トリゴンを持つ希少で鮮やかな金色のダイヤモンド • 最低落札価格なし • 稀少な色と表面の組成 - Height: 3.5 mm - Width: 3.5 mm- 0.07 g - (1)

DESCRIPTION:
Like a fragment of condensed sunlight, this natural golden diamond captures the eye immediately through the warmth of its colour and the extraordinary geometric language written across its surface. Most remarkable of all is one of its principal faces, which is densely covered from edge to edge with natural trigons, creating the impression that the crystal has been intricately engraved by nature itself. Combined with its rare cubic morphology, this exceptional trigon coverage gives the specimen an immediate collector identity and elevates it well beyond the appeal of a conventional rough diamond.

The crystal presents a compact and strongly preserved cubic habit, a morphology that is both visually striking and increasingly appreciated among collectors of natural rough diamonds. Rather than appearing rounded or irregular, the specimen retains a distinctly architectural form, with balanced proportions, flat principal faces and a solid three dimensional presence. Its compact geometry gives the diamond a powerful and disciplined visual character, while the natural relief across the faces prevents the specimen from ever appearing static or ordinary.

Its colour is best described simply as golden. Under normal viewing conditions, the diamond displays a rich and concentrated golden body colour with a warm, slightly honeyed expression. When stronger light is introduced, the colour becomes far more vivid and luminous, transforming into a brighter and more energetic golden tone. This light response gives the crystal a strong optical vitality and reinforces the intensity of its natural colour without requiring any treatment or enhancement.

The trigon covered face is one of the defining features of the piece. Trigons are minute triangular natural features that form on diamond surfaces through growth and dissolution processes, and they are highly valued because they record the crystal’s natural geological history directly on the exterior. In many diamonds, trigons appear only sporadically or in isolated areas. In this specimen, however, they occur in unusually dense concentration, spread across the face almost continuously from one side to the other. This exceptional abundance is far more visually compelling and considerably less common than the presence of only one or two isolated trigons, making the crystal particularly desirable for collectors who value crystallographic detail and natural surface phenomena.

The surface as a whole remains fully natural and unpolished, preserving the diamond’s authentic mineralogical identity. Across the crystal, the interplay between the golden colour, the cubic architecture and the dense trigon microrelief creates a highly expressive surface character. Light interacts dynamically with these natural formations, generating fragmented adamantine reflections and bright flashes that animate the specimen while preserving its raw geological authenticity.

Recovered from the Marange Diamond Fields, Chiadzwa, Manicaland, Zimbabwe, this diamond combines several features that rarely come together so effectively in such a compact crystal: vivid natural golden colour, strongly expressed cubic morphology and an exceptional face densely populated by trigons. The result is a natural diamond of strong visual presence, high crystallographic interest and unmistakable collector appeal.

NOTABLE POINTS:
• Rare natural cubic diamond morphology
The crystal preserves a compact and highly attractive cubic habit with strong structural definition.

• Exceptional dense trigon coverage
One principal face is densely covered with natural trigons from edge to edge, a highly distinctive and collector significant feature.

• Important crystallographic interest
The specimen offers direct visual evidence of natural diamond surface evolution through its exceptionally well developed trigon structures.

• Rich natural golden colour
The body colour displays a warm and concentrated golden tone with strong immediate visual appeal.

• Strong light response
Under stronger illumination, the colour becomes brighter and more vivid, enhancing the crystal’s optical presence.

• Fully natural surface preservation
The diamond remains unpolished and untreated, preserving its original geological character exactly as formed.

• Expressive adamantine lustre
Natural reflective planes produce lively flashes across the crystal without artificial enhancement.

• Strong architectural presence
Its cubic form gives the specimen a stable, balanced and visually powerful appearance.

• Surface microrelief of great visual interest
The combination of trigons and growth textures creates a highly engaging topography across the crystal.

• Uncommon collector combination
Golden colour, cubic habit and extensive trigon development rarely occur together so harmoniously in a single specimen.

• Highly photogenic natural crystal
The specimen responds especially well to directional lighting, revealing both colour intensity and surface detail.

• Desirable Zimbabwean provenance
Originating from the Marange Diamond Fields of Zimbabwe, a locality well known for natural rough diamonds of strong collector interest.

COLLECTOR’S INTEREST:
Natural rough diamonds become especially desirable when they preserve features that reveal not only beauty, but also crystallographic history. This specimen stands out precisely because it offers both. Its compact cubic morphology already gives it a rare and immediately recognisable identity, but the true distinction lies in the remarkable face densely covered with trigons.

For collectors, trigons are far more than decorative surface details. They are natural triangular microfeatures formed through geological processes and serve as direct evidence of the diamond’s evolutionary history. In this example, their abundance is particularly important. Rather than appearing as a few isolated triangular marks, they cover the surface in an unusually dense and visually impressive way, greatly increasing the mineralogical and aesthetic interest of the crystal.

When combined with the warm golden colour and the strong adamantine response to light, the result is a specimen that appeals on several levels at once: colour, morphology, rarity of surface structure and overall individuality. It is an unusually characterful natural diamond whose value resides as much in its preserved crystallographic authenticity as in its visual beauty.

LAPIDARY POTENTIAL:
Although cutting could theoretically be considered, any faceting would permanently remove the rare cubic morphology and, most importantly, the extraordinary trigon covered face that gives this diamond much of its identity and collector value.

In its present state, the crystal preserves its complete natural crystallographic character, original surface microtopography and vivid golden colour exactly as formed in nature. Its strongest value resides in preservation as a natural collector specimen, where its morphology, surface phenomena and geological authenticity can be fully appreciated without alteration

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:
