Classic earrings with marquise-cut blue-green aquamarine gemstones as the featured stone crafted from crisp gleaming 14 karat white gold. To complete the look of these stunning halo button earrings are 1/5 carats (ctw) of sparkling lab-grown diamonds in a halo formation. 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.
