The remote town of [[Coober Pedy]] produces more [[opal]] than anywhere else in the world. Opal was first discovered near the town in 1915, and the town became the site of an opal rush, enticing immigrants from southern and eastern Europe in the aftermath of [[World War II]].<ref>{{cite web|url=https://www.gemsociety.org/article/opal-mining-coober-pedy/|title=Opal Mining in Coober Pedy: History and Methods|last=Shang|first=Phoebe|access-date=16 October 2022|website=[[International Gem Society|IGS]]}}</ref>
