These pieces of Australian fossil opal from Coober Pedy 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 has infused. This creates a matrix of opal throughout the fossil material. When this happens, the fossil can take on the lustrous colours of 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!”
