Fossil Opal from Australia

These unclassified pieces of fossil opal Highlight the way that opal forms and how it can replace the shape of the cavity in which it formed. Opal can seep into some materials and then harden throughout the structure. Opalising the internal structure of what it’s infused and creating a matrix of opal throughout the fossil material. When this happens, the fossil can take on the lustrous colours of the opal while retaining its shape and details, producing some astounding pieces.

“Opalised fossils are rare pieces from our past and highly sought after. They generally don’t last long for sale so enjoy these while you can!”

With such a long history and many collectors holding onto pieces either for sentimental or economic value, some of the opals we offer we cannot link to a mine or region. Therefore we offer them to you with the understanding that they could come from anywhere.

At the Opal Shop, we have a diverse range of unclassified pieces from across Australia. We almost always have a video as well as a verbal and written description of the items.
Our price and descriptions are as fair and understandable as possible, decided by the Opal Shop Owner, expert and buyer of 20 years.
