Australian Opal – A Love Story in Every Stone
At Metal & Stone Jewellers, Australian opal isn’t just a gemstone — it’s part of our story. Our passion for opal began on the dusty fields of Coober Pedy, South Australia, where Maurice and Sonya first fell in love with this mesmerising stone — and with each other. In fact, they began their married life living in an underground dugout, dreaming of creating magnificent opal jewellery.
Today, that dream lives on. As experienced opal specialists, Maurice and Sonya are proud to bring you authentic Australian opals, each one reflecting the natural beauty and rugged spirit of the outback.
Whether you're looking for the ethereal glow of a South Australian crystal opal or the striking depth of a Lightning Ridge black opal, we can source the perfect gem to suit your style and story.
Explore the timeless allure of opal — unique, meaningful, and unmistakably Australian.
