Origin of this Opal
Queensland is the only place in the world as far as we can tell, where boulder opal is found.
Boulder opals vary between small ‘nuts’ found in Yowah and Koroit to the south of the state.
Larger boulders with veins of opal range from Quilpie in the south to Winton area in the north.
