In our shop, you'll explore the fascinating world of Australian opals—from their origins in the ancient Cretaceous period to the incredible variety found across the country today. Learn how opals formed over 100 million years ago in what was once an inland sea, and discover the unique characteristics of opals from regions like Coober Pedy, Lightning Ridge, Winton and Opalton. Our displays and knowledgeable team will guide you through the different types of opals—black, white, crystal and boulder—while uncovering the rich history and science behind Australia’s national gemstone.

LEARN


Step inside and uncover the fascinating world of opals - beginning with their formation over 100 million years ago during the Cretaceous period, when much of central Australia was covered by a vast inland sea. Through educational exhibits, you’ll learn how silica-rich water seeped into cracks and voids in ancient rocks and fossils, gradually solidifying to create opal—a process that took millions of years.

Explore the journey of opal from the earth to the showcase, with detailed insights into the mining techniques used across Australia’s famous opal fields. Discover how rough opal is assessed, cut, and expertly polished to reveal the brilliant play-of-color that makes each gem unique.

You’ll also uncover the rich cultural and historical significance of opals in Australia—from their discovery in the 1800s to their status as the country’s national gemstone. Whether you're a curious visitor or a passionate gem enthusiast, the museum offers a captivating look into the science, history, and enduring allure of Australian opals.
