The Lightning Ridge area is a world-renowned centre of the mining of black opals and other opal gemstones. Lightning Ridge has the largest known deposits of black opals in the world . The name Lightning Ridge is said to have originated when in the 1870s some passers by found the bodies of a farmer, his dog and 200 sheep which had been struck by lightning.
