History of Australian Black Crystal Opal

Opals have been mined in Australia since the late 19th century, with Lightning Ridge becoming the world's premier source for the rarest variety: the black opal. Formed by seasonal rains that seeped into ancient underground rock, silica deposits were left behind to create the intense play-of-color seen today. Indigenous Australian legends often describe the opal as a creator's footprint that touched the earth to bring harmony.
