Boulder opal occurs only in central-west and south-west Queensland, Australia. The opal fields are in a 300 km wide and 1000 km long area of deeply weathered Cretaceous sedimentary rocks known as the Winton Formation. Although the boulders are widely distributed in that area, only a small proportion of them contain precious opal.

The term "precious opal" refers to opal that exhibits play of colour.

"Play of colour" means the rainbow-like colours caused by the diffraction of light.
