Description: Like a concentrated pulse of vivid natural green, this remarkable diamond reveals a colour that is both energetic and intensely expressive. Its tone is not flat or uniform, but alive with variation, shifting between bright fresh green and lighter lime flashes that become significantly more intense under illumination. When light is introduced from behind, the diamond undergoes a striking transformation. The green brightens dramatically, evolving into a vivid neon lime tone that appears to glow from within the structure. This effect is driven by the internal composition of the stone, creating a visual impression of light being generated rather than simply reflected. The diamond presents a compact rounded freeform morphology, approaching a near spherical shape. Its proportions are well balanced, giving it a strong and harmonious presence despite its small size. The form is naturally refined, with smooth transitions across the surface that enhance its overall visual cohesion. The surface is composed of dense micro structured formations, creating a complex network of natural reflective planes. These features interact strongly with light, producing scattered flashes of adamantine lustre across the entire surface. The brilliance is fragmented and dynamic, resulting in a lively interplay between brightness and depth. Colour distribution is naturally irregular, with areas of stronger saturation contrasted by lighter zones. This variation enhances the perception of internal complexity and gives the diamond a sense of movement, particularly under changing lighting conditions. Transparency is limited, which contributes positively to the visual strength of the piece. Light is absorbed and re emitted across the surface rather than transmitted, intensifying the vivid green character and reinforcing its bold identity. The lustre is distinctly adamantine, expressed through multiple sharp reflections that give the surface a highly energetic appearance. Combined with its rounded morphology, this creates a compact yet visually powerful specimen. Recovered from the alluvial deposits of Lunda Norte, Angola, this diamond remains in its complete natural state. It has not been cut, polished or treated, preserving both its structure and its colour exactly as formed in nature. This is not simply a green diamond. It is a raw and concentrated expression of vivid natural green, elevated further by its remarkable neon response to light.

Collector’s Interest: Green diamonds represent one of the more unusual and desirable colour expressions within natural diamonds. In rough form, their colour appears more organic and dynamic, free from the constraints of faceting. This piece stands out through its vivid green intensity and its ability to transform under light into a neon lime expression. The rounded morphology enhances the way light interacts with the surface, while the micro structured texture adds depth and complexity. For collectors, this is a specimen defined by character. It offers a raw and authentic expression of natural colour, combined with strong visual impact and a highly engaging light response. Lapidary Potential: Although cutting could be considered, it would result in significant loss of material and would remove the natural surface features that define the identity of this diamond. In its current form, the piece is far more valuable as a natural specimen, preserving both its structural integrity and its unique colour behaviour. It is particularly well suited for display or for use in high end bespoke jewellery where its raw form and vivid green tone can be fully appreciated. ——————- 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
