Bluish-green sapphire occupies the boundary zone between blue and teal — a hue that reads with more blue content than pure teal, giving it the visual depth of blue with the distinctive color-shift character that teal is prized for. The cushion cut concentrates this dual-tone quality across the face, producing a richer, more saturated appearance than oval or round equivalents of the same weight.\u003c\/p\u003e\n\u003cdiv style=\"border: 2px solid #5b2c6f;
