14k Yellow Gold 4.9mm Italian Figaro Chain Necklace, 18 for $715.00

The name of this chain, Figaro, implies music. And the design of this 18-inch chain--three small square links alternating with one large oval link--certainly dances in the light, as if to a song. Cuts on the top, bottom, and corners of the links create endless angles that reflect light and give the chain its concave shape. The solid 14k gold ensures the chain’s strength and durability: pure gold is too malleable for jewelry and so is mixed with alloys of silver, copper, and zinc. The clasp is a lobster claw, which is easy to maneuver but also secure.
