The composition feels geological rather than accidental, a frozen moment of subterranean order where multiple crystal voices speak in harmony, each distinct, yet inseparable from the whole. This natural cluster is defined by a striking structural dialogue between its main crystals. Two dominant smoky quartz prisms stand laterally, framing the specimen like sentinels, their elongated forms well defined and confidently terminated. Cutting through the visual centre of the cluster, a third crystal grows horizontally across the base, anchoring the composition and introducing a dynamic counterpoint to the vertical growth. Around these principal forms, several smaller secondary crystals emerge organically, reinforcing the sense of natural balance rather than crowding. The crystal habit is classic quartz, with well developed hexagonal prisms and natural rombohedral terminations. Growth striations are clearly visible along the prism faces, bearing witness to uninterrupted crystallisation within a stable hydrothermal environment. The terminations are natural and intact, showing no signs of polishing, reshaping or mechanical interference. Each face carries the subtle textures and micro irregularities expected of genuine, untouched quartz growth. Chromatically, the specimen displays an honest and elegant smoky quartz palette. The colour ranges from warm translucent brown to deeper smoky tones toward the terminations, with a clear vertical zonation that becomes more pronounced under directional light. This gradual darkening is characteristic of natural smoky quartz, produced by long term exposure to natural radiation within the host rock, rather than any artificial process. Light behaviour is one of the defining strengths of this cluster. Under frontal illumination, the prism faces reflect softly with a vitreous lustre, emphasising geometry and surface texture. Side lighting reveals internal depth and layered growth, while transmitted light activates the smoky zoning, allowing the internal architecture of the crystals to become visible without loss of contrast. The result is a specimen that remains visually engaging from every angle. The base of the cluster consists of compact quartz matrix, pale and slightly milky, providing both structural stability and a visual foundation that allows the darker smoky crystals to rise clearly above it. The cluster stands naturally without artificial support, reinforcing its integrity as a complete and well balanced mineral specimen. This is not a random aggregation of crystals, but a coherent geological structure shaped by time, pressure and chemistry. A cluster that communicates strength, balance and authenticity, offering both mineralogical interest and strong aesthetic impact.

This specimen stands out through its architectural composition, with dominant crystals arranged in a way that feels deliberate and resolved rather than chaotic. Collectors seeking Brazilian quartz that offers both visual impact and geological honesty will find this piece particularly compelling, as it represents the variety in a mature and dignified form rather than a purely decorative one. Lapidary Potential: This specimen is not intended for lapidary use. Any cutting would irreversibly destroy the natural cluster architecture, the interplay between vertical and horizontal growth, and the integrity of the terminations. Its true value lies in preservation, where its structural narrative, colour zoning and geological authenticity remain fully intact and ——————- 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
