Jewellers with a dedication to excellence

At the Australian Opal & Diamond Collection, we don’t believe in the distribution of subpar, Synthetic or treated Opals. We believe an important part of our role as opal manufacturing jewellers is to use our craft to promote Australia’s national stone. Therefore, the time and craftsmanship our jewellery manufacturers put into the creation of our opals and jewellery is unlike any other in Adelaide.

We believe that each opal has its own precious individuality. Through our years of experience in the industry, dealing with the entire process, from mining to manufacturing through to export. We have found that to create the perfect piece, jewellers need to understand the uniqueness of each opal. We cut each opal individually, taking the time and care to understand the dimensions and colour characteristics of the opal before forging a stunning piece of jewellery.

As Adelaide’s leading jewellery wholesalers, we offer far more than your standard jewellery stores, we care about the standard of your opal and work hard to develop its perfection.
