A solitaire brilliant round shaped lab-created pretty pink sapphire gemstone 1.50 carat (ctw) sits in a crisp 14 karat white gold foundation while 46 sparkling lab grown diamonds 3/5 carats (ctw) form a double halo around the pink 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 origin.
