Description:
This natural vivid yellow diamond displays an exceptionally preserved cubic crystal morphology, with remarkably balanced geometry and sharply defined structural proportions across nearly the entire specimen. The crystal retains an almost flawless cubic habit, interrupted only by a subtle natural variation along one vertex, a detail that reinforces its authenticity while preserving the overwhelming visual integrity of the formation.

Its architectural presence is immediately striking. Unlike heavily distorted or fragmented rough diamonds commonly encountered in alluvial deposits, this specimen maintains strong cubic symmetry with highly recognisable crystal definition from virtually every angle. The result is a crystal that feels structured, stable and visually commanding despite its compact dimensions.

Colour is dominated by vivid yellow saturation with rich golden undertones distributed naturally throughout the crystal body. Under ambient lighting, the diamond presents a warm and concentrated yellow appearance with notable chromatic depth. When illuminated from behind or exposed to stronger transmitted light, the internal colour becomes dramatically more intense, transforming into a highly luminous vivid yellow glow that amplifies the specimen’s visual energy and optical presence.

One of the most compelling characteristics of this diamond is its extraordinary surface texture. The cubic faces are not flat or sterile, but organically sculpted with dense natural relief and highly articulated crystalline growth structures. Countless micro textured formations, elevated ridges and reflective growth patterns create a rugged yet sophisticated surface landscape that continuously interacts with light.

This pronounced relief gives the specimen exceptional dimensionality. Reflections move dynamically across the textured faces, producing fragmented adamantine flashes and concentrated highlights that shift with every change in viewing angle. Rather than behaving like a polished gem, the crystal expresses light through its natural geological architecture, creating a far more organic and mineralogically authentic visual effect.

The lustre is particularly impressive for a rough diamond of this morphology. Sharp reflective zones emerge across the elevated surfaces, contrasting beautifully with deeper textured recesses and reinforcing the perception of depth, structure and complexity throughout the specimen.

Recovered from the diamond rich alluvial deposits of Lunda Norte, Angola, this crystal remains entirely natural, untreated and unpolished, preserving both its exceptional cubic morphology and its vivid yellow colouration exactly as formed in nature.

This is not simply a coloured rough diamond. It is a highly preserved cubic crystal combining near flawless geometry, vivid optical behaviour and extraordinary organic surface relief within a rare and visually powerful natural specimen.

Collector’s Interest:
Natural cubic diamonds displaying near complete geometric preservation are considerably less common than fragmented or irregular rough crystals typically encountered in the market. When combined with vivid yellow saturation and strongly developed natural surface relief, specimens such as this become particularly desirable among collectors focused on morphology and crystallographic aesthetics.

This diamond stands out through the unusual coexistence of precision and organic complexity. The crystal maintains highly recognisable cubic symmetry while simultaneously exhibiting deeply textured natural surfaces filled with elevated growth structures and reflective relief.

Its optical behaviour under backlighting further enhances its collector appeal, transforming the specimen into an intensely luminous vivid yellow crystal with remarkable visual energy.

For collectors, this is not merely a rough diamond, but a highly expressive mineralogical object where colour, geometry and texture coexist in unusually harmonious balance.

Lapidary Potential:
Although cutting could theoretically be considered, doing so would permanently remove the defining cubic morphology, the organic crystalline relief and the natural surface architecture responsible for the specimen’s identity and collector significance.

The diamond achieves its highest value in preserved natural form, where its vivid optical behaviour, near flawless cubic geometry and extraordinary textured surfaces can be fully appreciated without alteration.

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.
