ファンシーイエロー・クラスターダイヤモンド • リザーブ価格なし • 世界に一つだけのジオメトリ - Height: 4 mm - Width: 3.5 mm- 0.08 g - (1)

DESCRIPTION:
Like a cluster of golden domes fused into a single natural sculpture, the defining feature of this extraordinary natural yellow diamond is its remarkable rounded intergrown architecture. Rather than presenting one dominant geometric crystal, the specimen is composed of numerous rounded and lobed growth units that developed together and became crystallographically united into one compact natural aggregate.

From every angle, a different arrangement of these rounded forms becomes visible. Some units rise prominently from the surface, while others merge partially into neighbouring growths, creating a complex three dimensional structure with no single dominant face. The result is an unusually sculptural diamond morphology in which repetition, curvature and intergrowth become the principal visual language of the specimen.

Its colour is a rich natural yellow, distributed throughout the aggregate with a warm luminous appearance under ordinary illumination. When stronger light passes through the crystal, the yellow becomes considerably brighter and more vivid, intensifying the visual separation between the individual growth units and revealing greater depth within the structure.

The surface is particularly fascinating. Fine natural growth relief covers much of the specimen, forming dense stepped, striated and finely textured patterns across the rounded units. These microscopic variations catch the light from countless directions, producing a sparkling surface character while preserving the natural morphology of the diamond.

What makes the specimen especially compelling is the contrast between its compact overall form and the complexity of its surface architecture. The individual rounded growth units remain clearly distinguishable, yet together they form one coherent natural crystal aggregate, giving the piece an almost organic appearance rarely associated with the strict geometric image normally attributed to diamond.

Originating from the Marange Diamond Fields, Manicaland Province, Zimbabwe, this untreated rough diamond combines rich natural yellow colour, an unusual rounded intergrown morphology and beautifully preserved growth textures. It is a distinctive example of how diamond crystallisation and subsequent natural surface development can produce forms that are simultaneously mineralogical, sculptural and highly individual.

NOTABLE POINTS:
• Exceptional Rounded Intergrowth
Numerous rounded growth units developed together and became naturally fused into a single compact diamond aggregate.

• Highly Sculptural Morphology
The specimen has an almost organic three dimensional appearance created entirely by natural crystal growth.

• Complex Multi Unit Architecture
Each viewing angle reveals a different relationship between the individual rounded and lobed formations.

• Rich Natural Yellow Colour
The entire specimen displays a strong warm yellow body colour with excellent visual presence.

• Bright Response Under Transmitted Light
Backlighting intensifies the yellow and increases the perception of depth between the different growth units.

• Dense Natural Growth Relief
Fine stepped and striated textures cover much of the surface and document the crystal’s natural development.

• Strong Adamantine Reflections
Numerous minute surface planes interact with the light, generating bright flashes across the aggregate.

• Organic Versus Crystalline Contrast
Its rounded external appearance contrasts beautifully with the microscopic order preserved within the growth textures.

• Completely Natural Rough State
Its colour, morphology and surface architecture remain untouched by cutting or polishing.

• Marange Provenance
The specimen originates from the Marange Diamond Fields of Manicaland Province, Zimbabwe.

COLLECTOR’S INTEREST:
Natural diamond aggregates with such an unmistakably rounded and multi unit morphology offer a very different visual experience from conventional single crystals. Here, the repeated lobed formations create a natural sculptural structure in which no two viewing angles appear exactly alike.

Its rich yellow colour, compact three dimensional form and exceptionally detailed surface relief give the specimen a strong individual identity. For a collector interested in unusual rough diamond morphology, the natural intergrowth itself is the principal attraction and deserves to remain fully preserved.

LAPIDARY POTENTIAL:
Although the material could theoretically be considered for cutting, doing so would permanently destroy the rounded intergrown architecture that defines the specimen. Its strongest value lies in preservation as a complete natural crystal aggregate, where its colour, complex morphology and exceptional growth textures can all be 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.

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.
