Its tone is not flat or uniform, but layered and expressive, shifting between luminous pinkish red highlights and deeper, more saturated crimson zones that create a natural internal dynamism. This is a diamond that captures attention instantly through colour alone. The red is energetic, rich and highly expressive, with a visual intensity that stands out even under subtle lighting. It carries a fresh, almost juicy luminosity, reminiscent of organic natural colour rather than artificial saturation. The crystal presents a compact and well balanced rounded freeform morphology, approaching a near spherical form. Its shape is elegant and harmonious, with smooth transitions between surfaces that give it a refined and visually pleasing presence from every angle. The surface is composed of dense micro crystalline textures, forming a complex network of small reflective planes. These structures interact strongly with light, producing scattered flashes of adamantine lustre across the stone. Unlike polished diamonds, the brilliance here is fragmented and dynamic, creating a constant interplay of sparkle and depth. Colour distribution is naturally irregular, with certain areas displaying stronger concentration of red, while others soften into lighter tones. This variation enhances the perception of depth, making the diamond feel almost internally illuminated. Transparency remains limited, yet this contributes positively to the visual identity of the piece. Light is absorbed and remitted across the surface rather than transmitted, intensifying the richness of the red colour and reinforcing its bold character. The lustre is distinctly adamantine, expressed through multiple micro reflections that give the surface a lively and energetic appearance. Combined with its rounded form, this creates a strong three dimensional presence despite its compact size. Recovered from the alluvial deposits of Lunda Norte in Angola, this specimen retains its complete natural integrity. It has not been cut, polished or treated, preserving both its structure and its exceptional colour in their original state. This is not simply a coloured diamond. It is a concentrated expression of natural red, captured in one of its most rare and compelling forms.

Collector’s Interest: Red diamonds represent one of the rarest and most sought after colour categories in the world of natural diamonds. Their presence is often subtle in faceted stones, but in raw specimens such as this, the colour appears more organic, more expressive and far less constrained. This piece stands out through its combination of intensity and form. The rounded morphology enhances the way light interacts with the surface, while the saturated red tones create an immediate emotional response. For collectors, this is not just a specimen of rarity, but of character. It offers a raw and authentic expression of one of nature’s most elusive colours. Lapidary Potential: Although cutting could theoretically be considered, it would result in significant material loss and would remove the surface features and colour distribution that define the identity of this specimen. In its current form, the diamond is exceptionally well suited for use in jewellery as a distinctive centrepiece, particularly in bespoke rings or pendants where its natural shape and vivid colour can be fully appreciated. Its highest value lies in preservation, either as a collector’s specimen or as a unique and organic element within high end jewellery design. ——————- 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
