Valérie Messika often incorporates movement into her jewelry designs, allowing the stones to really catch the light and sparkle. Handmade from 18-karat gold, this necklace is strung with a polished charm inlaid with a free-floating diamond and surrounded by a shimmering halo that's also encrusted with the stone. Layer it with similar styles from the brand. Each Messika piece comes with a two-year warranty, which is activated 28 days after purchase. To receive an additional year’s warranty, register your piece on Messika’s website.
