MARLA AARON Sterling silver, 18-karat yellow and rose gold necklace

Marla Aaron often looks to industrial design when creating its contemporary fine jewelry. Made from a combination of sterling silver, 18-karat yellow and rose gold, this necklace has double-layered chains and is centered with the brand's signature carabiner-inspired 'Lock' - zoom in and you'll see the beautifully etched trundle is cast from rose gold.
