There are over 200 opal fields in the Lightning Ridge, Grawin, Coocoran and Mehi area. Many of them are relatively newly found, but a number date back over a century to the earliest discoveries of opal. The fields listed on this page are among the oldest and most historically significant fields. This is not at all an exhaustive list!

The information on these pages has been sourced primarily from The occurrence of opal at Lightning Ridge and Grawin with geological notes on County Finch, Whiting & Relph (1958); The Lightning Ridge Book, Stuart Lloyd (1967); Lightning Ridge: Home of the Black Opal, Gan Bruce (1983), Discover Opals: Before and Beyond 2000 with Surface Indications, Stephen Aracic (1996), and oral history collected by the LRHS over many years.
