shop Lightning Ridge Opalized Wood Fossil
Opals are a pseudomorph: they are able to fill in and substitute for another material and form as fossils. In the right conditions, a raw opal specimen is formed in a cavity left by a piece of wood buried in sand or clay. The opal forms a fossil replica of the original object that was buried. Fossilized Lightning Ridge opals are also beloved for their lustrous play-of-color and fire.
