Messika's necklace is part of the brand's 'Move Romane' collection, which showcases tiny diamonds sliding freely on their own. Cast from 18-karat rose gold, it's strung with a disc-shaped pendant traced with three rows of shimmering pavé stones. It'll look so elegant worn with a silk camisole. 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.
