Opal The Phenomenal Gemstone


One of my favorite books at the moment is "Opal The Phenomenal Gemstone". This book has an in depth look at the opal gemstone, where it's found, and how it's mined. The book also features opal fossils found from the Australian opal fields of Coober Pedy, Andamooka, White Cliffs and Lightning Ridge. These fossils are from the Cretaceous period, notable for being the time of the Dinosaurs. The fossils found at Lightning Ridge are different to those of the other opal fields as Lightning Ridge represent a terrestrial environment with freshwater depositional setting. Where the other opal fields are marine depositional environments.

Opal Mining in search of Dinosaurs



Opal mining in search of Australian Dinosaurs has become common practice on the Australian opal field of Lightning Ridge. Fossils from the "Age of Dinosaurs" are commonly found during opal mining. Miners often demand high prices for these treasure as they know that overseas collectors will pay big bucks for these fossils which sometimes have wonderful opal color.
