Its presence is immediately defined by a striking white body colour that appears luminous rather than opaque, capturing and reflecting light with remarkable clarity. The crystal presents a compact yet well developed rounded freeform morphology, with softly irregular contours that create a natural and balanced three dimensional form. Despite its organic structure, the piece carries a strong visual coherence, appearing both raw and refined at the same time. Its colour is distinctly white, with no visible colour bias, giving it a clean and neutral appearance that enhances its brilliance. This absence of tonal interference allows light to interact freely with the surface, producing a crisp and highly reflective visual effect. The surface is composed of natural micro crystalline textures and subtle growth features that scatter light dynamically across the stone. These micro structures create multiple reflective points, generating sharp flashes of adamantine lustre that shift continuously as the viewing angle changes. Under backlighting, the diamond becomes even more expressive. Light penetrates the outer layers and activates the internal structure, increasing brightness and revealing additional reflective depth. This interaction reinforces the impression of a luminous, almost radiant body, where light is not only reflected but also partially diffused within the crystal. Transparency is moderate, allowing enough light interaction to enhance brilliance while maintaining the solid visual presence of the stone. The result is a balanced optical behaviour where reflection and internal glow coexist. Recovered from the alluvial diamond fields of Lunda Norte in Angola, this specimen remains completely natural, unpolished and untreated, preserving its original morphology and optical character. This is not simply a white diamond. It is a pure expression of light, structure and natural formation, presented in its most authentic state.

Collector’s Interest: White diamonds in rough form offer a unique perspective on the fundamental qualities that define diamond as a material. Without the influence of cutting or polishing, the focus shifts entirely to natural structure, surface behaviour and intrinsic optical properties. This specimen stands out through its clean colour and strong light interaction. The absence of colour allows the brilliance and texture to take centre stage, creating a piece that feels both minimal and powerful. For collectors, it represents a refined example of natural diamond purity, where simplicity becomes its greatest strength. Lapidary Potential: The stone could be considered for cutting due to its clean colour and balanced morphology. However, any intervention would remove the natural surface textures and growth features that define its current identity. In its present state, it offers excellent potential as a natural centrepiece in jewellery, particularly in bespoke rings or pendants where its brightness and organic form can be fully appreciated. Its highest value lies in its preservation, maintaining the integrity of its natural structure and optical behaviour.. ——————- Shipping and Handling: All orders are shipped by Portuguese National Post and UPS. • Dispatch time: within 1 to 3 business days after payment confirmation to Catawiki • Transit time service: between 2 to 5 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
