This is a very rare 'opalised shell' (Shell Opal) and it's found at Coober Pedy, South Australia.
It's unique and great for collection.
Opal fields in Australia formed along the bottom of a large inland sea and different kind of marine creatures such as dinosaurs, shellfish, crocodiles and more would sink down to the bottom of the sea, ended up drying up covered in silica and sand ...
As millions of years passed, this sea with clays and sands that were deposited all over this sea bed, was left with these creatures bones and shells, which actually became the new formation of the opal stone.
Lots of history and miracle hey ?! ^^
Beautiful Australian opal can never be repeat ... fully guaranteed ！✨👍😋
