The Opal has a wonderful natural opal pattern. Striking blue and green colours thunder down the opal like the rushing waters of a rapid river crashing past the ironstone boulders. This opal has a fantastic picture story going on.
The Boulder Opal has been expertly polished so to keep as much of the Opal as possible.
This natural Boulder Opal was mined in Western Queensland near the town of Quilpie.
