About Us

The Brisbane Opal Museum is a family-owned and operated cultural institution dedicated to the education, preservation, and celebration of opal. We have curated a modern and accessible space that showcases Australia’s national gemstone and delves into its history, stories, and the people who have shaped the industry.

It all started when Geoff and Val met in London through mutual friends in 2001. Over the years, they co-parent children and co-founded the Brisbane Opal Museum and the jewellery shop together. Their love for opals was guided by Geoff’s brother, John McDonald, when he suggested for the pair to specialise in opals. It was when a miner showed them his hobby box of incredible opal pieces, during their search for knowledge, that their passion for Australia’s national gemstone grew. 

Geoff was struck with what we call, “Opal Fever '' from that first encounter with the miner. His focus has always been to provide customers of the adjoined jewellery shop, the necessary education of their products and its value. He loves collecting opal pieces in his travels, specifically the thrill of when his next big “find” will be. His knowledge of opals is extended through his experience of opal cutting and polishing. 

Comparatively, Val’s love for opals truly developed a little after their exchange with the miner, when she was introduced to an opalised jacaranda seed pod. Having loved fossils most of her life, this was the turning point for Val’s own fascination with opals. As curator, Val’s desire to learn more about opals and subsequently grow our museum is unwavering. Her true passion for education and love for science can be seen throughout the museum as she continues to develop ways to showcase the gem opal and the many incredible pieces in our collection. 

From there, we have expanded into an independent, purpose-designed museum and showroom located only a few minutes from Brisbane’s CBD. 

We are proud to offer a variety of interactive and educational experiences at the Brisbane Opal Museum, with guests able to explore our world-class permanent collection through self-guided or guided tours. From our fossicking table to our exclusive opal polishing experience, there are hands-on opportunities for all ages to enjoy! 

Our dedication to showcasing opals protects cultural heritage and ultimately contributes to the continuous fascination of these captivating gems. This commitment fuels our anticipation of expanding the collection in the years ahead.
