Emerald, diamond, emerald, diamond. And so it goes for the entire (adjustable) length of this beautifully crafted, delicate gold ball-chain necklace. To break up the uniformity (and buck tradition just a bit), the diamonds are set in three-pronged settings while the emeralds are set in four-prongs, resulting in a brilliantly jagged fluidity. Wear solo or layer to your heart's content.
