Solid piece of multi colour toned Queensland Boulder Opal on Ironstone.
Boulder opal forms within ironstone boulders, the silica, a key component of opal, is released into the groundwater through the weathering of surrounding rocks, particularly sandstones and mudstones.
Groundwater moves through the rock, it carries the dissolved silica and its this silica-rich water then seeps into cracks and voids within the ironstone boulders.
Over time, the water evaporates and the silica forms the opal, often in thin veins or layers within the ironstone. The opal is typically found in association with the ironstone, which acts as the host rock and provides a unique backing for the opal.
