David Yurman - Cable 18-Karat Gold Diamond Ring - 5

Cable is the river that runs through everything I do, says David Yurman of his signature design - the motif has been a brand staple since the '80s. Cast from 18-karat gold, this ring is pavé-set with a row of twinkling diamonds. It's dainty enough to be stacked and layered, but also makes quite the impact on its own.
