A beautiful crisp 14 karat white polished gold and a blue topaz at its center 4/5 carat (ctw) across the top makes this a real men's ring that is simple and beautiful and makes a statement. This beautiful ring has 7/10 carats (ctw) of beautiful sparkling that support 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.
