As water runs down through the earth, it picks up silica from sandstone, and carries this silica-rich solution into cracks and voids, caused by natural faults or decomposing fossils. Opal is formed from a solution of silicon dioxide and water. It takes about 5 to 6 million years to make a 1 cm opal mature. It’s believed that perhaps 30 million years ago, lots of silica was released into a solution that filled cracks in the rocks, layers in clay, and even some fossils.

It is also a dazzling key to Australia’s mysterious past, because buried in the Australian opal fields are fossils of dinosaurs and other strange creatures that lived 110 million years ago, in Early Cretaceous times. ![]()
