Crisp and gleaming 14 karat white gold is the foundation for a stunning diamond engagement cluster ring featuring 3/4 carats (ctw G-H-I, SI1-SI2) of lab-grown sparkling diamonds. 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.
