3.46 Ct. Multi Color Black Opal (Dark Opal) from Australia

This listing presents a single, translucent Black Opal Dark Opal weighing 3.46 carat, precisely measured at 14.09 x 7.48 x 4.40 mm, offered by The Natural Gemstone Company. The gem has been fashioned into a cushion outline and executed in a tablet cut, an approach chosen to preserve material and to maximize the face up play of color that is diagnostic of premium dark opal material. Origin is Australia, and the stone is offered without enhancement, confirming that the color and body tone are natural. The tablet cut orientation delivers a low profile with a relatively shallow pavilion, which enhances top light capture while maintaining stability for setting. Overall dimensions and reported weight are consistent with a dense opal matrix, and the proportions reflect an intention to retain optimal carat weight while producing a stable, wearable gem blank.

The cutting style is explicitly a tablet cut, which in practice is a slab like cabochon with a broad, gently domed table and minimal crown taper. In this specimen the table plane is broad and parallel to the finest color seams within the material, an alignment that is deliberate because opal color play arises from coherent layering and from the interaction of incident light with silica spheres. By orienting the tablet plane to the strongest color seams the cutter has achieved maximal color transmission across the face. Faceting in the conventional sense is not applied, rather the cutting technique emphasizes controlled shaping, uniform girdle curvature, and a skillful thinning of the lower edges to avoid white line fractures during setting. The cushion outline provides soft, repeating radii at the corners which reduce stress concentration points, and the tablet proportions are balanced so that the stone can be set in low bezel environments without losing visible color depth. The polish has been evaluated as excellent, with a smooth mirror finish across the table and well blended bevels at the perimeter.

Color assessment identifies vivid color intensity across multiple hues, with primary flashes in saturated blue and green, and secondary occurrences of emerald green and cyan as the viewing angle shifts. Because this is a multi color black opal, the body tone is a saturated dark background that increases perceived color contrast, making the play of color more vivid and legible under typical jewelry lighting. The stone is translucent, permitting internal light penetration that adds to color dynamism, and the clarity grade has been assessed as eye clean at standard viewing distances, meaning no inclusions or interruptions of the play of color are visible to the unaided eye. Spectral distribution is concentrated in the blue green region, but localized patches of stronger green indicate areas of thicker silica layering. Color pattern is variable across the table, with larger broad patch formations interspersed with more linear flashes near the edges, a patterning that reads as a combination of harlequin adjacent to broad flash, depending on angle. The excellent polish and the tablet cut enhance these color patterns by providing unbroken optical continuity across the table, while the dark base tone minimizes light wash and preserves saturation.

For practical considerations and setting recommendations this tablet cushion Black Opal is particularly well suited to bezel set rings, pendants, and bespoke inlay work where a low profile and robust edge support are required. The tablet cut minimizes height, which reduces lever action and improves mechanical security in everyday wear, and the cushion outline simplifies bezel fabrication while presenting a classical silhouette. Because the gem is untreated with no enhancement, mounting decisions can be made with confidence regarding long term stability, provided standard opal care is observed, such as avoiding exposure to harsh chemicals, extended heat, or rapid thermal shock. Given the eye clean clarity and vivid color intensity, the piece is also an excellent candidate for a custom pendant that uses a deep, dark metal backdrop to further enhance apparent color contrast. The provenance from Australia is a key quality metric for collectors, and The Natural Gemstone Company documents the origin as part of our standard disclosure. If required, we can provide more technical documentation regarding cutting orientation, precise weight confirmation, and additional views to assist lapidary professionals or designers in planning a final mounting.
