MARLA AARON Allstone Trundle Lock Ring + Inlay Charmed Box + Rondelle Strand 18-karat gold, malachite and sapphire necklace

All the pieces in Marla Aaron's collections are meant to be mixed and matched, but sometimes the designer does it for you - and beautifully so. Case in point, this necklace features a 19-inch chain knotted with vibrant malachite rondelles - the match those inlaid on the dainty yet functional 18-karat gold 'Charmed Box' perfectly. It's connected by a sapphire-encrusted 'Allstone Trundle Lock' that doubles as a ring. Each element is made by hand.
