Vintage Large Australian Mosaic Opal Doublet Oval Cabochon 24.25 CT  ​Capture the shifting colors of the outback with this exceptionally vibrant, natural Australian opal mosaic doublet cabochon. Celebrated as the absolute most fiery of the three spectacular mosaic cabs we have recently posted, this premium piece features hand-assembled fragments of genuine precious opal that showcase an intense, electric play-of-color. Rich, neon-bright flashes of hot orange, fiery red, glowing green, and deep cobalt blue shimmer brilliantly across the dark background, as highlighted across the polished face in photo #1. The back of the cabochon, shown in photo #4, features a smooth, black protective backing, most likely obsidian, typical of high-quality doublets to maximize structural integrity and color brilliance.   Weighing a substantial 24.25 carats and measuring approximately 30 mm long by 22 mm wide by 5 mm thick, this impressive calibrated oval is an exceptional find for custom jewelry designers or gemstone collectors.
