0.83 Ct. Semi-Black Opal from Australia

This translucent semi black opal presents as an oval tablet cut, weighing 0.83 carat, with precise dimensions of 9.42 by 4.97 by 2.76 mm, and an intense display of multi color play. The tablet cut produces a shallow profile that maximizes surface flash while preserving material thickness, the result is a broad, luminous face that exhibits vibrant red, green, and blue flashes across the table. The opal displays a semi black body tone that enhances contrast without fully obscuring translucency, the interplay between the darker body and translucent matrix creates depth in the diffraction of light that produces pronounced broad flash patterns and occasional pinfire highlights under direct illumination. Optically the material shows excellent light return for a shallow profile, the color saturation is intense across viewing angles, and the multi color palette shifts cleanly without excessive hazing, indicating a well oriented silica structure and consistent microstructure across the stone.

From a gemological and craftsmanship perspective the piece is graded clarity very slightly included at eye level, with inclusions that are minor and do not interrupt the main color fields or overall pattern, the excellent polish delivers a smooth, reflective table and well finished girdle edge consistent with precision lapidary work. No enhancements have been applied to this Australian origin semi black opal, the natural state preserves authentic hydration and internal structure, and the tablet cut demonstrates controlled material removal to retain weight while optimizing play of color. For setting recommendations consider low profile bezels or tension mounts that orient the table to light sources, the shallow thickness favors horizontal settings that allow full field illumination and showcase the sweeping color patches. Collectors and designers seeking a balance between dramatic color and wearable dimensions will appreciate the technical execution of this piece, and The Natural Gemstone Company offers full provenance details upon request, including origin confirmation and our lapidary notes. This opal suits precision jewelry applications and attentive collections where optical performance, cutting technique, and natural condition are primary selection criteria.
