The ring in our campaign pairs a saturated blue centre stone with a halo of bright diamonds. When you shop a similar piece, look first at the sapphire’s body colour under natural light: even saturation usually reads more “expensive” than a patchy or greyish wash.

Next, tilt the stone slightly. A lively sapphire returns flashes of blue and violet; a dull or overly dark gem can look flat on the hand. The halo and split shoulders in this style add sparkle and protect the centre, but they also mean more cleaning — plan for a soft brush around the prongs.

If you love this silhouette, ask whether the sapphire is heated (common and stable) or untreated (rarer). Either can be beautiful; what matters is transparent grading and a setting that matches how often you wear the ring.
