Boulder Opal

Boulder opal is a combination of precious opal and host rock, typically ironstone or sandstone, though some contain vegetation or fossilized wood instead of rock.

The precious opal occurs as patches and/or thin seams attached or surrounded by the host rock. This happens when pre-formed opal silica water seeps into the rock’s crevices before the opal hardens.

The main source of boulder opal is Queensland, Australia.
