Its form is not governed by symmetry, but by movement, a coalesced formation where growth phases met, merged and solidified into a sculptural, irregular mass that feels both powerful and deliberate. The morphology reveals a distinctly coalesced growth structure, composed of a dominant primary body with a lateral extension that suggests multiple nucleation points fusing during formation. The silhouette is asymmetrical yet balanced, with a stable base and a subtly rising profile that culminates in a gently elevated ridge. Rather than presenting flat geometric planes, the surface is alive with tightly packed micro-relief textures and natural crystalline undulations. These micro-structures interlock across the body, forming a cohesive yet complex external architecture. Its colour is classified as Vivid Bright Yellow, and the saturation is immediate and commanding. The yellow is intense, clean and luminous, free from muddiness or brownish influence. Under neutral lighting, the stone maintains a strong, stable chromatic presence. When exposed to direct illumination, the internal body responds with heightened brilliance, amplifying the yellow core and creating a vivid internal radiance that seems to glow from within. The translucency allows light to penetrate and scatter through internal growth zones, producing depth rather than opacity. This internal interaction enhances the vivid classification, giving the stone a layered visual character that shifts subtly as it is rotated. Across the surface, the adamantine lustre expresses itself through concentrated flashes on natural micro-planes. Reflections gather along raised nodular zones and textured ridges, creating sharp scintillation without the need for polishing. The result is a lively optical performance that complements the sculptural form rather than overpowering it. Recovered from the alluvial deposits of Lunda Norte, Angola, this diamond carries the geological authenticity of ancient river systems that naturally preserved stones of strong colour integrity. Its coalesced formation remains fully intact, untreated and unmodified, preserving both its vivid chromatic identity and its rare morphological expression. This specimen does not rely on conventional symmetry to communicate value. Its rarity is expressed through vivid saturation, sculptural coalesced architecture and uncompromised natural formation, a compelling convergence of colour and structure in raw form. Specifications: • Weight: 0.05 g • Weight in carats: 0.25 ct • Dimensions: 3.5 × 2.5 × 2.5 mm • Origin: Lunda Norte, Angola • Gem material: Natural diamond • Crystal form: Natural rough diamond with coalesced formation • Morphology: Irregular coalesced growth with lateral extension • Colour: Vivid Bright Yellow • Colour distribution: Even and saturated throughout the body • Transparency: Translucent • Lustre: Adamantine • Surface features: Dense natural micro relief growth texture • Condition: Natural, unpolished, untreated Notable Points: • Distinct coalesced formation with asymmetrical sculptural silhouette • Strong Vivid Bright Yellow saturation with clean chromatic purity • Even colour distribution without visible zoning or dilution • Lateral growth extension indicating multi-phase crystal development • Dense natural micro texture enhancing light interaction • Pronounced adamantine flashes across natural micro-planes • Translucent body allowing internal depth perception • Stable and luminous behaviour under direct illumination • Authentic Angolan alluvial provenance • Untreated and fully preserved natural rough morphology • Compact size with high visual intensity • Rare structural character combined with vivid colour classification Collector’s Interest: Vivid Bright Yellow diamonds already occupy a highly desirable position within natural colour categories. When paired with a preserved coalesced formation, the collecting appeal deepens further. This specimen offers not only chromatic strength but also morphological individuality, making it particularly attractive to collectors who value natural growth complexity alongside vivid saturation. Its Angolan origin reinforces its geological significance and long-term credibility within advanced coloured diamond collections. Lapidary Potential: The intensity and stability of the vivid yellow colour suggest strong retention potential should cutting ever be considered. However, the coalesced formation and preserved surface architecture provide intrinsic specimen value that would be permanently altered by intervention. In its current state, the diamond offers both visual impact and morphological integrity, standing as a fully natural representation of vivid coloured diamond growth ——————- 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
