Every detail of this necklace—from the gleamy eighteen-karat yellow-gold wide-link chain (it’s crafted entirely by hand) to the sparkling diamond-studded heart outline pendant dangling from it—is, simply put, exquisite. At fifteen inches, it falls right at that between-the-collarbones sweet spot that’ll make friends with almost any neckline. And best of all, it’s versatile enough to wear with anything from a simple tee and jeans to your favorite LBD.
