The tone recalls the colour of polar shallows where sunlight penetrates cold, mineral rich waters, producing a clean and vibrant hue that feels crisp rather than saturated. The balance between blue and green is precise, with neither element overpowering the other, resulting in a refined aquatic colour with natural luminosity. When viewed under direct backlighting, the diamond reveals a notable increase in chromatic intensity. The blue component becomes more pronounced, while the green undertone remains present as a soft modifier, giving the stone a vivid internal glow. Rather than flattening, the colour deepens and gains dimension, creating a sense of internal movement and transparency that enhances its visual presence despite the small size. Recovered from the alluvial deposits of Lunda Norte, Angola, this diamond reflects the geological character of one of Africa’s most respected diamond regions. Formed within ancient river systems and preserved through long term sedimentary processes, alluvial diamonds from this locality are known for their natural balance, chromatic stability, and authentic surface character. These stones are shaped by nature rather than machinery, retaining individuality and integrity in their original state. The crystal remains completely natural, presenting a compact rough form with irregular planes and softly rounded edges shaped by geological forces alone. Natural growth textures scatter light across the surface, producing subtle flashes and highlights instead of polished reflections. Even without cutting, the adamantine lustre is clearly visible, reinforcing the inherent nobility of diamond in its raw form. This piece embodies a quiet tension between rugged formation and refined colour. Untreated and unaltered, it communicates value through authenticity, origin, and colour behaviour rather than size. It is a diamond that allows geological history and natural colour to speak directly to the observer.

This piece offers collectors an authentic example of Angolan diamond heritage, combining natural colour, raw form, and geological identity. Its untouched state and expressive behaviour under light make it especially appealing to collectors focused on natural coloured diamonds with strong character and provenance. Lapidary Potential: The consistent bluish green colour and its pronounced response to backlighting suggest good colour retention potential in a carefully planned cut, even at small scale. The crystal’s natural morphology allows observation of growth orientation, providing valuable insight for colour focused lapidary decisions. Whether preserved in its natural state or considered for selective cutting, this diamond presents meaningful lapidary potential rooted in colour behaviour, structure, and authenticity rather than size alone ——————- 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
