A marquise-cut light blue sapphire, set east-west, is paired with a marquise diamond just below, the two stones meeting in the signature MG "Muse" setting. With 1.39 total carats of sapphire and .49 total carats of diamond, soft blue and bright white sit side by side, neither one framing the other. It's a compact, airy pairing with a cool, luminous tone.
