9.09 Ct. Black Opal from Australia

This parcel presents a single, opaque Black Opal, weighing 9.09 carats, in a freeform shape with precise dimensions of 27.00 x 11.00 x 3.60 mm. The piece is a doublet, constructed from a thin natural opal slice laminated to a dark backing to intensify the body tone, and originates from Australia. The cut is recorded as n.a., which in this context denotes a freeform, non faceted profile that preserves the natural surface curvature and patterning of the opal. Color intensity is classified as intense, with dominant blue and green play of color and secondary hints of teal and violet, displayed in broad, irregular flashes across the surface. The optical effect is dynamic when viewed from multiple angles, indicating a tight, coherent silica structure within the opal slice, and the surface exhibits an excellent polish, with a smooth finish and even luster across the top plane. The thin profile at 3.60 mm produces a low dome, which reduces risk of chipping at the edges when set properly, and the freeform geometry offers strong potential for bespoke design integration where the natural pattern is a focal element.

From a lapidary and setting perspective, this doublet demands considered craftsmanship to maximize its appearance and longevity. The backing is integral to the visual depth and should be maintained, therefore reworking by resection or excessive heating is not recommended. Given the laminated construction, I advise bezel or flush settings that protect the stone edges and minimize exposure to mechanical shock, heat, and solvents, since adhesives used in doublets can be compromised by ultrasonic cleaning and aggressive chemicals. For visual emphasis, mountings in warm yellow gold or high contrast white metals will complement the intense blue green play, with a low profile bezel enhancing the freeform silhouette. This Black Opal is particularly suitable for pendants and inlay work where the planar aspect and freeform outline can be showcased, and it will perform well in designs that prioritize surface pattern over faceted brilliance. The Natural Gemstone Company recommends careful handling and routine inspection of the setting, and offers consultation on bespoke mounting options to ensure the doublet maintains its optimum appearance and structural integrity over time.
