**Complimentary Specimens** As a gesture of appreciation, winning lots with a final hammer price above €50 will include one small additional mineral offered entirely free of charge. ————— Description: Standing slender and composed, this striking green Tourmaline crystal rises with a quiet, almost botanical elegance, its vertical form evoking the silhouette of a mineral cactus shaped by time and pressure rather than by design. From the base, the crystal opens in a vivid lime to grassy green, luminous and energetic, with a freshness that immediately responds to light. This green body is clean and expressive, carrying a natural vibrancy that feels alive rather than static. As the eye travels upward along the crystal’s length, the colour deepens subtly, gaining density and maturity before culminating in a dramatic black cap termination. This dark crown is not abrupt nor intrusive; instead, it reads as a natural chromatic conclusion, grounding the crystal visually and giving it a strong sense of vertical resolution. The contrast between the luminous green shaft and the dark termination creates a powerful compositional balance, both graphic and refined. The colour zoning follows the growth axis with clarity and intent, presenting a coherent vertical narrative rather than a fragmented transition. This natural chromatic architecture speaks to a stable and uninterrupted growth environment, allowing the crystal to develop both its colour intensity and its elegant proportions without distortion. The prismatic habit is sharply defined, with crisp longitudinal striations running cleanly along the faces. These growth lines reinforce the crystal’s vertical rhythm and enhance its sculptural presence, lending it an architectural quality despite its slender dimensions. Internally, delicate natural features add depth and texture without compromising the crystal’s overall translucency, contributing to a refined and highly collectible character. What ultimately defines this specimen is its composure. Nothing feels accidental. The proportions are assured, the colour transitions intentional, and the form disciplined. It is a crystal that commands attention through contrast and coherence rather than excess, a restrained yet striking expression of tourmaline growth from one of the world’s most respected localities.

Specimens from the Alto Ligonha region are particularly prized for their balance of colour intensity and structural refinement, and crystals of this clarity and compositional strength are becoming increasingly difficult to source. This piece appeals strongly to collectors who value contrast, natural geometry and expressive growth habits within a compact format. Lapidary Potential: While the crystal’s colour and transparency could suggest theoretical lapidary interest, its true value lies in its intact form and dramatic colour contrast. Any cutting would remove the defining black cap and disrupt the vertical narrative that gives this specimen its identity. As such, it is far more compelling preserved as a natural crystal, where its full geological and aesthetic story remains visible and intact. ————- Shipping and Handling: All orders are shipped by Portuguese National Post. • Dispatch time: within 1 to 3 business days after payment confirmation to Catawiki • Transit time with CTT service: between 5 to 7 business days within europe and worldwide, depending on destination national post. • A tracking number is always provided Photography and transparency: All photographs are taken under controlled lighting conditions using a macro lens, carefully selected to present each specimen as accurately as possible. No filters, colour enhancement, or artificial saturation are applied. The lighting setup uses a calibrated 5500K light source, replicating neutral daylight to reveal natural tones, surface features, and internal characteristics. Under warmer or weaker indoor lighting, colours may appear slightly different, which is normal. The purpose of this photographic process is documentation and representation, not visual enhancement. Images are intended to reflect the specimen faithfully as it appears under balanced natural light conditions. Identification and ethics: All specimens offered are natural and described to the best of our knowledge, based on direct sourcing, professional experience, and information provided by trusted suppliers working at the origin. Every effort is made to ensure transparency and accuracy regarding identification, locality, and general characteristics, avoiding misleading statements about treatment, provenance, or nature. 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 important.

Each case is handled individually and fairly, with appropriate solutions offered when justified. Appreciation and commitment: We sincerely thank you for your trust. Our work focuses on careful selection, accurate representation, and respectful presentation of mineral specimens with character and interest. Each piece is chosen for its individual qualities rather than speculative or financial considerations. We aim to provide a transparent, reliable, and consistent experience for collectors at all levels. With gratitude, GemPulse Minerals
