Australian Opal
Australia has historically supplied the large majority of the world's fine precious opal, including the famous black opal of Lightning Ridge and the boulder opal of Queensland.
Lightning Ridge black opal is considered the benchmark for the finest play-of-color against a dark body tone, while Queensland boulder opal is prized for its natural ironstone backing that intensifies the visible color. Australia's long mining history and strict grading conventions make it the reference point most other origins are compared against.
