Its colour recalls the sharp brilliance of midday sunlight striking a reflective surface, direct, radiant and uncompromising, rather than warm or diffuse. This is a yellow that does not fade into gold or lemon tones, but instead maintains a luminous intensity that dominates the crystal from every angle, giving the impression that light itself has been structurally embedded within the diamond. The crystal exhibits a natural cubic morphology, with balanced proportions that give the stone a grounded, architectural presence despite its very small size. Each face shows natural growth textures and fine surface relief, preserving the raw signature of its formation environment. These subtly uneven surfaces interact dynamically with light, producing flashes that travel across the crystal rather than remaining static, reinforcing the radiant character of the colour. Under illumination, the diamond reveals a vivid internal glow, shifting between electric yellow and bright solar tones depending on angle and light intensity. The colour appears evenly distributed throughout the crystal body, without zoning or dilution, which is particularly notable given the specimen’s size. This chromatic consistency allows the diamond to project a strong visual presence that far exceeds its physical dimensions. Recovered from the alluvial deposits of Lunda Norte, Angola, this diamond carries the geological imprint of ancient river systems that naturally preserved crystals with exceptional colour stability. Transported and concentrated over vast geological timescales, the crystal retained both its cubic habit and its radiant yellow saturation in an entirely natural, untreated state. Rather than relying on scale or polish, this specimen communicates rarity through purity of colour, structural balance and geological honesty. It stands as a precise example of how intense colour and disciplined crystal form can coexist in natural coloured diamonds, offering a focused and highly expressive mineral statement. Specifications: • Weight: 0.03 g • Weight in carats: 0.15 ct • Dimensions: 2 × 2 × 2 mm • Origin: Lunda Norte, Angola • Gem material: Natural diamond • Crystal form: Natural rough cubic crystal • Colour: Fancy vivid radiant yellow • Colour distribution: Even and highly concentrated • Transparency: Translucent • Lustre: Adamantine • Surface features: Natural growth textures and crystalline relief • Condition: Natural, unpolished, untreated Notable Points: • Distinct natural cubic crystal morphology • Radiant yellow colour with strong solar character • High colour saturation maintained across all crystal faces • Natural surface textures clearly preserved • Strong light interaction producing dynamic flashes • Compact dimensions with disproportionate visual impact • Untreated and fully natural specimen • Stable colour preserved through alluvial transport • Clear balance between geometric form and organic growth features • Colour character reminiscent of concentrated solar light rather than metallic tones • Rare pairing of vivid colour intensity and cubic habit • Excellent reference example for natural coloured diamond morphology Collector’s Interest: For collectors of natural coloured diamonds, this specimen offers a highly focused expression of colour taxonomy and crystal habit. Radiant yellow diamonds with true cubic morphology are uncommon, particularly when colour saturation remains vivid and evenly distributed at such small scale. Its Angolan provenance further reinforces its geological credibility, making it especially appealing for advanced collections centred on natural colour, crystal form diversity and untreated specimens. This diamond rewards close inspection and comparison, serving as a precise study piece rather than a decorative object. Lapidary Potential: Although the vivid colour may suggest cutting possibilities, the true value of this diamond lies in its preserved natural structure. Any cutting would inevitably sacrifice the rare cubic habit and natural surface features that define its identity. As such, this specimen is best conserved in its original state, where its colour behaviour, crystal symmetry and growth textures can be fully appreciated as a natural geological record rather than a transformed gemstone. ——————- 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
