This chain necklace alternates between fancy yellow diamonds and white diamonds (G color, VS2-SI1 clarity), each measuring 1.4mm and weighing .0125 carats, bezel-set along an 18-inch chain of platinum and 18 karat yellow gold in a "diamonds by the yard" style. The two-tone metal construction plays perfectly with the alternating diamond colors—yellow and white stones creating a pattern along the length.
