A true piece of ancient Australia 🇦🇺✨

This rare polychaeta annelida worm burrow from the Blackgate Opal Field captures the trace left behind by prehistoric marine life millions of years ago. Preserved in opal-bearing material, the natural textures and winding structure are brought to life by rolling flashes of deep blue, gold and red that shift beautifully through the stone as it moves in the light 🌈

Fossils like these are more than stones — they’re snapshots of a lost world, shaped by time and transformed by the unique conditions of Australia’s opal fields.
