Here, a luminous one-carat pear-shaped diamond is set in a gleamy 14-karat gold east-west setting. It’s an unexpected—and undeniably pretty—piece. And it’s set on a 1.5-millimeter cable chain that adjusts to 16 or 18 inches, making it easy to work into a stack (which is how we like to style this pendant—though it more than holds its own solo). 14k gold, diamond 1 ctw Cable Chain: 1.5mm, 18" with 16" option
