Simons buyers have sourced necklaces from Italy, Asia, and beyond — building a collection that spans everyday essentials to fine pieces worth centering an entire look around. The one that completes yours is here.
