DESCRIPTION: Like a frozen pearl emerging from a crystalline shell, this exceptional natural rough diamond immediately distinguishes itself through a remarkable rounded protuberance rising prominently from the central area of the crystal. This unusual three dimensional feature breaks the otherwise compact morphology and gives the specimen an unmistakable sculptural identity from its most expressive viewing angle. The main body presents a rounded freeform structure with naturally softened contours, while the central protruding formation creates a second visual level above the surrounding surface. Rather than appearing flat or uniform, the diamond develops a complex architecture of recesses, raised areas and natural crystalline relief that changes significantly as the specimen is rotated. Its colour is distinctly white, with a clean neutral appearance and subtle variations in translucency across the crystal. This purity of tone allows the morphology itself to become the dominant visual element, while brighter areas catch the light with sharp flashes characteristic of diamond’s adamantine lustre. The surface is richly textured with natural micro crystalline relief, growth structures and numerous minute reflective planes. Around the central protuberance in particular, the interaction between raised and recessed areas creates an intricate landscape of light and shadow, producing a highly dynamic appearance under directed illumination. Under backlighting, the outer portions of the crystal become increasingly luminous, revealing additional depth within the body while preserving the more solid visual presence of the central rounded feature. Reflection, diffusion and translucency combine to create a specimen whose appearance changes noticeably depending on the direction of light. Originating from the Marange Diamond Fields, Manicaland Province, Zimbabwe, this completely natural, unpolished and untreated diamond combines a clean white colour, strong adamantine reflections, preserved surface architecture and an unusual central rounded protuberance. The result is a highly individual rough diamond whose morphology becomes as important as its optical character. SPECIFICATIONS: • Weight: 0.15 g • Weight in carats: 0.75 ct • Dimensions: 6 × 5 × 5 mm • Origin: Marange Diamond Fields, Manicaland Province, Zimbabwe • Gem material: Natural Diamond • Crystal system: Cubic • Crystal form: Natural rough crystal • Morphology: Rounded freeform crystal with prominent central protuberance • Defining morphological feature: Rounded protruding formation emerging from the central area • Colour: White • Colour distribution: Predominantly even with subtle natural tonal variation • Transparency: Translucent • Lustre: Adamantine • Surface features: Natural growth textures, micro crystalline relief, recessed areas and multiple reflective micro planes • Treatment: None • Condition: Natural, unpolished and untreated NOTABLE POINTS: • Distinctive Central Protuberance A prominent rounded formation rises naturally from the central area, giving the specimen an immediately recognisable three dimensional character. • Unusual Sculptural Morphology Raised and recessed areas create a complex natural architecture rather than a simple uniform rough form. • Clean White Colouration The diamond displays a neutral white appearance that allows its morphology and surface reflections to dominate visually. • Strong Adamantine Lustre Natural crystalline planes produce crisp and bright flashes across multiple areas of the specimen. • Complex Surface Relief Fine growth textures and micro crystalline structures create a highly detailed natural surface. • Dynamic Light Interaction Changes in viewing angle continually reveal new reflective points, shadows and morphological details. • Enhanced Under Backlighting Transmitted light increases luminosity in the outer portions of the crystal and reveals additional internal depth. • Strong Three Dimensional Presence The protruding central feature gives the diamond significant visual volume despite its compact overall proportions. • Preserved Natural Architecture No cutting or polishing has removed the original growth features or altered the natural form. • Natural Translucency Partial light penetration creates a balance between internal luminosity and solid crystalline presence. • Completely Untreated The diamond remains in its original natural rough state with no polishing, cutting or enhancement. • Marange Provenance Originates from the Marange Diamond Fields in Manicaland Province, Zimbabwe. COLLECTOR’S INTEREST: For collectors of natural rough diamonds, morphology can be every bit as compelling as colour or transparency. In this specimen, the rounded central protuberance immediately becomes the defining feature, creating a highly individual silhouette and a natural three dimensional architecture that changes substantially with rotation. The clean white body colour, strong reflective behaviour and richly textured surface further enhance that morphology. Rather than presenting as a conventional rounded rough diamond, this crystal possesses a pronounced sculptural quality that gives it a distinctive identity within a collection of natural uncut diamonds. Its Marange provenance, preserved surface character and complete lack of polishing or treatment strengthen its appeal as a mineralogical specimen in which the original natural form remains fully intact. LAPIDARY POTENTIAL: Although the material could technically be considered for cutting, any intervention would permanently remove the rounded central protuberance and much of the natural surface architecture that gives this specimen its individuality. Its strongest value lies in preservation as a complete natural rough diamond, allowing its unusual morphology, white colour, adamantine lustre and preserved crystalline textures to remain fully visible. ——————- 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
