Australian Opal Shells are among the most iconic and collectable forms of opal fossils. These remarkable specimens are the result of ancient marine shells being replaced by precious opal over millions of years — a process unique to Australia’s opal fields.
Most shells in this collection are sourced from Coober Pedy and White Cliffs, where conditions were ideal for fossilisation and opalisation. Some are full or partial shell forms, while others display fine internal structure and brilliant flashes of colour embedded within the fossil shape.
Highly sought after by fossil collectors, gem enthusiasts, and museums alike, opalised shells blend natural history with gemstone beauty, offering a unique story in every piece.
