This natural salt and pepper diamond embodies that expression, presenting a dense, irregular morphology where light is fragmented across a richly textured surface. The crystal displays a compact and uneven structure, with no dominant geometric faces, instead revealing a rugged, organic form shaped entirely by natural growth and geological processes. Its morphology is highly individual, with rounded protrusions and clustered micro surfaces that create a complex and visually engaging topology. Rather than transparency, the visual strength of this specimen lies in its surface behaviour. The exterior is composed of countless micro crystalline planes and granular textures that interact intensely with light. These natural features scatter illumination in multiple directions, producing sharp flashes of adamantine lustre across the surface. Under direct light, the diamond exhibits a vivid brilliance despite its included nature. The salt and pepper character is defined by the presence of internal inclusions and structural density, which prevent full transparency but enhance the stone’s visual depth and uniqueness. Light does not pass cleanly through the crystal, but instead activates a shimmering, almost metallic sparkle across its surface. Certain areas reveal slightly smoother zones where the lustre becomes more concentrated, creating contrast between reflective micro planes and more granular sections. This interplay gives the specimen a dynamic optical behaviour, shifting continuously as the viewing angle changes. The overall appearance is one of raw natural power. This is not a refined or faceted diamond, but a geological fragment preserved in its original state, where inclusions, irregular growth and surface complexity define its identity. Recovered from alluvial deposits, the specimen remains completely natural, untreated and unpolished. Its irregular morphology, strong adamantine response and distinctive salt and pepper character combine to create a unique and highly individual diamond specimen. This is a piece where texture becomes brilliance, and imperfection becomes identity.

Unlike traditional gem grade diamonds, these specimens emphasise individuality, texture and geological authenticity rather than clarity. This example stands out through its strong surface activity and intense light interaction. The combination of adamantine flashes, granular structure and irregular morphology creates a visually engaging piece that changes continuously under different lighting conditions. Its relatively larger size for this category further enhances its presence, making it an attractive specimen for collectors interested in natural diamond forms that highlight inclusion driven aesthetics and unaltered geological history. Lapidary Potential: While the material could theoretically be processed, the high inclusion density and irregular morphology would limit traditional gem cutting potential. Any attempt to modify the stone would also eliminate the surface features that define its identity. In its current state, the diamond offers far greater value as a natural specimen, where its texture, lustre and raw structural complexity remain fully preserved. ——————- 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
