DESCRIPTION: Like a tiny sphere of green spring light captured before it could escape, this remarkable natural diamond presents a vivid green appearance that feels fresh, energetic and intensely alive. Across its rounded body, the colour shifts naturally between bright green and lighter lime expressions, creating a lively chromatic surface that becomes even more dramatic under illumination. When light is introduced from behind, the diamond undergoes a striking transformation. The green intensifies dramatically toward a brilliant neon lime appearance, giving the impression of colour being illuminated from within rather than simply reflected from the surface. This strong optical response is one of the most visually compelling characteristics of the specimen. Its morphology is especially attractive. The diamond displays a naturally rounded shape approaching a near spherical form, creating excellent visual balance from multiple viewing angles. Rather than being defined by sharp cubic or octahedral geometry, its identity lies in this harmonious rounded architecture and the way the form concentrates colour within a compact three dimensional body. The surface preserves a dense natural microcrystalline texture composed of numerous minute reflective structures. These interact strongly with directional light, generating fragmented flashes of adamantine lustre across the exterior and producing a dynamic contrast between vivid colour, brightness and depth. Colour distribution is naturally varied, with areas of stronger green saturation accompanied by brighter lime zones. As the diamond is rotated, these differences become more apparent, creating continuous visual movement and making the specimen particularly responsive to controlled illumination and macro observation. According to the provenance information transmitted by the previous collector, the specimen originates from Lunda Norte, Angola. Preserved in its natural rough state, its rounded morphology, vivid green appearance, neon lime response and distinctive surface structure combine to create a highly individual coloured diamond specimen.

NOTABLE POINTS: • Vivid Green Colour Appearance The diamond presents an energetic natural green appearance with attractive lime tonal variation. • Striking Neon Lime Light Response Transmitted illumination dramatically intensifies the colour toward a brilliant neon lime expression. • Naturally Rounded Morphology Its near spherical architecture creates an unusually harmonious and immediately recognisable natural form. • Strong Three Dimensional Presence The rounded body allows colour and reflections to remain visually expressive from multiple orientations. • Dynamic Natural Colour Distribution Differences in saturation generate depth and continuous visual movement as the specimen is rotated. • Dense Microcrystalline Surface Texture Numerous minute natural structures create a complex and highly distinctive exterior. • Strong Adamantine Light Interaction Reflective surface structures generate lively flashes characteristic of natural diamond lustre. • Excellent Contrast Under Illumination Direct and transmitted light reveal markedly different expressions of the green colour. • Completely Natural Rough Form The original morphology and natural surface architecture remain preserved without cutting or polishing. • Distinctive Collector Character Rounded geometry, vivid colour appearance and dramatic light response combine into a highly individual specimen. COLLECTOR’S INTEREST: Natural rough diamonds displaying an immediately recognisable colour appearance and distinctive morphology hold particular appeal because they preserve characteristics that would normally disappear during cutting. In this specimen, the naturally rounded form works beautifully with the vivid green appearance, creating a compact crystal whose identity is unmistakable even before illumination is introduced. Its transformation under transmitted light adds another dimension, as the already vivid green intensifies toward a brilliant neon lime expression. Together with the natural microcrystalline surface and adamantine reflections, this optical behaviour gives the specimen excellent display character and strong individuality within a collection of natural coloured diamonds. LAPIDARY POTENTIAL: This natural rough diamond may offer potential for jewellery design, polishing, faceting or preservation in its original form. However, as the origin, distribution and stability of the colour have not been laboratory determined, colour retention during cutting, polishing or any other lapidary procedure cannot be guaranteed. Any lapidary work should be assessed and carried out by a qualified professional, taking into consideration the internal structure, inclusions and colour distribution of the specimen. ——————- 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
