Vivid Iceberg Blue Diamond • 无底价 • 稀有且独特的光泽 - 高度: 6 mm - 宽度: 5 mm- 0.17 g - (1)

DESCRIPTION:
Like a fragment of ancient glacier light captured in crystalline form, this remarkable natural rough diamond displays an icy blue appearance of striking freshness and delicacy. Its visual character immediately evokes compact glacial ice illuminated from within, combining a pale yet expressive blue body tone with a softly luminous presence that gives the specimen an unmistakably cool and elegant identity.

The colour appearance is not flat or monotonous. Instead, it shifts subtly between very light glacial blue, pale frozen aqua and slightly brighter icy zones depending on illumination and viewing angle. This gentle variation creates a refined internal liveliness and allows the specimen to retain visual depth despite its compact dimensions.

Its morphology is highly distinctive. Rather than presenting a rounded crystal habit, the specimen develops as a low, irregular rough form with a horizontally spread profile and a strongly textured upper surface. The outline appears organic and naturally sculptural, with uneven relief, compact elevations and multiple angular micro features that give the crystal a rugged yet harmonious appearance from every angle.

The surface structure is especially attractive under light. Dense natural crystalline textures and numerous small reflective planes scatter illumination across the specimen, producing fragmented adamantine flashes over the rough exterior. These reflections are not polished or artificial, but arise directly from the preserved natural surface, reinforcing the authenticity and mineralogical character of the piece.

Transparency is translucent overall, with some areas appearing slightly more open and luminous than others. Under stronger illumination, the specimen brightens noticeably and the icy blue appearance becomes more vivid and radiant, giving the impression of light diffusing through frozen crystalline matter. This optical behaviour contributes strongly to the specimen’s visual appeal.

According to the provenance information transmitted by the previous collector, the diamond originates from Lunda Norte, Angola. It is presented in its natural rough state and has not been accompanied by laboratory documentation. As such, the origin, distribution and stability of the colour appearance have not been scientifically determined.

This is a specimen whose appeal lies in atmosphere as much as structure. With its cool glacial appearance, compact sculptural morphology and lively natural surface reflections, it offers a highly individual expression of rough diamond in an elegant and visually memorable form.

NOTABLE POINTS:
• Distinctive icy blue appearance
Displays a refined pale blue visual character with strong freshness and elegance.

• Glacial visual identity
The specimen evokes the look of compact illuminated ice, giving it an immediately recognisable personality.

• Naturally varied colour expression
Subtle tonal variation creates depth and prevents the appearance from feeling flat.

Its low, horizontally spread rough form gives the specimen a very individual natural silhouette.

• Rugged sculptural surface
The crystal preserves a richly textured exterior with uneven relief and compact elevations.

• Dense natural crystalline texture
Numerous small surface structures enhance light interaction and visual complexity.

• Fragmented adamantine reflections
The rough exterior produces lively reflective flashes across the specimen.

• Authentic untreated rough state
Presented in its natural uncut and unpolished form.

• Strong three dimensional character
Despite its compact size, the specimen shows excellent visual presence through structure and surface relief.

Lunda Norte, Angola, according to the provenance information transmitted by the previous collector.

• Excellent display specimen
Highly attractive under controlled lighting and especially suitable for macro photography.

COLLECTOR’S INTEREST:
Rough diamonds displaying an icy blue appearance possess a particularly distinctive collector appeal, especially when the colour is combined with an unusual natural morphology and expressive surface character. In this specimen, the cool glacial visual identity works beautifully with the flattened sculptural form and the lively network of natural reflective textures.

Its visual strength does not rely on size or conventional faceting, but on atmosphere, natural structure and the way light activates the preserved rough crystal surface. The specimen is not accompanied by laboratory documentation, and the origin, nature and stability of the colour have therefore not been scientifically determined.

For collectors, it offers a highly individual combination of elegant pale blue appearance, natural rough authenticity 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.

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.
