Opal Diamond Factory

Opal Diamond Factory Established in 1974, Opal Diamond Factory is Adelaide’s oldest and largest opal, diamond and coloured gem specialist.

Established in 1974 in the Opal capital of the world, Coober Pedy, and now situated in Adelaide’s iconic Beehive Corner, Opal Diamond Factory is Adelaide’s oldest and largest opal and diamond specialist, specialising is custom made pieces. Our collection of South Australian crystal and white opals, Queensland boulder opals and famous Lightning Ridge black opals is the most extensive in Australia.

Amid the hot, red dust of Coober Pedy in South Australia’s far north, opal pioneer John Ryneš and son Mike Saj-Ryneš discovered a love for Australia’s national gemstone. At the Opal Diamond Factory, the Ryneš 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. Collaborating with our customers is at the heart 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. To view our exclusive range or design your own custom piece, we invite you to visit our Adelaide showroom, or meet us via a virtual appointment.
