Large Australian Opal Mosaic Doublet Oval Cabochon 31.75 CT Loose Gemstone ​This striking, large loose oval cabochon features a captivating, multi-colored mosaic design meticulously crafted from genuine Australian precious opal fragments. The geometric pattern pieced together across the face of the gemstone showcases a vibrant play-of-color, flashing intense electric green, deep neon blue, fiery red, and subtle orange pinfires against a dark background matrix. As a classic assembled doublet, the fiery opal mosaic layer is expertly bonded to a durable, flat black backing that intensifies the gem's natural color presentation. ​With an impressive statement size and a total weight of approximately 31.75 carats, this stone measures 36.5 mm long by 27 mm wide and 4.7 mm thick. The smooth, low-domed surface is beautifully polished to a high-gloss finish, making it an excellent centerpiece choice for custom artisan jewelry designs such as a wire-wrapped or bezel-set statement pendant or a collector's pocket stone.
