The halo ring is a setting that encircles a center stone in a collection of round pavé or micro-pavé diamonds (or faceted color gemstones). These pavé stones flash with light and focus attention back on the center stone to create interest and draw people’s gaze to your ring. A high-carat center stone looks enormous in a halo setting. And a quarter-, third- or half-carat stone can look, by some estimates, as much as a half or a carat larger. So no matter what your budget, a halo ring gives you a bigger bang for your buck.
