Its body tone reveals a vivid interplay between blue and green, where neither dominates fully, creating a chromatic balance that shifts subtly as light moves across the surface. Under direct illumination, the colour intensifies rather than flattens, producing a luminous aquatic glow that appears to rise from within the crystal rather than sit on its exterior. This diamond originates from Lunda Norte, Angola, a region internationally recognised for its historic alluvial diamond deposits and for producing some of Africa’s most stable and expressive natural colours. The diamonds from this area are celebrated not for artificial brilliance, but for their geological honesty, formed over vast spans of time and transported gently by ancient river systems. This slow natural concentration process often preserves exceptional colour integrity, allowing hues like greenish blue to remain vivid and consistent even in small crystal forms. The crystal itself retains a fully natural morphology, shaped exclusively by geological forces. Rounded growth, irregular planes, and raw structural contours speak directly to its untouched origin. Across the surface, natural growth textures and crystalline relief interact with light in a way polished stones cannot replicate, producing flashes, shadows, and reflections that emphasise depth and internal movement. The adamantine lustre appears spontaneously across the raw faces, reinforcing the noble identity of diamond even in its most primal state. There is a striking contrast between the rugged reality of its extraction and the refined nobility of the material itself. Lifted from alluvial gravels and preserved in its original form, this diamond carries both the brutality of its geological journey and the quiet elegance of rare natural colour. It is a specimen that communicates authenticity, origin, and rarity without needing human intervention.

This specimen offers collectors a direct connection to one of Africa’s most respected diamond regions, combining colour stability, geological authenticity, and historical provenance. Its balance of colour, texture, and origin makes it an ideal piece for advanced collections focused on natural coloured diamonds, African sources, or untouched crystal specimens. Legendary Potential: The strength and consistency of this fancy greenish blue colour give the diamond enduring appeal well beyond its size. Preserved as a natural crystal, it stands as a geological artefact of rarity and authenticity. Studied for lapidary purposes, its colour behaviour suggests strong retention potential even in a very small finished stone. Whether kept untouched or used as a reference for future cutting decisions, this diamond embodies the timeless dialogue between raw nature and noble material, securing its place as a piece of lasting significance. ——————- 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.

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
