Its proportions are immediately striking: exceptionally tall, remarkably thin, and perfectly disciplined in its geometry, the crystal commands attention through elegance rather than mass. At 31 mm in height, it belongs to a rare category of elongated indicolites whose visual power lies in height, continuity, and internal architecture. The chromatic journey begins at the base with a vivid, luminous green, fresh and vibrant, carrying a sense of energy and renewal. From this foundation, the colour slowly deepens as it climbs, transitioning through progressively darker green tones until it reaches a rich, saturated forest green near the termination. This vertical gradient unfolds naturally and uninterrupted, creating a seamless chromatic ascent that feels intentional, almost orchestrated by geological rhythm rather than chance. Within the core of the crystal, a remarkable internal phenomenon reveals itself. Dark, linear inclusions rise from the base and travel upward through the central body, like shadowed currents moving within a column of light. These slender black shafts do not disrupt the crystal’s clarity; instead, they introduce depth, contrast, and a dramatic sense of inner movement. The effect is evocative of deep-rooted forces rising through a translucent medium, lending the specimen an almost calligraphic internal structure that becomes more apparent under focused light. Surface striations run cleanly along the length of the prism, reinforcing the crystal’s verticality and guiding reflections upward. The termination is naturally formed and well preserved, gently sealing the chromatic progression at its peak. Under controlled lighting, the crystal displays a subtle internal glow, where light traces the vertical channels and briefly illuminates the darker internal features before dissolving into the deeper green tones above. Indicolites of this calibre are characteristic of the high altitude pegmatites of northern Pakistan, a region renowned for producing some of the world’s most refined and structurally elegant tourmalines. This specimen exemplifies that heritage through its exceptional height, disciplined form, and expressive internal architecture. It is not merely a tall crystal, but a complete vertical narrative of colour, structure, and geological intent. This is a specimen that does more than complement a collection. It defines a vertical axis within it.

The presence of vertical dark inclusions adds a rare structural narrative that elevates this piece beyond standard colour zoning specimens. Its proportions, origin, and internal character make it particularly appealing to advanced collectors focused on vertical crystals, Pakistan pegmatite material, and specimens with strong visual identity. Lapidary Interest: Due to its exceptional height and slender architecture, this crystal is best preserved as a mineral specimen. However, its internal features and colour gradient make it an outstanding subject for optical study, macro photography, and high end mineral presentation. Any lapidary consideration would compromise the very qualities that define its rarity and aesthetic strength. ————— Photography and transparency: All photos were taken under controlled light conditions, carefully selected to reproduce the most accurate natural colour of each specimen. No filters, colour enhancement, or artificial saturation were applied. The lighting setup uses a calibrated 5500K light source, which replicates neutral daylight and reveals the true tones and clarity of the mineral. Under weaker or more yellow indoor lighting, colours may appear slightly different, which is normal and expected. The purpose of this setup is to present each specimen exactly as it appears in balanced natural daylight, allowing buyers to appreciate its authentic colour and lustre without distortion. Identification and ethics: All specimens offered are guaranteed natural and as described. Their origin and mineral identification are provided with the most accurate and reliable information available. Every effort is made to ensure that each piece is presented with full transparency, avoiding any misleading details regarding its nature, treatment, or provenance. Shipping and handling: Orders are carefully prepared, with each stone individually protected and placed in a secure rigid box to ensure safe delivery. Shipments are made within 1 to 3 business days after payment confirmation, always with a tracking number provided to the buyer. Each order is handled with professional care from selection to dispatch, ensuring a smooth and trustworthy process. Customs and import taxes: Any customs duties, import fees, or local taxes applied by the destination country are entirely the responsibility of the winning bidder. These charges are not included in the auction price or shipping cost and are determined by the buyer’s local authorities. Guarantee and resolution: Customer satisfaction is a priority.
