2.85 Ct. Multi Color Cabochon Fire Opal (Flame Opal) from Ethiopia

This specimen is a translucent 2.85 carat Fire Opal, precision measured at 13.60 by 7.48 by 4.96 millimeters, cut in a cushion outline and finished as a classical cabochon. The opal displays a true microstructure-driven play-of-color, with diffraction effects that yield vivid greens and secondary warm flashes across a neutral to slightly warm body tone. Clarity is graded as eye clean, evaluated at normal viewing distances and ambient lighting, which means no inclusions or structural interruptions are apparent to the unaided eye and the internal color patches remain uninterrupted. Color intensity is medium, calibrated against standard trade scales for opal saturation, and the polish is assessed as excellent, exhibiting a high gloss dome with minimal surface texture and full recovery of luster under bright point illumination. There has been no enhancement to this stone, it is offered in its natural state, and its provenance is Ethiopia, a source known for producing hydrophane and non-hydrophane opals with strong, natural play-of-color. The Natural Gemstone Company sources and documents this piece as a Fire Opal type, emphasizing the warm spectrum behavior and internal fire that differentiates it from common opal varieties.

The cutting approach for this cabochon was intentionally conservative and technically driven to maximize optical performance while preserving weight and structural integrity. The dome profile, with a height that reflects the 4.96 millimeter thickness, is medium-high for a cabochon of these proportions, a deliberate choice to enhance the diffraction of light through the silica spheres without creating excessive stress on the stone. A cushion outline was selected to provide balanced light return and to align the dominant color flash planes parallel to the table, producing broad, linear color patches that read consistently whether mounted horizontally or vertically. Unlike faceted gems where angles are calculated to internal reflection indices, cabochon cutting for opal prioritizes curvature, symmetry, and orientation of color seams, and this piece was hand-shaped by an experienced lapidary who oriented the cutting axis to the strongest color seams apparent in the rough. The excellent polish is the result of a staged lap finishing sequence, using progressively finer abrasives and final polishing agents chosen to avoid chemical interaction with the opal matrix, a crucial consideration given opal’s sensitive silica gel composition.

From an ethical sourcing perspective, this Fire Opal aligns with the values of collectors who prioritize traceability and social responsibility. The Natural Gemstone Company procured this Ethiopian opal through direct relationships with licensed artisanal operations and vetted aggregators who operate within local regulatory frameworks, enabling documented chain of custody from mine to market. No enhancement of any kind was applied, which supports transparency and ensures that the consumer receives the geological and aesthetic characteristics as produced by nature. Our sourcing process includes periodic field audits, verification of fair remuneration practices for miners, and engagement with community development programs that aim to reduce the environmental footprint of extraction through soil reclamation and responsible water usage. For the conscious consumer, owning this opal means supporting a supply chain that seeks to balance artisanal livelihoods with ecological stewardship, while preserving the natural state of the material for long term collection integrity.

In practical terms, this cushion cabochon Fire Opal is particularly well suited for secure bezel or halo settings that protect the domed surface and edges, while allowing the stone’s translucent body and play-of-color to read unobstructed. Given opal’s position on the Mohs scale, approximately 5.5 to 6.5, we recommend protective mounting for everyday wear, avoidance of ultrasonic cleaners and steam cleaning, and the use of mild, non-acidic soaps and a soft cloth for routine maintenance. Thermal and chemical shocks should be avoided, and care should be taken when setting to minimize pressure on the girdle and dome. For collectors, this piece behaves well in rotation with harder gemstones as a statement cabinet specimen or as a focal stone in bespoke jewelry that emphasizes ethical provenance. The Natural Gemstone Company provides full documentation of weight, dimensions, origin, and treatment status with this offering, and we are available to discuss custom mounting options that honor the cutting axis and optical orientation of the cabochon, ensuring the finished piece realizes the maximum visual effect while preserving the natural and ethical attributes that make this Ethiopian Fire Opal a conscientious addition to a refined collection.
