Grawin Serpentine Opal
Serpentine opal from the Grawin area near Lightning Ridge, New South Wales, is an intriguing variation of opal, often characterized by unique patterns and formations. This region is part of Australia’s renowned opal fields, primarily known for black opals. The Grawin fields are rich in mining history and continue to yield distinctive opals sought after by collectors and jewellers.
In regions like Grawin, opals are mined through small-scale operations often by individuals or families, adhering to strict mining regulations. The geological conditions in these areas have created opals through silica deposits in sedimentary rock over millions of years. If you’re interested in experiencing opal fossicking or learning more about these in Grawin, please call me and I can give you a guided tour.
