A beautiful pear shaped lab-grown diamond center (5.80mm) 1/3 Carat (ctw H-I, SI1-SI2) is set in a striking gleaming 14 karat yellow gold foundation and a matching 18 inch gold chain. 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.
