Opal Diamond Factory

Our collection of South Australian crystal and white opals, Queensland boulder opals and famous Lightning Ridge black opals is the most extensive in Australia.

John Rynes, an opal pioneer, and Mike Saj-Rynes, a son, discovered a love of Australia's national gem in the red dust of Coober Pedy, South Australia's far north.

At the Opal Diamond Factory, the Rynes family crafts jewellery, including bespoke pieces, from opals, ethically-sourced GIA certified diamonds and other precious stones.

We are proud to have played small parts in thousands of stories - from love celebrations and special moments, to the creation of keepsakes and treasured gifts. Collaboration with our customers is the core of what we do.

Our success is the result of passion and hard work; whether it be cutting rough opals straight from the mine, or shaping elegant, custom jewellery in our design studio.

We invite you to visit our Adelaide showroom or to make your custom order.
