Na území Austrálie se nachází a také těží přibližně 95 % všech drahých opálů na světě. O zbývajících 5 % se větší či menší měrou dělí asi 19 státních území. Přičemž ve většině z nich se drahé opály pouze nacházejí a jen v devíti státech probíhá i jejich těžba. Australské drahé opály se od drahých opálů nacházejících se ve zbytku světa liší především svým původem. Zatímco ve světě šlo ve všech případech o důsledek vulkanické činnosti a hydrotermálních procesů, pak v Austrálii vznikaly opály většinou jako produkt procesu zvětrávání. Více
