Boulder opals come from the western Queensland fields
starting with the small opal mining town of Yowah west of Cunnamulla, then stretches up through Duck Creek fields, Junda, then Quilpie and further north through Blackall, Winton and the smaller fields around Opalton.
These fields are quite different to the southern black opal field of Lightning Ridge in that most of the work is done with Bulldozers and excavators and the mines are separated from one another sometimes by hundreds of miles.
In Lightning Ridge, you get the feeling that the small mines are all around the town, which many of them are except the Sheepyards and Grawin mines as well as Coocoran and others.
When a large boulder ironstone is found that has signs of opal, the Miner usually has to break it down with a sledge-hammer. Unfortunately, a lot of good opal is destroyed this way but unless you have very large diamond blades on hand, it’s very difficult to move them closer to civilization so there is little else that can be done.
Most miners get to know the type of boulders they are processing and manage to avoid this problem as much as possible by smashing the boulders in the least likely place to cause damage. Boulder opal pendant like this cluster are the end result of all this hard work.
