About opals

Opal was formed 20-100 million years ago, when there was a large inland sea in Australia. Without going into too much detail, opal is formed from a solution of silicon dioxide and water. Water has run down through the soil and absorbed silica from the sandstone. This silicon-rich solution has deposited in cracks and cavities caused by natural faults or the breakdown of fossils. As the water has disappeared, it leaves behind a silica deposit. This cycle is repeated over very long periods of time and eventually opal is formed. Some of the cavities have been plant material or animal bones. Therefore, we can sometimes find opalized bones, teeth and shells from prehistoric times.
