Messika's 'Move' collection is a favorite of Gigi Hadid - in fact, the model is such a big fan, she even collaborated with the brand to create her own version of the signature lineup. Recognized by its bezel-set diamonds that slide freely in a slender pavé-encrusted setting, this necklace is handcrafted from 18-karat white gold and stippled with four more shimmering stones along its delicate chain. 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.
