This crystal rock necklace ($128) at J. Crew is a bold statement piece. It was assembled completely by hand with oversize stones. We love the contrast of the stones’ heft with the beautiful luminosity of the faceted glass. Equally at home peeking from beneath a button-down shirt or grazing the neckline of a favorite dress, you’ll wear this necklace again and again. Round glass stones on a hematite-plated (gunmetal) or copper-and-gold-plated (copper) brass-and-steel chain. Signature spring clasp closure with connector ring. Lovely!
