Its chromatic expression is cool and refined, recalling glacial water captured in motion, with pale blue tones that remain crisp and luminous rather than dense or saturated. Under direct illumination, the crystal responds with remarkable vitality. Light penetrates deeply into the body, activating internal reflections and revealing layered growth features that shimmer softly within the prism. This optical behaviour gives the specimen a quiet brilliance, where brightness and transparency coexist in balance, allowing the aquamarine to glow from within rather than merely reflect light from its surface. The crystal exhibits a well proportioned prismatic form with clean vertical striations running along its faces, reinforcing its structural clarity and sense of upward movement. Several faces show natural emergence points from the original matrix, suggesting a multi directional growth history that adds geological interest and a rare sculptural complexity to the piece. These features do not disrupt the form, but instead enhance its individuality and natural presence. Subtle internal textures and fine inclusions are present, consistent with an untreated aquamarine of this origin. Rather than diminishing the stone, they contribute depth and authenticity, giving the crystal a dynamic internal landscape that becomes especially expressive when viewed against a dark background or under controlled backlighting. Aquamarines from Erongo are prized for their calm tonal range, architectural clarity and luminous internal structure. This specimen captures those qualities with restraint and elegance, offering a piece that feels both composed and alive, a natural study in light, form and geological time.

This specimen stands out through its ice blue tone and its ability to remain visually vibrant without relying on saturation or artificial enhancement. Collectors who value subtlety, structure and natural elegance will find this piece particularly appealing. Its compact yet confident form, combined with its luminous internal presence, makes it a refined addition to curated collections focused on African pegmatites, aquamarine varieties or prismatic crystal habits. Lapidary Potential: While the clarity and colour suggest selective lapidary possibilities, this specimen’s primary value lies in its preserved natural state. Any cutting would remove the defining architectural features and internal light pathways that give the crystal its identity. As such, its highest and most authentic expression is as a natural crystal specimen, where its geometry, ice blue colour and internal luminosity remain fully intact and appreciable. ——————- 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.
