強烈なヴァイオレット・ダイヤモンド • リザーブなし • 珍しい色と独特のフォルム - Height: 3 mm - Width: 3 mm- 0.04 g - (1)

Description:
Like a drop of violet light captured in crystalline form, this natural rough diamond displays a layered and expressive colour appearance. Its tones shift between pale lavender highlights, cool blue undertones and deeper violet areas, creating an engaging interplay of colour and reflection.

The visual character comes from the contrast between its violet appearance and the bright, silvery reflections across its surface. Depending on the lighting and viewing angle, some areas appear softer and more delicate, while others reveal a stronger concentration of colour.

The crystal presents a compact and naturally rounded morphology. Its outline is organic and irregular, with gently changing contours that give the specimen a distinctive presence from different angles.

The surface displays a dense granular texture and numerous small reflective planes. These catch the light individually, producing scattered flashes of adamantine lustre. Unlike the organised reflections of a faceted stone, the sparkle here follows the irregular contours of the rough crystal.

The visible colour distribution is uneven, with deeper violet and blue violet areas contrasting with lighter lavender tones. Bright reflections introduce pale, almost silvery accents, enhancing the perception of depth without creating a uniform colour appearance.

The specimen appears translucent in some areas and more opaque in others. This contrast contributes to its visual complexity, allowing lighter surface details to stand out against darker portions of the stone.

Its reflective lustre, textured surface and rounded form combine to create a strong three dimensional presence. The appeal lies in this relationship between colour, light and the character of the unpolished crystal.

Collector’s Interest:
This specimen offers collectors a combination of violet colour appearance, rounded morphology and a richly textured surface. Its interest lies in the way these features interact, with pale lavender and silvery reflections contrasting against deeper violet and blue undertones.

The unpolished form encourages observation from several angles. Changes in illumination reveal different reflective planes and alter the apparent balance between lighter and darker areas, giving the specimen a varied visual character.

For a collection focused on rough crystals, this piece offers interest through its appearance and surface structure. As no gemmological report accompanies it, the descriptive colour should not be interpreted as confirmation of natural colour origin, treatment status or a recognised colour grade.

Lapidary Potential:
This rough diamond may be considered for jewellery design, polishing, faceting or preservation in its existing form, subject to professional assessment. Its suitability for cutting and any potential finished yield have not been established.

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 proposed work should be assessed and carried out by a qualified professional, taking into consideration the internal structure, inclusions, surface characteristics 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.

Guarantee and resolution:
