A beautiful cushion-cut shaped natural 6mm lab-created green emerald gemstone is set in striking crisp 14 karat white gold and surrounded by a halo of sparkling lab-grown white diamonds 1/4 carat (ctw) and includes a matching 18 inch 14 karat white gold chain. Green emeralds are the birthstone for the month of May. Lab grown diamonds are man-made diamonds that are chemically, physically, and optically identical to diamonds originating from nature. Both have the same chemical composition and atomic structure, producing the very same durability, fire, and sparkle, the only difference is origin.
