Closeout Higher Opalescence Australian 30mm x 20mm Oval Boulder Opal Craytex The raising technique described byBoulder Opal is found exclusively in Queensland, Australia, where veins and patches of precious opal form within rugged brown ironstone boulders. These gems developed over millions of years as rainwater dissolved silica from the earth's surface and deposited it into natural cavities within the ironstone. The ironstone backing provides natural reinforcement, making Boulder Opal more resistant to cracks and fractures compared to other opal varieties.
