A solitaire oval shaped lab-created green emerald gemstone 1.90 carat (ctw) sits in a crisp 14 karat white gold foundation while 48 sparkling lab grown diamonds 1/2 carats (ctw) form a double halo around the green gemstone. Emerald is the birthstone of 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.
