Bluish-green tourmaline is a gemstone with a vibrant, cool hue that falls between blue and green on the color spectrum. The color can range from a soft, pastel teal to a deeper, more intense blue-green. The stone often exhibits a pleasing, transparent quality with excellent clarity, though some stones may display slight inclusions that add character. Bluish-green tourmaline is prized for its captivating, refreshing appearance and is often used in fine jewelry. It is sometimes called "indicolite" when the blue tones are more prominent, or "paraiba" if it displays a particularly vivid blue-green color with unique fluorescent qualities.
