宏伟的黑欧泊宝石 • 3.15 克拉 • 令人难以置信的全光谱色彩展现 - 高度: 12 mm - 宽度: 9 mm- 0.63 g - (1)

DESCRIPTION:
This exceptional Ethiopian Black Opal presents a complete full spectrum play of colour, with vivid red, orange, yellow, green, blue, violet and pink appearing throughout its dark translucent body. Rather than depending on one dominant chromatic area, the gemstone reveals colour across multiple internal levels, producing a continuously changing optical display as the stone is rotated or the direction of illumination changes.

The warm colours are particularly remarkable. Intense crimson red, molten orange and brilliant yellow emerge in concentrated flashes, immediately attracting the eye and providing the visual strength most highly valued in precious opal. These warmer tones are complemented by vivid electric green, deep blue, purple and magenta, creating an unusually complete and balanced spectral range.

Its internal colour architecture is highly dynamic and varied. Some areas display broad rolling fields of red, violet and green, while others reveal smaller fragments, streaks and concentrated flashes that appear to move beneath the polished surface. Different orientations expose entirely different chromatic compositions, allowing each side of the gemstone to present its own distinctive arrangement of colour.

The dark body tone provides exceptional contrast, intensifying the brightness and saturation of every visible hue. The colours appear suspended at different depths within the opal rather than restricted to a single surface plane, creating a powerful sense of dimension and internal movement. Under direct illumination, the stone becomes especially vivid, revealing strong colour activation across nearly the entire visible spectrum.

The gemstone has been polished into a beautifully rounded oval cabochon with generous curvature and excellent surface lustre. This shape allows light to enter from multiple angles while preserving substantial depth, enhancing both the rolling colour behaviour and the perception of colour emerging from within the body of the stone.

Originating from Welo in the Oromia Region of Ethiopia, this opal combines a highly desirable dark body tone with extraordinary spectral diversity, vivid red presence and strong multidirectional colour activation. Its complete play of colour, rounded form and dramatic optical character create an outstanding collector gemstone with exceptional visual presence.

NOTABLE POINTS:
• Complete full spectrum play of colour
Displays red, orange, yellow, green, blue, violet and pink throughout the gemstone.
• Exceptional presence of vivid red
Strong crimson and scarlet flashes appear across several internal zones.
• Highly desirable dark body tone
The dark translucent base creates powerful contrast and enhances every spectral colour.
• Intense multidirectional colour activation
Different viewing angles reveal entirely new chromatic arrangements.
• Strong warm colour expression
Molten orange, golden yellow and vivid red form some of the most visually dominant areas.
• Rich cooler spectral colours
Electric green, blue, violet and magenta complete the gemstone’s extensive colour range.
• Impressive internal depth
Colour appears to originate from multiple layers within the opal rather than from a single plane.
• Dynamic rolling colour behaviour
Movement causes the spectral flashes to travel and transform throughout the stone.
• Beautiful rounded oval cabochon
The generous curvature enhances light entry and creates a strong three dimensional presentation.
• Outstanding collector quality optical performance
The combination of dark body tone, red presence and complete spectral diversity creates exceptional visual impact.

COLLECTOR’S INTEREST:
Black Opals displaying a complete visible spectrum are especially desirable, particularly when vivid red appears alongside strong green, blue and violet. This specimen offers that combination within a dark translucent body that significantly intensifies the colour contrast.

Its appearance changes dramatically with movement, allowing every orientation to reveal a different internal composition. For collectors of Ethiopian opal and gemstones defined by exceptional optical behaviour, this is a highly expressive and visually memorable specimen.

LAPIDARY POTENTIAL:
The gemstone has already been polished into a well proportioned oval cabochon that successfully exposes its complete play of colour. Its curvature and retained depth allow light to activate multiple internal layers while maintaining a strong and balanced form.

Further cutting would reduce both weight and colour depth. The present cabochon already provides an excellent balance between surface polish, structural preservation and exceptional spectral performance.

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.

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.
