Description: Like a fragment of an untouched tropical lagoon preserved in crystalline form, this natural fancy Caribbean Blue diamond displays a colour of remarkable purity and intensity. The Caribbean Blue is richly saturated, luminous, and visually intense, recalling the crystal clear waters of an unspoilt Caribbean lagoon where sunlight penetrates exceptional depth, revealing an almost electric Caribbean Blue tone untouched by green or secondary hues. It is a colour that feels both geological and aquatic, evoking the serene depth and vibrant brilliance of pristine tropical waters. Recovered from the alluvial deposits of Lunda Norte, Angola, this diamond carries the legacy of one of the most important diamond producing regions in Africa. Transported and shaped by ancient river systems, alluvial diamonds from this area are known for preserving natural colour expression and structural authenticity. Their geological journey often results in stones whose chromatic behaviour remains remarkably expressive while fully preserving their natural crystal character. The crystal remains entirely natural, presenting a compact rough morphology with softly rounded contours and irregular crystallographic surfaces formed solely by geological forces. Its exterior is covered by an intricate network of natural crystalline relief and growth textures, creating countless microscopic reflective planes that interact dynamically with light from every viewing angle. Rather than producing the uniform brilliance associated with polished diamonds, these untouched crystal faces generate a complex interplay of reflections that continuously enriches the apparent depth and saturation of the Caribbean Blue colour. The densely textured surface gives the specimen an almost velvety crystalline appearance while preserving the unmistakable character of a completely natural diamond. Every ridge, depression and growth feature contributes to a remarkably tactile visual texture, allowing the stone to reveal different nuances of Caribbean Blue as illumination changes across its natural relief. Even without any cutting or treatment, the adamantine lustre remains immediately recognisable, emerging naturally between the countless preserved crystal faces. This piece stands as a quiet yet powerful expression of colour and geological authenticity. Untreated and entirely unaltered, it communicates its value through the remarkable purity of its Caribbean Blue colour, its richly preserved natural surface, and the extraordinary geological history recorded within every crystallographic feature. It is a diamond where colour speaks first, shaped not by human design, but by immense pressure, geological time, and the natural language of the Earth itself.

This specimen offers collectors an exceptional example of Angolan alluvial diamond heritage, combining vivid colour, untouched crystal morphology, and remarkable surface preservation. Its densely textured crystalline relief enhances both its visual character and mineralogical authenticity, while its distinctive Caribbean Blue tonality gives the stone an immediate and memorable presence. Collectors who appreciate natural coloured diamonds in their original geological state will recognise this specimen as an outstanding expression of both colour and natural crystal preservation. Lapidary Potential: The remarkable saturation of its Caribbean Blue colour suggests excellent colour retention potential if carefully cut. Equally important, the preserved natural morphology provides valuable insight into the crystal’s original growth orientation and crystallographic development. Whether maintained as a natural mineral specimen or considered for selective lapidary work, this diamond offers exceptional potential derived from the quality of its colour, its authentic crystal structure, and its outstanding geological preservation. ——————- 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
