Up for sale is a breathtaking 8.59 ct Natural Treated Andamooka Rainbow Matrix Opal, mined directly from the historic fields of Andamooka, South Australia.
Precision hand-cut into a large 20.85 x 13.70 x 4.50 mm pear / teardrop cabochon, this piece exhibits textbook \"Galaxy\" pattern pinfire. Against an inky black treated background, millions of micro-crystalline opal pockets erupt into an intense, full-spectrum rainbow field. Under direct light, the entire face sparkles with vivid fire-engine red, glowing orange, radiant gold, neon lime green, electric cyan, and deep purple.
With a glass-like mirror polish, balanced high dome, and a clean flat back, this large statement gem is ready to drop straight into a custom silver or gold bezel pendant, statement ring, or artisan wire wrap.
