Description: A slender and highly expressive elbaite tourmaline crystal displaying a striking vertical colour transition, where a cool blue to greenish blue body rises into a delicate salmon pink termination. The crystal develops as a fine elongated prism with a well defined geometry and a strong sense of vertical continuity. The lower section is dominated by a serene blue tone, slightly shifting into greenish nuances depending on the angle of light. This zone presents moderate transparency, allowing internal structures to be observed while maintaining a soft and balanced saturation. As the crystal approaches its upper section, a narrow transitional band appears, lightly infused with yellowish tones that act as a subtle bridge between the two dominant colour phases. Above this, the colour evolves into a warm salmon pink termination, creating a refined and visually elegant contrast against the cooler base. This colour zoning reflects a clear variation in the chemical environment during growth. The blue lower body suggests iron rich conditions, while the upper pink termination indicates a later stage enriched in manganese. The presence of the transitional band reinforces the continuity of crystallisation rather than an abrupt interruption, preserving the integrity of the growth sequence. The termination is natural and slightly uneven, preserving its original crystallisation surface. Minor irregularities and micro textures are consistent with natural formation and contribute to the authenticity of the specimen. Longitudinal striations are visible along the prism faces, running continuously from base to termination and documenting stable growth conditions. Internally, fine inclusions and linear features are present, aligned with the crystal axis and fully coherent with pegmatitic origin. Light interaction enhances the visual complexity of the piece. The blue body transmits light with a calm depth, while the salmon termination captures and diffuses it in a softer and warmer manner. This contrast creates a balanced interplay between cool and warm tones, giving the crystal a refined visual rhythm. This specimen offers a clear and elegant example of chromatic evolution within a single crystal, combining structural clarity, colour contrast and natural growth integrity in a compact and well preserved form.

The contrast between blue and salmon tones is both aesthetically appealing and mineralogically significant. Its value lies not only in its colour combination but in the clarity of its zoning and the preservation of its natural form. It is a specimen that communicates its formation process with precision, making it particularly attractive for collectors focused on crystal growth and geochemical transitions. Lapidary Potential: Any cutting would remove the defining relationship between the blue body and the salmon termination, which is the central identity of the specimen. In its current state, the crystal retains its full natural expression, where structure, colour and growth history remain intact and fully observable. ————- 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. In the unlikely event of an issue such as loss, damage, or discrepancy, please contact us promptly through Catawiki’s messaging system. 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
