Its form is immediately striking: a naturally preserved hexagonal prism crowned by a sharply defined six sided termination, intact and unforced, as nature intended. The geometry feels deliberate, almost architectural, with each face meeting the next in precise alignment, conveying a sense of order that is both calming and commanding. Within the crystal body, perfectly vertical internal growth lines rise in parallel ascent, visible in select zones where light penetrates deeply into the structure. These internal striations are not surface markings but growth records suspended within the crystal itself, tracing the aquamarine’s slow and uninterrupted formation. They give the specimen a remarkable sense of vertical continuity, as if the crystal were drawn upward in a single, confident motion. The colour is refined and restrained rather than overt. A cool, glacial blue resides within the crystal, subtle yet unmistakable, intensifying under direct illumination. When exposed to focused light, the interior awakens with luminous clarity, releasing soft flashes and icy reflections that travel along the vertical architecture of the crystal. The result is a sensation of internal movement, as though light itself were flowing through frozen water. This aquamarine does not rely on saturation alone for impact. Its presence is defined by balance: between clarity and structure, between softness of colour and strength of form. It stands as a museum grade specimen not through excess, but through coherence, integrity and the quiet authority of natural precision.

This specimen appeals to collectors who value formation integrity, geometry and optical behaviour over sheer colour intensity. Its internal vertical growth lines and luminous response to light give it a distinctive identity, placing it firmly within the realm of museum grade aquamarine specimens. Lapidary Potential: With nearly sixty carats of material and zones of excellent internal clarity, this aquamarine offers significant lapidary potential. The crystal’s proportions allow for the possibility of producing one or more gemstones of notable size, while preserving the refined blue tonality characteristic of high quality aquamarine. That said, the integrity of the natural termination and internal architecture presents a compelling case for preservation, leaving its future to be defined by intent rather than necessity. —————— 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
