AUSTRALIAN BOULDER OPAL FOR SALE

Boulder opals are a striking variety of precious opal that comes out of Queensland, Australia. While Australia is known for their extravagant black precious opals, the boulder opal is surely giving them a run for their money. The majority of boulder opals are extracted from a Cretaceous stratigraphic layer that spans over 249,000 miles in the heart of the Australian continent. Boulder opal is collected from a few small opal fields in the Quilpie, Winton, and Paroo Shires, with a very small deposit in New South Wales.
