About the Item

Gemstone Details: Faceted Bicolor Tourmaline Weight 4.0 carats Color Blue with Deep Navy Blue Dimension 12.6 x 7.9 x 4.6 mm Origin Kunar, Afghanistan Treatment None Shape and Cut Emerald Transparency Transparent Clarity Natural inclusions and internal characteristics typical of natural tourmaline. Lab report will be made on demand The stone has been photographed in good natural lighting to show the actual color and texture. Description: This remarkable natural bicolor tourmaline displays an extraordinary transition between vivid neon aqua blue and deep midnight blue, creating a dramatic two-tone effect rarely found in nature. Cut in a refined emerald shape, the gemstone showcases crisp step facets that emphasize its striking color zoning and elegant crystal structure. The color profile is particularly captivating, featuring a bright electric aqua-blue at one end that gradually deepens into rich navy and midnight blue tones through the center. This natural blue-on-blue color separation creates exceptional visual depth, reminiscent of tropical lagoons fading into the deep ocean. Unlike many tourmalines that display greenish undertones, this gemstone is distinguished by its pure blue character, making it highly desirable among collectors and connoisseurs. Sourced from the legendary pegmatite deposits of Afghanistan, this tourmaline originates from one of the world’s most respected localities for fine gem-quality tourmaline. Afghan tourmalines are celebrated for their vibrant saturation, unique color combinations, and rarity in the international gemstone market. Its elegant emerald-cut proportions make it an excellent choice for custom jewelry designs. This gemstone would create a stunning centerpiece in a statement ring, pendant necklace, or pair beautifully with diamonds in a bespoke fine jewelry setting. The vivid blue shades are particularly enhanced when set in white gold or platinum, while yellow gold creates a striking contrast. Tourmaline is the official birthstone for October and is treasured for its remarkable diversity of colors. In metaphysical traditions, blue tourmaline is associated with mental clarity, truthful communication, self-expression, and emotional balance. Many believe it encourages calm energy, inner wisdom, and confidence in decision-making. Whether acquired as a collector’s gemstone, an October birthstone gift, or a centerpiece for a custom jewelry creation, this Afghan bicolor blue tourmaline offers a rare combination of vivid color, natural beauty, and exceptional individuality.
