DESCRIPTION:
Like a concentrated pulse of vivid green captured in crystalline form, this remarkable natural rough diamond reveals a colour appearance 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 appearance brightens dramatically, evolving into a vivid neon lime tone that appears to glow from within the structure. This remarkable optical response creates 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. 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 in appearance, with areas of stronger visual 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 interacts predominantly with the dense internal structure and textured surface, intensifying the vivid green appearance and reinforcing its bold visual 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.

According to the provenance information transmitted by the previous collector, this diamond originates from Lunda Norte, Angola. It remains in its complete natural rough state, uncut and unpolished. The specimen is not accompanied by laboratory documentation, and the origin, distribution and stability of its green colour appearance have therefore not been scientifically determined.

This is a raw and concentrated expression of vivid green appearance, elevated further by its remarkable neon lime response to light and preserved natural diamond morphology.

NOTABLE POINTS:
• Intense vivid green appearance
Displays a highly expressive green appearance with strong visual saturation and natural tonal variation.
• Neon lime light response
Under backlighting, the observed green appearance intensifies dramatically towards a striking neon lime expression.
• Elegant rounded morphology
The near spherical freeform shape creates a strong and balanced visual presence.
• Strong micro structured surface
Dense natural formations enhance interaction with light across the entire specimen.
• Dynamic light scattering
Multiple reflective planes produce lively flashes across the rough surface.
• Expressive colour variation
Differences in apparent saturation create depth and internal visual movement.
• Adamantine lustre expression
Maintains the characteristic lustre of diamond through numerous fragmented reflections.
• Compact and visually powerful form
The combination of colour appearance, morphology and surface structure produces considerable visual impact.
• Natural rough state
Presented uncut and unpolished, preserving its original morphology and surface character.
• Distinct from traditional faceted diamonds
Its appeal is driven by colour appearance, raw structure and preserved natural surfaces rather than conventional faceted brilliance.
• High visual impact
The vivid green appearance immediately dominates perception, particularly under controlled illumination.
• Angolan provenance
Lunda Norte, Angola, according to the provenance information transmitted by the previous collector.
• Unusual green appearance
The vivid green and lime visual character gives the specimen a particularly distinctive identity.
• Strong three dimensional presence
Its rounded natural morphology enhances display and perception from multiple orientations.
• Excellent display specimen
Highly responsive to controlled lighting and macro photography.

COLLECTOR’S INTEREST:
Rough diamonds displaying green coloration occupy a particularly fascinating position within natural diamond collecting. In specimens such as this, the colour appearance interacts directly with the original crystal surface and internal structure, producing an organic visual character fundamentally different from that of a polished gemstone.

This piece stands out through its vivid green appearance, pronounced lime response under illumination and beautifully rounded natural morphology. The dense micro structured surface creates numerous reflective points, while the compact near spherical form gives the specimen a cohesive and immediately recognisable presence.

The specimen is not accompanied by laboratory documentation, and the origin, nature and stability of its green colour appearance have therefore not been scientifically determined. For collectors, its interest resides in the combination of natural rough diamond identity, distinctive visual coloration, expressive light behaviour and provenance attributed to Lunda Norte, Angola.

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,
