At De Giorgi Opal Australia, our story is grounded in passion, heritage, and an unwavering commitment to authenticity. Founded by Tim De Giorgi, a dedicated opal enthusiast with a deep respect for Australia’s natural treasures, our business is proudly family-owned and operated.

Every opal we offer is personally sourced by Tim from the renowned opal fields of Coober Pedy—widely regarded as one of the finest opal-producing regions in the world. Through a valued joint venture with the Smith family, we mine directly from our claim at Hans Peak, ensuring complete transparency and a genuine connection from the earth to you.This hands-on approach allows us to maintain exceptional quality, ethical sourcing, and a true appreciation for the uniqueness of every stone.

At De Giorgi Opal Australia, we don’t just sell opals, we share the story, spirit, and brilliance of Australia’s most iconic gemstone.

Each week we normally run two online auctions. As these days and time can change please feel free to contact us with any question relating to when our next live auction maybe and how they work.
