Jewellers with a dedication to excellence

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

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

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

Great customer service. Level of knowledge is awesome. Very friendly team and the very competitive pricing. Highly recommend and won't ever go anywhere else.

The Australian Opal & Diamond Collection


Through our ongoing commitment to this precious stone and its status as an Australian icon, we have received continual recognition from the Australian Federal Government. Our prestige is so much so that we have been selected as Australia’s solo promoter and retailer of opals, pearls and diamonds, at two consecutive world expositions, a title which we are very proud to hold and a title that no other Australian jeweller has ever achieved.


From Opal engagement rings, opal earrings, pendants and more, our selection stems from the most prestigious stones manufactured in Australia.
