A solitaire pendant with a lab created cushion-cut blue sapphire (3.05 carats (ctw)) set into gleaming crisp 14 karat white gold setting and matching gold chain. Blue sapphire is the birthstone for September. This stunning pendant has beautiful lab-grown diamonds that sit above the blue gemstone. 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 the origin.
