An unheated sapphire in a vivid teal, where bright green and saturated blue share the stone in open contrast. In person it is brilliant and full of motion: one side of the stone glows a fresh, warm green while the other deepens into cool blue-teal, and as it turns the two tones sweep across the face and trade places, with juicy blue sparks flashing through the crown. The compact, well-proportioned oval keeps it bright edge to edge, with no pale center. It is eye clean, so the shifting color reads clearly. IGI has examined the stone and found no indications of heating; this teal is entirely natural.
